How to break-in a new engine is an extremely contentious topic. In this video from the MC Garage we bust the engine break-in myth by building up two engines, breaking them in using drastically different methods, and then tearing them down and comparing the components at the heart of the discussion.
--
Getting a new motorcycle is an exciting prospect, but once you fire it up for the first time you’re left with what many deem a great responsibility: breaking in that new engine. What is engine break-in? Fresh from-the-factory parts appear smooth, but they actually have microscopically rough surfaces that need to rub against their counterparts and bed in, and that happens during those first miles of use. Once the components are polished smooth and broken in, friction is reduced, sealing is improved, and you’re ensured good power, fuel economy, and reliability. There are a lot of sliding and rotating parts within an engine, but what everyone gets riled up about when discussing engine break-in is the seal between the piston rings and cylinder walls. And rightfully so. Ring seal is the key condition that’s going to affect performance and longevity, so it’s worth thinking about.
How Should You Break In A New Motorcycle Engine?
What’s the best way to get a good seal on those piston rings? If you follow the break-in procedure outlined in your owner’s manual, it’ll recommend a 600, 1000, or even a 1500-mile process wherein you limit throttle and revs and constantly vary the engine speed. At the other end of the spectrum, there are people that say a gentle break-in is a waste of time and not an effective way seal the rings, and that a more condensed and aggressive break-in-some would say brutal-is the way to go.
How We Conducted Our Engine Break-In Test
To answer the question once and for all, in this MC Garage we assembled two identical Honda CB300F motors with fresh top-end parts, broke them in differently, and then compared the results.
The first engine was installed and run in gently as per the manual, which meant painstakingly limiting and varying the throttle and slowly ratcheting up the revs over the course of 1,000 miles. Then we swapped out the babied motor for engine number two. While engine one didn’t kiss redline until that final 1,000th mile, this second engine was given a minute to warm up and then taken right to the limiter and ridden at or near WOT on the highways of SoCal for the entire 1,000 miles. Both engines were initially filled with Bel-Ray semi-synthetic oil, and we changed the fluid and filter at 600 miles as recommended.
After breaking the engines in using drastically different methods, we performed compression and leak-down tests-which is a standard way of checking top-end health-then disassembled, measured, and inspected the internal parts. And the results, well, they might surprise you.

Engine Break-In Specs
Engine 1, “By The Book Break-In”
Installed at 1,828 miles, removed at 2,861 miles
Break-In Notes: Ridden gently. Didn’t exceed 50% throttle or 5,000 rpm for the first 600 miles, and didn’t exceed 75% throttle or 7,000 rpm until 1,000 miles. Didn’t experience WOT until 1,000 miles was accumulated. Ridden with constantly varying engine speed and load, no easy task on a slow bike in a busy, urban environment! Oil and filter changed at 600 miles.
Piston OD: 2.9910” at install, 2.9910” after 1,000 miles
Cylinder ID: 2.9925” at install, 2.9930” after 1,000 miles
Top Ring End Gap: 0.0130” at install, 0.0145” after 1,000 miles
Compression: 235 psi hot after 1,000 miles
Leak Down: 4% hot after 1,000 miles
Engine 2, “Brutal Break-In”
Installed at 2,861 miles, removed at 3,890 miles
Break-In Notes: Went to WOT within moments of first starting up, and was ridden hard for 1,000 miles. Did everything we’re told not to-lots of throttle and high-speed droning at steady throttle. Oil and filter changed at 600 miles.
Piston OD: 2.9910” at install, 2.9910” after 1,000 miles
Cylinder ID: 2.9925” at install, 2.9930” after 1,000 miles

WOW! The soft-break-in engine impressed me! ALL engines are broken in roughly - first start, from factory, they warm up the engine then do a full dyno run, 1,2,&3rd. Twice! SO - point is, what impressed me the most is that an engine that did not get its proper wide open first start (which is what they did, when they built the motor themselves, no dyno) I was impressed that it seated the rings at all!! :D Different strokes for different folks, I guess :) I prefer a "proper" break-in, but the southern version of "proper" lol - not rough, but also not gentle, neither - I don't need to hit redline right out the gate, but get on it!! Keep the RPMs varied, downshift a LOT to maximize blow-by protection, and don't be scared of 'er! Do it right & you can really feel the moment that all the parts hook up!! It's like hitting the power band on a 2-Stroke, and your engines will last you forever!

@HIGLEGaming 4 месяца назад

not even close to "every" factory does that. they also don't dyno every engine. that's a waste of everything lol. and they most definitely don't max it out. they normally just cycle thought the gears lightly to see if she's workin.

@buddywilson104 5 лет назад

Sir, this was one of the best videos I have seen.

@ProPatriaRO 4 года назад

Ok, as an engineer (propulsion specialist) my opinion on this is the manufacturer recommends breaking in the engine slowly because the chances of defects in the materials or manufacturing are still there and failing at 3000rpm with destroy the engine but most likely will not kill you, now 13500rpm and 100+ mph, having a piston blow, stoping your rear wheel will most likely kill you. I actually went through something like this, an intake valve seal failed and because i was at low rpm, was able to drive to the shop with no major damage done.

@thonczarenko 5 лет назад

This has always worked for me resulting in long lasting high performing engines. Hard acceleration and the lower gears (1-3) in short bursts is critical for the first 30 miles (rings seating), while letting the revs come down slowly with closed throttle to pull out any break-in particles. Do not lug in higher gears due to the bearings breaking in during the first 600 miles.

@zypp33 5 лет назад

Great to actually hear it from the top! I found a harder break in with BMW twins seemed to give long-term better mpg, performance and less oil use. On the K series, it made no difference, but each could just be the as-built variations of the engine. Hope recovery goes quickly, looks like it seriously hurt. Good luck in the new venture. I've got so much out of your vids, so thank you.

@Jeff-Vader_head_of_catering 4 года назад

Agreed. I like his final point of not just the engine breaking in, but the tires, suspension, and you getting used to the bike too. Very good points. As for the controversy, what I've come across is a lot of 'know-it-alls' who don't have a degree in anything, let alone engineering, spouting their opinions as fact, and calling anyone who differs in opinion, every curse word you've ever heard. Clearly, these are highly intelligent individuals. 🙄 For myself, I look at it this way: If the manufacturer is recommending the process, and ultimately it's going to be the manufacturer who is responsible for replacing any parts (or the entire engine) if anything fails after following their recommended break in process, why not just follow it? It's only 600 miles. I bet there's already someone typing the response "but if they can't tell if you broke it in hard, then..." They can tell. This video talked about there not being any discernable difference in the parts, he didn't say anything about there being burned oil on valves or cylinder heads, which is a dead giveaway for excessive heat and rpm. To each their own. I'd just much rather know that I'm definitely covered under warranty, than be told "sorry, you didn't follow break-in procedure, and thereby voided your warranty".

Thanks for the painstakingly long process of assembling and disassembling the two engines. Yes I was surprised by the results too.

@mpc07005 Год назад

The only indicator I would expect to vary would be surface finish characteristics (not just Ra, either) and initial wear patterns, which weren't discussed. Break ins are intended to control these parameters in sliding and mixed friction surfaces of the piston walls, the various plain bearings, and transmission gear faces, and ultimately impacts how the elastohydrodynamic layers of the lubricating oil films form on these surfaces. Large dimensional changes of the components are not what break-in if for, if there was a problem with the metallurgy (gross dimensional stability) a break in would not have any affect for typical materials used. It would also be more interesting to see on a 'lesser' motor, it is very possible that Honda tolerancing is sufficient that no real break in is needed, which is the case with many modern engines.

@The.JZA. 7 месяцев назад

I’m breaking in my new CB650R right now, up to about 100km ridden so far. I was pretty gentle with it for the first 10-20km and then as I got used it it I started riding it similar to how I ride my old bike but just without any WOT and only revving it to like 2/3rds of max rpm at the most. I’m kinda just riding it at medium pace and varying the rpm, gear etc and making sure I don’t lug it at low rpm. Really enjoying it so far and I can’t wait to wind it out to 12,000rpm. Even the taste that I have gotten so far is pretty delicious.

I think the video presents some really interesting points regarding engine technology, the fact is that specific design differences are an important consideration. For instance, when I rebuilt my Porsche 914 engine and replaced the cast iron cylinders with nickasil lined aluminum cylinders "ring seating" was no longer a concern and revving to redline wasn't an issue.

Glad to know I won't need to worry about the engine too much.

For example, I don't remember my dad EVER breaking in a new lawnmower....... always just put oil and gas in it and used it! I'm still going to try and be easy on my engine though. It's just common sense that the less strenuously you use something, the longer it will last. There are lot more moving parts than just in the top end, of course. That being said, this video gives me more peace of mind about occasional high revs on a new top end! Thanks for taking the time to do it!

The only time I know of (professional mechanic for over forty years now) for being critical in regard to "break in" is for flat tappet motors. Back in the day when every automobile motor had flat tappets, pretty much all motor oil had a high zinc content, so you never had to think about it. Nowadays you have to specifically look for it and stay with it. Motorcycles have had roller lifters in pushrod motors for a very long time so it was never really an issue. Anything with overhead cam where the rocker makes direct contact with cam lobe and valve stem does not need a break-in, nor has it ever.

@andrewsanders6270 3 года назад

I've been a machinist since I was a kid , and a motorhead. Good video. Truth is if something isn't engineered and or machined and or assembled , properly there will be above average / premature wear. If it is done properly there won't. The valve face and seats will beat themselves in slightly within a couple minutes, the rings and bores same . Bearings and bearing clearances are either write or wrong. There's no magical best way to do it . I say run them easy = no more than half throttle for 1st half hour , change oil . Run it up to 3/4 throttle half an hour and change oil , then start nailing it whenever you want. If it was such a big deal new cars and bikes would have alot of problems and they don't because modern materials and machining and finishing practices are so good. Bores are soft honed to reduce acsesive wear and heat , and what is just as responsible for sealing rings as bore and ring face quality, is the gas pressure behind the ring or rings that pushes it out towards the bore wich is why larger rather than smaller ring gaps are bennificial. Lastly overheating a new engine in particular is the worst thing for them . Really they're either write or wrong .

Im really glad it popped up in my head to look up a proper break in procedure. Buying a new motorcycle had me a little nervous. Thanks!

@hotdogandahayride9823 3 года назад

I broke in my 1998 ZX-9R "by the book" and ended up with a less than ideal break-in as the piston rings hadn't worn enough to make full contact with the cylinder walls after several thousand miles. So yeah, that was 23 years ago and things might be different now, but I still take a middle ground approach when breaking in a new engine.

@Yaboifootchie 2 года назад

I think that proper break in is not keeping revs low. Break in is conservatively exploring the entire rev range, slowly working your way to theupper bands. For example, get out on the highway, go 75, but switch between 6,5,4th gears. Then do it at 80. Then at 60. Just focusing on not dogging it out. Also allowing proper heat cycles for start and shutdown. This is what we do with new jet engines and piston motors in most cases. For some jets we go up to slowly work up to 80% rpm, then sustain that for 20 minutes. The next day the jet goes to 100. For our piston airplane motors, most of them need to fly at 2400 rpm, (idle is 800, redline 3500) for 2 hours on the first flight.

@JETZcorp 3 года назад

Some piston rings throughout history have come with a coating that was meant to be worn away, and this was the real point of the break-in. Before the coating was worn away, end-gap would be very tight and hard running could potentially lead to a seizure, especially in 2-strokes where things can heat up (and cool down) really fast. It was also the signature calling card of older Wiseco pistons (and what lead to a number of myths about forged pistons). This is definitely still a thing depending on the manufacturer of thr rings. This coating situation was meant to shorten the break-in time compared to a plain cast-iron ring, which can take quite a while to mate fully to the bore, but loses less end-gap in the process.

@MVanDii 5 лет назад

I think you missed the purpose of the "brutal" route. The idea is to put the motor under a heavy load (heavy throttle in too high of a gear and engine breaking). Higher RPM is more like the "by the book" but louder.

@Mytwistedvoices 5 лет назад

I was told break in was something done decades ago. When machined tolerance weren’t has close they are today. I still have to break in model airplane engines. They don’t machine them to the tightest tolerances. you can hear the changes and running temperatures gradually get cooler.

Never cared about breaking in, just ride it. Casual downtown riding is good enough, you can't go full throttle for too long anyway.

@derf9465 5 лет назад

Taken a few engines apart and those that have been ridden hard from cold and new, have the edges rounded off their piston rings. I just break them in slowly and seem to last for 10's of thousands of miles, before I have to rebuild

@CanyonChasers 5 лет назад

This is really an outstanding video. The only thing I would have liked to have seen would be the "after" dyno tests. Was there any difference in final performance numbers? When I was working at a shop, we had a demo bike, that was caned and brutalized, and a customer bought the same bike and babied it. The customer bike came back for a power commander and a dyno tune, and for fun we put the demo bike up on the dyno too. The demo bike made more power. This is no where near as precise as this video, but why I would have like to have seen a dyno run done on both bikes after break in, particularly, since the video did mention there was a difference in End Gap.

@AceNZ1964 3 года назад

Back in the olden days (1980 ?) I bought a new XS250 special , The twin engine was so tight that it would lock the rear tyre on down shifts around town in the lower gears. It took a few hundred km's to loosen up and then give it some red line. I was eagerly waiting for all the extra power to come in once I finally reved the shit out of it, but was disappointed when nothing really happed. Should have waited for the RD250LC Doh ! Still had a lot of fun on it. Hope the face has recovered by now and Cheers from New Zealand.

@nortondlcl 5 лет назад

I'm not surprised in difference but BMW s1000RR motors where having more problems before 600 miles break in, I would still suggest old school variable throttle 600-1000 miles. Oil ? Simi synthetic oil as a industry standard is only 10% synthetic to conventional !

@desertfresh3740 5 лет назад

That was only the earlier models. I broke my 2016 S1000RR in HARD. One thing that does seem to help us the 9000rpm rev limiter you get from the factory, which is removed at the first service. I took mine in at about 450 miles instead of 600.

The Dealer mechanic told me to take it easy during engine break in but I couldn’t help it. Once I got home I was hoping I didn’t mess something up haha.

@StephenWhite55 5 лет назад

This testing was a great service, and I certainly appreciate it - thank you! However, there is one obvious test that you could have performed, that is conspicuously absent here: Oil Analysis! Why didn't you send the used crankcase oil from both engines off for analysis, to see what it showed? I realize that a brand-new engines won't show drastic differences, but given that you couldn't find ANY differences worth mentioning, this would have been (potentially, anyway) very illuminating.

@sootrattlerolloff-road1415 2 года назад

I've had my last 5 bikes dyno-tuned with power commanders and pipes, all with less than a hundred miles yet on them. In the case of my 2012 V-ROD Muscle...it now has over 100k on it, with zero smoke at cold startup, and zero problems other than the wideband O2 failed and was replaced. The second high mileage bike that was ridden hard and put up wet after each ride, several of those to and from Sturgis, from Indianapolis, is my 2013 CVO RK...was dyno tuned and piped with 175 miles on it. That bike now has 85K on it, and of course is air-cooled, and runs like new. Only issue is the one it was born with...top-end rattles in traffic from high heat, but not even that over and over has caused a lasting dependability problem. Then there's the bike in my profile/avatar or whatever...2012 CVO Convertible...the same air-cooled 110 in the RK...it became my wife's bike, but not before the un-broken-in dyno tune and pipes, and my big ass thrashing it for about 20K. Sold that bike but, I'm friends with the dude who bought it, and he still rides it today with zero issues...not sure about the miles but he seems like he told me it's around 60k now. My point in this ranty post?....these are Harley's man - you know, the bikes so many thick-heads say are junk. If these "Junk" bikes make it through entire normal bike life-expectancy without sissyfied break-in periods, shouldn't Japanese and Italian bikes make it even easier? I mean sure, don't bounce it off the rev limiter on that first tank of gas, but even if you do, it will be ok. A run on the dyno isn't exactly a gentle run! If something comes undone in that engine, it likely was going to at some point anyway. Best that you find that weak-link while it under warranty vs babying it so it waits until AFTER warranty to present itself. When I spend 35 thousand on a bike, that sucker better blow-up under warranty.

@northerniltree 5 лет назад

My first new bike in 1976 (Kawi 125 2-stroke enduro) was to be babied as per break-in specs. But, alas- my high school classmate wanted to race the moment I got the bike that took me 2 years to save for. He had the same bike. He took off like a shot, I didn't. At first. Screw it, I gave it good throttle, got up to 65MPH, flew over a small hill in the road and was partially airborne when I smashed into him. He stopped to wait for me where I couldn't see him! The bike flew into a ditch, stuck at full red line RPM. I stumbled about accessing lost skin and ground down kneecaps at first oblivious to that screaming engine 200 ft. away. Finally, I got to it and hit the kill switch. That bike lasted me for years, went 25,000 miles without a rebuild, and took me from Illinois to Colorado, including great mountain trail riding. My knees mostly healed. Ari, I'm tellin 'ya- you'll be fine!
