31-Year-Old 125 vs Modern Race Bike! MOTOCROSS SHOOTOUT 

She's such a sweet little bike and the PC pipe makes her sing! Thanks for watching Chris :D

Love them Suzuki RMs.

@@999lazer and can you explain exactly in great detail the entire process of why that PC pipe makes that two-stroke sing and so far of my last 10 years of surfing RU-vid no one has ever been able to do that to explain exactly what it does.. As I have been through high School shop classes and on into automotive schools small engines diesels and graduated with an associate degree in applied science with a doctor of motors degree that isn't even applied today and numerous service schools for trucks cars and motorcycles but it wasn't until 5 years after graduation attending a Honda service update as the R&D facility in Milwaukee Wisconsin ironically right across the street from the old Harley Factory.... I was introduced to a man by the master ceremonies that claims our new instructor could tell you what you had for breakfast by reading your spark plug.... And his name was none other than popular the world's greatest tuner of motorcycles ever past present future and the inventor of the two-stroke Honda Elsinore and also the one who designed the oval Pistons of the NC 500 22,000 RPM four-stroke Honda with eight valves two connecting rods for each oval piston.... And was also the only man in my years of study and informed information whoever explained how an expansion chamber design for a two-stroke creates horsepower and it's nothing that you think it is it has nothing to do with physical back pressure measured in PSI as if there is one ounce of that it won't run it all.... So tell us and let's see if you're one out of a million who actually knows what's going on

Made me think of cherry scented two strokes lol!! With the neon colours, the good old days

Acoustic scavenging.

Thanks for watching dude! I couldn't recommend vintage racing enough, so much fun! :D

@🍉MelonCannons🍉 for sure. I had a 95 yamaha with a purple frame and back then i turned it black and white but now id rock it! I loved the neon bikes in the 90s!

A lot of the reviews I read from the time said that the RM was really built for Supercross. The way it could turn tight and the punchy motor combined to make it a serious indoor weapon. I hope that bike of yours gets to see the dirt every once in a while... ;-) Thanks for watching as always!

Well for sure when you get back into 70s and early 80s bikes where they had steel tanks and rear suspension was the two springs one on each side not really unlike a street bike they are night and day different from like mid to late 80s when they got plastic tank and the modern one big rear spring suspension

I'm really enjoying making these videos, so we'll definitely have more coming this year mate. We shot a very special video today that'll hopefully be ready for next weeks upload! :-D Thanks for the support as always dude

Had one too! Great bike, the footpegs were pretty bad, (they bend and they wreck boots, I had to modify them)the kick-start would break easy, but good bikes otherwise.

Thanks for watching and taking the time to comment Darren! :D I think it just goes to show it's all down to how hard you twist it. It might be a more comfortable, easier ride on the modern bike, but if you grit your teeth and pin it these old girls are very capable!

@@999lazer I was surprised to hear the side-by-side video and the motors sounded nearly identical. Great comparison !!

90 percent rider. 10 percent bike

Hey John, thanks for watching! That's an interesting theory on the headshake, i'm not too keen to go out and test that though! ;-D haha

So rad! Sounds like you're doing it for team 2 stroke there Hayden. Thanks for watching dude

Team 2 stroke :)

Thanks a lot dude, the support from you guys means a lot! :-)

Awesome, used to have a two stroke Toro. Would put my race gas and Motul in cut lawn.

A quad? Bugger that. Get a proper bike again.

Thanks for watching Dylan! Oh man, that's gonna be sweet. There's nothing that handles quite like a Suzuki!

Sazuki 2 strokes were some of the best. Too bad their modern 4 strokes suck these days

Nice dude I’m building a 2004 right now

@@hayden6119 nothing wrong with the late 450's you probably just suck at riding them 😂

Totally agree. The 91 actually had a yellow frame back in the day, but Sean thought that blue would look better and he was absolutely right in my opinion! Thanks for watching Michael

Mine was a '76 B model. When those came out they were Elsinore eaters! I was like you to ride the fire roads in the local hills and did not race as much.

Thanks for the kind words Lukke! Those RM's really are legit head turners, much more so than the CR's i think. Keep it pinned dude

2 Strokes for life brother! Thanks for watching Franco :D

Thanks for tuning in Gazza! I have to say i really enjoyed riding that little RM, it was definitely more effort to wrangle around the track but the smiles were huge :-D

Cheers Tim, thanks for watching

Thanks for watching dude! This was a real fun one to make, i'm loving this format :-)

@@999lazer Don't call me dude........ LOL!!!!

Totally agree Doc. For the most part bikes are only receiving minimal upgrades/gains each year and as we just saw even over a 20 year period that doesn't add up to much on track when the stopwatches are out. I don't think a bike 20 years older than the RM would have a hope in a lap time showdown!

Yes, but that's just with 2 strokes. With 4 strokes it's completely different...

Motocross bikes peaked out in the early eighties as soon as all of them were water cooled ... Like this 91 Suzuki makes it 38 horsepower for a 125 and this newer Yamaha only makes 33 horsepower and today the new Husqvarna TC 125 two stroke makes 40 horsepower... The very first 1973 Honda CR250 Elsinore made 29 horsepower at 8500 RPM.... Allow me to clue you in the secret about liquid cooling as it is not designed to get rid of more heat to make more power the engine is actually run hotter than the older air-cooled motocross engine.... But that is the magic as more heat you can hold the more horsepower you can make and the big kicker here is the fact that with a liquid cooled cylinder it stays perfectly round at all RPMs under all conditions and an air cool cylinder does not..... Smokey Yunick famous stock car builder turned the NASCAR upside down when they discovered that he would machine his engine blocks with water and antifreeze running through the system at the same time under the same temperature he would operate the car on the track and that was way up there around 210 Fahrenheit or better ... This guaranteed Smokey that those old Chevy engines that he was massaging we're running perfect tolerances and perfectly round cylinders through the whole race while engine blocks bored cold do all kinds of weird things when you're screaming 9,000 RPM making 800 horsepower and getting hotter by the second... Another Factor you guys should look into is the process of making cash Pistons under what they called high pressure extrusion cold die casting.. this is the process where the aluminum is almost cold enough to become a solid again so it takes hundreds of tons of pressure to push this Play-Doh into a diecast mold that's a diecast itself is made within tens of thousands of an inch torrances and the Piston needs no machine after it's extracted from the mold this does a number of things.. one the extreme high pressure cold die casting piston is damn near as tuff as a forged piston that would that was way more advantages over a forge piston for a toMotocross two-stroke engine. ... A catfishing for Motocross 2-stroke engines are your only choice as they barely expand much at all under heat and pressure for a forest fishing grows like a weed and just as fast and soon become junk very quickly destroying your whole engine stay away from forged pistons.. And the big kicker here is you can fit these high pressure extruded Pistons much tighter at only 0.001 inch of piston skirt too cylinder wall Clarence.. Andy's new high pressure extruded Pistons are 6% less friction than anything else before. As as it is Honda car company has been using these types of pistons in there 4 cylinder little Honda cars since 2006 as Honda was looking for gas mileage savings and I do that also but who cares on a motocross bike but it could make a difference between winning a Enduro run or not

@@levisylvester Today a brand new Husqvarna TC 125 two-stroke produces 40 horsepower and the whole bike only weighs 192 lb... Something that none of you understand or have ever thought about or have ever been shown how it does it but two strokes are self supercharging engines making boost with intake boost ports forcing the air and fuel into the combustion chamber at higher pressure than the atmosphere we call that supercharging. Show me a four stroke that can even come close and you only see about half the performance and much harder to ride and a piece of crap of a money pit ...as two strokes make boost four stroke suck

@@donniebaker5984 thx for writing a book for me🤣 I did know all that already but it was still interesting. All I mean is that an 90s 450 Has no Chance against a modern 450. I wasnt comparing 2 to 4 strokes.

Trust me, I'm working on it! ;-D Thanks for watching dude

Agreed. My ‘98 RM was a ripper right out of the crate. It could be taken to the track and capable of winning local A class races with no modifications.

@@johnseaark8706 Yes sir... I turned Pro end of 97', and started my '98 season on the' 98 model. I had Cernics mod the engine. It was a badass bike.

Such a sweet little bike! Thanks for watching Johno

@@999lazer brilliant video mate loving the old school 👌🏻

The RM was so fun to ride! You'd think that the small gains made each year would add up to more on track, but at the end of the day i think it's mostly just down to how far you want to twist it! lol Thanks for watching dude

Yeah its crazy. I come from snocross and snowmobiles have had TREMENDOUS changes in 30 years, almost entirely different. The snowmobiles they used to race with 30 years ago were really shit. But motocross bikes were way ahead of snowmobiles I guess back then.

I have a new GasGas EC 300 and a 30 year old Suzukin RMX 250. The old Suzuki have no problems hanging with the new bikes. I kind of prefer the ergonomics of old bikes. To be honest it’s all rider, not the bike.

@@Checkyoursix77 Very interesting! Isnt the new bike lighter and have better suspension though?

@@swedish_sadhguru3854 The weight is about the same because the newer bike have electric starter and a battery. The suspension is better on the new bike but in my opinion the right setup with right springs is more important. The biggest problem with older bike is the spares parts.

Thank you guys!

As we've just seen ;-D

"The Hurricane" and Brad "Bad Brad" Lackey were my MX heroes as a kid. I loved the RM125 through the 80's.

Yes bob and Brad were awesome back in the day. There is a vid on you tube of the hurricane talking about the 89 rm if you just type in 89 rm125. And check out the motocross files here on u tube they have all the greatest riders on there lackey Hannah ward ect. Take care 👍

Thanks for watching as always dude. I think that might just be the way I layered the sound in the edit there, the bikes sounded very different from each other in person

Thanks for watching dude! :D

You be proud of that old girl my man! ;-D As Sean proved, age is just a number right?! Thanks for watching always bud

Maybe the yellow frame was powder coated blue??? Also in 1991 they went to showa front forks and I believe the 1990 had KYB

Sean predicted that someone would pick up on this, so he armed me with the right responses! lol You're right the yellow frame was powder coated blue just because sean thought it looked nicer and the KYB stickers on the forks are literally just stickers. It's definitely a '91, but Sean restored it with his own twist. Thanks for watching Mike :-)

@@999lazer Very cool I love the look of the 1990 better. I noticed it had showa forks with KYB stickers. My daughter now races my old 1990 RM and hauls AZZ. Keep the 2 smokers alive!!!! The world of MX isn't the same without them.

90 engine by the looks of it 91 had the a clutch cover in two pieces I have an 89 and this is identical Great video though 🤘🤘

It isn't that they are overlooked. It is Suzuki always had trouble producing the bikes in big numbers.

Such a sweet little bike! Thanks for watching dude

Thanks Tony, an honor to have you watching again :-)

Thanks for watching dude! :D

I also have a 1990 RM 250 and my other bike is a 2010 RMZ450. Both run like new. My ole RM 250 was feared back in the day.

Hi Michael, my YZ has had quite a few upgrades to it (VHM head, V Force reeds, HGS Pipe, and long rod conversion) the RM on the other is stock (other than the Pro Circuit pipe) Sean restored the bike and gave the top end a service but it's not been messed about with at all in any other way. Thanks for watching Michael :-)

@@mr.matteroffact2822 two strokes are self supercharging engines whereas four strokes can only rely on the atmospheric pressure as they cannot make boost at all.... Just remember two strokes make boost 4-stroke suck

@@donniebaker5984 I can say this, my 250 2 stroke power curve is like a turbo and my 450 runs more like it’s supercharged. Thanks for the feedback

@@donniebaker5984 I opened up the air box on my 450. She was starving for air.

Thanks Chris

Thanks for watching dude. I agree 100% i've ridden both 250 and 450 RMZ's in recent years and they might lack in power and tech but the handling was always top notch
