Overheating Prevention Tips & Tricks 

3:28 The bike will not get to a dangerous heat level if its radiator, water pump and fans are working properly. The fan coming on is exactly for that reason. If you kill the engine you also stop the water pump, going against what I just said above.

This is a common misconception among some riders. When your fan is on, it DOESN'T mean that your engine is overheating. I live in a climate around 34° to 39°C, my Yamaha MT 07 fan is on and off all the time. But my engine has never overheated. My engine still running smoothly after 55,000 Km.

Older bikes have much less problem cooling down. These new sportbikes are just too hot, no pun intended :P

there are some other tips and tricks to keeping your bike cool. 1. clean your radiator , just with water and a good degreaser. just don't use a high pressure washer , otherwise you might run the risk of damaging your radiator. 2. change out your coolant , it might have been a while sinds it has been replaced. and overtime your coolant loses some of its cooling capabilities. 3. ingine ice coolant , i've used it. and doesn't realy keep your bike from reaching high temperatures . But it does help dispell the high temperatures quiker ones you start moving. 4. aftermarket coolant hoses are often a bit better in cooling your bike , but not by much. 5. bigger radiator of bigger / faster spinning fan. hope this helps you out

Fan starts running at 20c?? Well there goes away my plan to buy a R1 in India where 30-35 is average. It's so hot here that if the temperature drops down below 30c you'll hear people saying Nice weather today.

I installed a manual fan switch. If i know I'm going to be sitting I'll flip the switch early to keep the temps down and the fan still kicks in at normal without the switch. Solved my problem

Modern bikes now come with a waaay too lean air-fuel mixture, which also makes the engine run very hot. If you find a way to put more fuel in there, it will run cooler. I did that on my CBR600RR, installed a power commander and since then not a problem :)

On some bikes you can space the radiator away form the headers slightly which will help. Don't do too much that the front wheel contacts the rad though! Also a toothpick is a good tool to straighten out any damaged fins to bring back some cooling capacity to an older radiator.

Simple fix: just put ice cubes in your fuel tank ❄️⛽️🤣👌🏻

I love the effort that you make to give us content. BTW that r1 is dope!

used to kill the engine at red lights until i heard a theory that the sudden cool coolant rushing through the engine from the radiator when you restart the bike can cause cracking and warping of the heads since they are still heating up due to radiant heat and there is no coolant flow while the engine is off. not sure if its actually something to worry about but i figure the fan keeps my bike at a (high) but safe temperature idling for even the most frustratingly long red lights great vid as always tho mate

Add a switch to turn on the fan also manually (keep the auto fan aswell) and everything is okay. Killing it at red lights will do more harm than help. Starter motor has limited lifespan. And starting the engine puts some forces on many parts.

I live in a hill station, it's literally one of the coldest places in India. Even then, all it takes is 10 minutes in bumper to bumper traffic to make my RC 390 hot and mad af lol

Also straighten your radiator fins from time to time. There are cheap tools just for it. It doesn't usually add a lot, but every bit helps.

I highly recommend you do NOT kill the engine at traffic lights. Not only is it dangerous but this also stops circulation of coolant and the bike will get hotter before it gets cooler. Also, this bike is known for bad starters. They don’t last long due to poor build quality. After I start my bike, I only turn it off when I reach my destination to try to prolong its life cycle. I’ve already replaced the starter once. Do a search and you will see how bad these starters are. You can also have the ECU flashed so that the fans come on at a lower temperature. My bike stays cooler after the ECU flash. Trust me, I know this bike like the back of my hand.

Personally I think killing the engine at lights is unwise, especially if the fan is on. You need the engine coolant pump to circulate heat away from the head and cylinders. My opinion only.

In holland is it summer now.sadly it is raining ,no cooling problems☺😎

I just love watching every single video you make. Top quality and story telling 💪

Use quality oil, make sure the coolant is up to spec and almost any modern sportsbike will be able to run no issue what so ever in 35 degrees celsius. Good idea to keep the revs down when stationary, but dont stress too much about it... Seriously

Guys chill down, this video depicts a operating fan as engine overheating lol. A operating fan is completly normal. Check your service manual for the critical temperature(actual overheating!!!) and just ride ... ridiculous.

there is nothing much you can do if youre standing in traffic , the fan will do its job and its all good, but if you have the chance to ride on hige gear on 3-4000 rpm it will cool your engine quicker

If your bike is overheating in normal operation regardless of outside temp, then you have a problem with your bike or the bike is underspec from the factory in terms of cooling, i.e. undersized radiator, etc. I live in a very warm country (up to 32 C regular day time temps) and my bike runs up to 89c the fan will turn on and cool the bike down to 82c, fan then stops. This is even standing still.

Nice meeting you at the track today!

Another issue that you're facing is altitude. 1700m above sea level, thinner air, less efficient cooling. Add in the higher air temps, the air thins more, even less efficient cooling.

roll with the clutch from time to time so that the rpm will go down. for example don’t use the motor break in downhills. rather stay in high gear and keep the clutch in. and of course try not to go over 8k rpm if you really want to play it safe. stay in higher gears!

Like always, amazing video mate. Superb editing and cinematography

On my VFR there is this known upgrade to a VTR fanblade. Straight drop in, should keep the bike nice and cool.

.. As always..., nice videos..Chaos Causes. Subscriber here from the Philippines...

I've heard that through a ECU flash the fan can be set to kick in earlier.

Lowering your revs does NOT cool the engine. It's your throttle use that will heat or cool the engine. More throttle is more heat. However! If you want to accelerate (fast), higher revs actually COOLS your engine vs lower revs. Why? Because more cool fuel and air is injected into the engine. Applying throttle with low revs / high gear will stress the engine more and heat it up. People who often climb mountains with their car will be able to confirm this, as you can overheat your engine when you would climb in too high a gear. Lowering the gear, i.e. turning up the revs, cools the engine in this situation. So do not lower your revs, limit the throttle input instead. Your fan turning on is normal system behavior and normally not something to worry about. When you drive in cooler climate as well, your engine is supposed to heat up and the fan will be needed to keep it within healthy range. As long as your coolant doesn't cook (you'll notice when this happens), there's no need to worry. Also, as other people below already stated, don't turn off your engine at short stops.

I didn't know all of those stuff, thanks for sharing it!

My RC 51 has this problem! That fan doesn’t turn on until 218F and then cools to 207F. I got after market fans and a manual switch, hoping that helps!

Overheating is only a problem when ur Fan is permanently on... Not only some times, and bro, all those expensive additive products for the cooling fluid arent really necessary... When you're about to fill in Water and the coolingfluid u only need a tenth of the fluid and the rest is good with water, the water is that fluid which grabs the warmth out of the engine, the other one is only in the cycle for no corrosion and that the waters point for freezing is going down, so at those temperatures you dont need that much! Greetings of Germany ✌️

Oil is the first level of cooling so keep the (warm) level topped off at the high mark. Use a good full synthetic brand with a high flash point & 100C cSt viscosity

I just installed a race-spec radiator on my buddy R6, added more heat shields to guide air away from engine, more water than coolant and even expensive oil.

CC with his little tips & tricks 👌 always producing good content in extremely good quality 👏👏 sadly the uk 🇬🇧 summer is coming to an end very soon here so I’m not going to have any overheating 🥵 issues for a while but its been a great year for me upgrading to my first litre bike 2016 “ZX10R” and just recently ive brought myself a 2016 Audi A5 S-Line cabriolet so i can’t complain to much!! Keep bringing your videos to YT bro always enjoy them 😊 Adam 🏴󠁧󠁢󠁥󠁮󠁧󠁿

You can actually ECU Remap the thing so the Fans start working at a lower degree level and keep the bike cooler...

Thanks for another helpful video

Fully faired, high compression, 4 cylinder sportbikes will inevitably run much hotter than a regular octane standard bike

Using just distilled water with coolant ( regular coolants actually runs hot they were made for cold places ) is not a good idea though I have 08 R1 it was running way too hot for my liking and comfort zone unfortunately cooling fan not kicks in until 220degrees I didn't liked that did plentiful research this really really worked. this summer I changed it with HOAT coolant ( Toyota has best ) mixed it with ionized water not just distilled water it's a bit expensive but sure it works. Hope this helps

Great tips. Nice R1! Stay cool!

I have a 2018 636, and unfortunately, the fan will only run while the engine is running... my friends older CBR would actually keep the fan running even if the key was out

heyyyy bro, you're my favourite south african youtuber and my question to you is would you ever plan a group ride of some sort?

Hahaha my bike is roasting hot !! Even in UK 🇬🇧 cold weather !! Radiator fan is good to reduced overheating issues

I there’s a coolant that I run in my ktm125sx called engine ice it’s supposed to keep your engine cooler by 10 degrees

It's a R1, it's supposed to run hot. I've had two of them and it's one of their traits because their exhaust pipes run very close to the oil pan hence the propensity to get hot. Add in the hot summer months and sitting in traffic,it's gonna get hot!. The only fix is to get a larger radiator!.

I ride an 06 ducati s2r1000, its air cooled but has an oil temp gauge, stop and go traffic on a hot day makes me cringe because I'm watchin the oil temps climb higher and higher all way up to 228° at which point I pulled over. It is absolutely nerveracking and I hate it lol need a bigger oil cooler or something

Nice filming and editing

Love it once again! Quick question, in SA what are your thoughts of riding a bike? Is the area u in "friendlier" to bikes? And how is it riding a litre bike knowing that the roads are dangerous especially in SA, and does it help?

R1 is notorious for getting stupid hot not to mention the heat on your ankle!! I think the thermo fan doesn’t even kick in until 105c?! My cbr954rr really only ever hits 101c then fan brings it back to about 96c on a 25c day.. Basically buy a 954rr for commuting and an r1 for track.

Well i live in Iraq...it's 45° to 50° all summer for about 4 months stright, so yea engine overheating is really a problem not just bikes but for cars too 😂😂

Different issues, different bikes. I got a 1299 Panigale S...it gets very warm! Which is great for winter in Sydney...not looking forward to summer :/ Edit: another great video though mate, it's an issue worth looking into for sure.

What a good video CC

Dude i have a doubt, your r1 version have halogen headlight doesn't that radiator fan and the headlight kill the battery eventually, due to kill switch applications when the radiator fan is on. And also I seen many r1 (not the led headlight version) struggling to start after kill switch application while the radiator fan is running.

Excellent video

My bikes fans come on after 15 mins of riding. Is that a problem? I dont live in a hot state.

Move to the UK? Or is that too cold for you?! 🤔😃

Good video!

Is it possible that exhaust modifications can make a bike run hotter? I live in S. California where during the summer there are weeks with consistently above 95°F temperature. On my Triumph Bonneville the Cat is removed and so are the mufflers.

Hi, that was really helpful. I have a query. After riding around 2500 kms on my new motorcycle, I noticed my reservoir coolant level was just below the low mark. But the radiator was full. Is it okay? Thanks in advance

New subscriber here at Philippine i like your chanel you took a lot effeort to your video pls keep posting

wow I live in a climate constantly in 35-41 degrees and its considered normal here

Motul ~ Mocool Additive, next Coolant change, Is meant to work & if yoU respect your Machine change oil every 4500 mls

If the temperatures that hot out and my bikes running that extreme I will shut the engine off at a light I also run a full synthetic belray oil can handle extreme heat better than conventional mineral oils

try 45c like here in Texas LOL...

My bike always goes up in temp whenever I'm at a standstill like at a stoplight. Only when I get the bike moving again does the needle drop down cooler........ is that 'normal' for motorcycles? I'm a new rider and whenever I see that temp gauge go up, I start to panic and shut off the motor at a stoplight.

Anyone have tips to keep the engine cool ? Or what part must be changed? 2013 r1 . Its almost cant be riden in daily traffic .

Enjoyed!! 👌🏼👌🏼👌🏼

What about oil cooled bikes? Like the hyosung GT 250R?

I'm a big fan and follower on insta too :D But I don't agree with "Kill the Engine" at a red light. I'm from India and nowadays, here the temp is around 30 Celcius and I ride 390 Duke Today it went hot again and RPM was not going above 5k RPM so I have to drive it below that RPM. If I killed it might not start again until it reaches the desired temp to start.

Haha 21C is hot for you around here people start wearing jackets at that temperature 🤣

killing the engine at red lights isn't actually that good, although the fan may still kick in the water pump wont, as it's powered by the engine, and the coolant may get cooled down in the radiator but it wont circulate to the engine to cool it down, instead the engine will boil on the inside while nice cool coolant is still in the radiator

Wouldn't keeping the revs higher spin the water pump faster... Making the coolant circulate ?

Great tips but my bike doesn't have a radiator. However, some of it is applicable. Thank you.

Just fit a secondary fan that you can keep on constantly when its warm out side

At what rpm should I be cruising at? 4000

Also check that both radiator fans work

I have no cooler fan so my sound is a ”tssssss” instead of a fan noise

Immune!! Naked bike life!

Few wrong facts. When you shut the engine off the temperature will actually go up this is called after boil. Also most engine will run hotter at low rpm because you are not flowing much coolant because the water pump spins faster or slower with rpm.

Bro its how much power yamaha r3 2019 Please tell me

Ok, Johannesburg is your city. However, cooling fan turns on doesn't mean engine is overheating. Even in cold winter, cars fan comes on not much as summer

I have a manual fan switch and if it gets really hot I wash the bike

Yesterday at stop light my R6 went from 99 to 110. Turned off the bike n after turning on after maybe 15 secs it went back to 98. Centigrade

I live were sumers are 32 and winters are 24

wich shark helmet is that its nice!

So I have to keep revs as low as possible, but need to move as fast as I can to dissipate heat... I got it, load it up on a trailer and drive fast lol

Did u keep the r6?

Notif squad

😑, here in Indonesia normally 35 degree Celsius, and sometimes it goes to 40, so, yeah, that 21 degree are nothing to use, that is Lower than how i set my ac at home 26 Celsius

OIL!! Oil is the first level of cooling: keep your warm oil level topped off and fill w/ full synthetic.

Meanwhile me here looking how to cool down my air-cooled engine. "sad face emoji"

Can someone tell me how to change Fahrenheit to celcius on my Yamaha R1 2014?

To my experience below 40-50 kph not much cooling going on

Killswitch at 21x degree realky does not help, heat still builds up and fans kick in. Unless you turn off the key 😆

I live in a country where the 27 degrees celcius is considered cold .-.

I guessing you don't have that problem now, eh? ... Please do an update for UK riding.

Haha just back watching this again :)

Most of them don't go with my carburated air cooled bike :(

I have used the Evans waterless and the Cyclelogic Engine Ice brand coolants, for better cooling.
