Hello all,

I was just wondering if riding at high rpms can seriously cause much engine damage. I own and ride an R15 and it's redline is at 10500rpm, but i usually shift at 6500 to 7000 rpm and often gun upto 9000. When I'm on long rides, I maintain an average engine speed of 8000rpm. What are the long range consequences of such a riding style? If it is truly harmful to the engine, does it make any difference if i change the engine oil more often?

Welcome to XBHP, appreciate if you can post an intro

Few of the things that I can think of apart from regular stuff that you may be aware of
- Leads to increase vibration sooner & cause rattling that causes some of the loose bolt/nuts to fall off
- Causes wear & tear sooner (valves, sprockets & chain, timing chain, rings, connecting rod & bearings) than anticipated time
- Results in high maintainence

Changing oil more often does burn your pocket & at the same time gives a little peace that the cooling is better at the same time ensure that the oil pump is in very good state

Yes, it was a case with older bikes. But, modern day bikes are much capable of doing high RPM rides. And especially a Liquid cooled, forged piston bike can easily do that. It doesnot matter's at which RPM you are riding untill you are under acceptable limits, but 'How one reaches a particular RPM' is the real culprit. Get easy on throttle while approaching higher speeds, donot gun the throttle like trigger of AK47 that keeps on shooting.

Errr...my points are above are not for easy on throttles; should've bought it out earlier. Sorry!!

You shall have zilch problems at 8000rpm on an R15 even for extended periods,

@rider, It also depends on which type of bike are you using. For Ex a good 4 stroke performance bike can handle these rpm. Ex. Pulsar 150cc can handle these types of rpm and will not have any effect on the engine.Even if it has then it is minimal, since it is built in that way. In 2 strokes, this will have a bad effect as said by @aargee and as everyone told it is not advisable to hold on for that rpm for longer period of time on any bikes.

By the way @aargee, nice to see you in this forum also.

unnecessarily riding the bike in higher rpm will definitely be not good for the engine.

I remember what Joel had said about the R15 engine. Although it revs high compared to our standard engine, it still is a very safe setup. And Yamaha has done a clever job restricting it to 10,000 rpm.

As far as I know, its a machine. Any machine, run slow, at 50% load can run longer, more consistently and more reliably than one run at 85% load. Agreed, motorcycles are made that way, especially the r15. But in general terms, yes. Riding hard all the time is more bearing upon the engine than riding easy.

But that shouldn't stop you. Even with hard riding, the engine is capable enough to handle all the abuse (speaking of the R15 here). And as per Yamaha the block requires no re-boring throughout the lifetime of the engine (such is the hardness of the cast).

i agree 100% to this as i have experienced it myself as my normal style of riding is fast riding on highways, and i normally travel on highways only...city commute is very less.

right ....modern bikes are very much capable of doing high RPM rides but if you do that quite often your bike will surely suffer ....and as a result your maintenance cost will increase....you can have years of fun on the bike riping it as hard as you can but you have to pay for the maintenance.

and if after purchasing a 1 lakh plus bike and that too a track oriented bike......what is the point if we can't gun it like an AK-47. we could have purchased a P220 instead (with no offenses meant for P220).

not now but after some time it may have problems.



i have a pulsar 150 dts-i UG3, my riding style is extremely fast and my riding consists of 90% highway and 10% city. i had to change my block piston at 25000 KMS had to redo crackshaft etc. etc. had changes my rear wheel bearing twice till now (60000 KMS) had changed rear sprocket bearing 3-4 times till date, even though i do regular servicing every month at every 2000 KMS. the point is that high speed riding means high maintenance. and most P150 & P180 riders here on xbhp with my style of riding will agree to what i have just said...and at every servicing when i drain the used oil, only 500 ml is left of original 1000 ml that i pour in at the time of servicing.


see ....hard accelaration and fast riding too often or regularly .....will definitely increase your cost of maintenance....although R15 is supposed to be made for this kind of riding.....it should not have any problem doing that in the short run and even in the long run it should outlast any other indian bike since it is supposedly built to do eaxctly that, so it should not have any major problem say...till 30000 to 50000 KMS on the ODO....

but as i have earlier said the point is that R15 is a bike for track, and so if we can't gun it like AK-47, nobody would like to pay 1 lac for just looks.

so the verdict for you buddy is you can ride the way you want it .......BUT never ever skip a servicing. KEEP SERVICING THE BIKE AS MENTIONED IN YOUR USER MANUAL AND AS RECOMENDED BY COMPANY, USE GOOD QUALITY OIL AND YOU CAN HAVE FUN WITH YOUR BIKE THE WAY YOU WANT IT.

(assuming that you don't want to use the bike for 20-30years. 5-7 years down the line, you might have upgraded to a better bike or a car)
