I know this is a very vague question but what kind of miles does the average sport bike get out of an average abused but maintained engine? looking at 600cc more or less.

 

my guess would be a very long time.

 

well i have 29k on my 04 750. ive been sprayin nitrous on the motor for 12k+ miles, i beat on it doing stand ups, i beat on it in general, and maintain it. and i hope to get another 29k out of it

 

90% of the serious damange comes when pushing the motor for the last 10% of performance. Change the oil and filter regularly, keep it out of the red, watch for leaking hoses, change the coolant once a year and everything should be fine for many, many years.

 

I have an uncle that put 200k+ miles on a Kawasaki Zephyr 750. Delivery service in PR. Not really abused, but still... Shows a bike can go as long as car...

 

raul i lived in pr for 3 yrs.... i use to ride a 96 kanatuna 750 there and those arnt exaclty 200k+ easy miles. lots of hills and crazy driving. thats actually pretty impressive

 

They are like anything else, the more you take care of it the longer it will live. Keep up on the oil changes and regular maintinance and you won't have to worry about the engine life.

 

ok, thats good to know. I was just wondering because it seems like people are shying away from bikes with 15k miles or more. I wasn't sure if the 15k mark was like the 100 or 150k mark on a car.

 

I had a 2000 R1 with 15k miles on it and it ran perfect.

 

i know a dude with a f4i and he has 80k + miles w/o any problems
