MXA 2011 KTM 150 test

[ACMX]

From what I've heard, those manuals are designed to keep the pro riders buying a top end after every third race. I go 30-35 hours. 5-7 races with a practice in between each race. (depending on how hard you revv it, cause you don't have to be a justin barcia to make a bike go fast)

I rev this piss out of mine and got 6 months on the topend obviously thats not straight riding every weekend I would estimate prob 50-60 hrs on my topend, did it myself the piston looked sooo good, the rings were still lookin pretty good. I just change my top end based off compression tests I changed it at 130 psi I prob could've gone another 10 hrs but like I said i'm beyond ridiculous when it comes to that 150. If it's still making good compression there is no need to change it. I use fuchs silkolene comp and pro premix it doesnt have the greatest smell in the world but it keeps everything real clean and lubed awesome, no spooge either.

Interesting dyno chart from a UK mag.
Not sure if the KTM XC & SX have different engines but it is a distant 3rd.
