Why you need top-end changes to make your 500 a screamer

Recommended Posts

This is a great watch, and it does a really nice job of explaining why the 500 won't be a screamer (top end focused power) without cam and/or head changes.  I love the KTM 500 motor, it's spectacular for off-road, but I've seen several posts from guys trying to get SX like power from the 500.  Maybe this will help guide them. ;)

500 = long stroke and 450 is short stroke version. long stroke is better torque and short stroke gives better revs
