How can I get more top end power?

12 posts in this topic

So I bought a 2011 yz450f and I read many reviews on the 4th and 5th gear being flat so I'm trying to figure out how I can get more 4th and 5th gear power for those long wide open desert rides

go downilll on 4th and get it to redline and shift to 5th it should be going pretty smooth lol get an exhaust pipe a k&n filter and a 50 tooth rear sprocket

The OEM muffler seems to be the limiting factor on the '10/'11. They use a sudden reduction in diameter at the end of the outlet as a noise cheat, and it ends up clipping power on top. The header, OTOH, seems to be just fine, so a well made slip-on is usually enough.

if your looking for more top end speed a slip on exhaust may help a little, but gearing is the way to go. Try going down a tooth or 2 on the rear sprocket size.
