which pipe and gearing combo?

You won't notice the extra 2 or 3 mph because you'll never be riding at that speed for a lengthened amount of time. To spend the money on a new sprocket and pipe would be stupid, it's 2/3 mph for crying out loud. ;)

well the smaller the front sprocket the quicker the motor will rap out-
i have a 11 on my kx 80-- lots more bottom :nod:

Just wondering why you would want more top end on a trail bike? Personally I went from my trusty but heavyweight klx250r for more trail oriented power of the kdx.

Granted i ordered a rev pipe and will have it ported but i LOVE instant gratification! you just dont get that even with my modded klx.

the klx was plenty top end-ish but lacked the grunt for deep sand I sometimes find myself in, and I was either leaving everyone behind,working my butt off trying to stay on top or workin my butt off trying to stay with the group. Don't get me wrong, as I still ride and enjoy it and will until it is finally sold, it just 'feels' limited and cumbersome in much of what I find myself riding in.

Basic/moderate trails, it excels. The trickier the trail the more work and less enjoyable it becomes. For the record in a 100 yard drag race i will pull my buds 03 rm125 then lose at the short end but make it a 200 yard race and i will retake him.

Point being: in my neck of the woods, i rarely have enough space to take advantage of any top speed, so why bother? is that the type of riding you most often do?
