Has anyone done any gearing down on final drive for '07 KTM EXC 525? Awesome bike, but geared too high for single tracks. I usually do versatile riding: the terrain in AZ changes severely, so as type of riding: from flying open desert to navigating highly technical steep rocky single tracks. I wouldn't mind to sacrifice some top speed in order to gain that low end torque on first three gears. Other than that... the best set of two wheels- great weight/power ratio. I had to strip all that "european" stuff: huge controls/housings, blinkers, 3' long tail, extra covers, key ignition and fork lock (duh! try to deal with it if you loose your keys out there in the desert!). Any experience with this bike or similar?
