I ride a 250 XC-F. What kind of gearing combos would you recommend for higher speeds?
I ran 15/38 on the KX, good for 113MPH on the pavement in Baja.15/42 on my KX500 was a good time (but not in the pits or single track)

My KTM 300 is 15/45. A little short for the desert but good all around. If I was doing more single track I would go back down to a 14 front.
