Why don't you do the wheel revolution calculation?

Measure the distance traveled with one full revolution of the front wheel... I did that on my KTM and it was dead nuts when checked by my gps....

if you measure the tire accuratly the vapors are super accurate! I bet its your buddies stock 250X that is off:hmmm:
