Rider Profile

Best ForThis bike rewards experienced or seriously committed intermediate riders who can handle a high-strung, clutch-dependent motocross powerband.
PurposeIt's a purpose-built motocross racer designed for closed-course competition on prepared dirt tracks, not general riding.
Rider FitThe tall 38.2 inch seat height and light 231 lb wet weight demand good leg length and standing-riding fitness rather than raw strength.
CharacterIt has the eager, revvy, feather-light character of a true 250F motocrosser, thriving on aggressive throttle and body-english cornering.
Not Ideal ForThis is not the right choice for commuting, passengers, touring, or anyone wanting a comfortable, low-maintenance street-legal bike.
