How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for closed-course motocross racing and aggressive off-road riding, not for transportation or general road use.
- Built for
- Sharp, flickable, and eager to change direction, with a stiff perimeter aluminum frame and race-tuned suspension geometry that favor jumps, berms, and rapid transitions over comfort.
- Not ideal for
- This is not the bike for commuting, highway travel, carrying a passenger, or riders wanting a plush, low-maintenance, easygoing ride.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
