How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built as a pure motocross competition machine, it's designed for closed-course racing on dirt tracks rather than any form of street or general-purpose riding.
- Built for
- It has the character of a razor-sharp, lightweight racing tool that thrives on aggressive throttle input, high-rev power delivery, and precise rider inputs through corners and jumps.
- Not ideal for
- This is not the bike for commuters, touring riders, passengers, or anyone seeking road-legal comfort and low-maintenance simplicity.
Scores are derived from the spec sheet using the same model across every bike, so they compare like for like.
