How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for competitive and recreational trials riding, focused on tackling obstacles, steep climbs, and technical terrain at very low speeds rather than covering distance.
- Built for
- A featherweight, high-clearance, short-travel-suspension tool that thrives on precise throttle and balance control rather than outright power or speed.
- Not ideal for
- This is not the right bike for highway travel, carrying a passenger, commuting, or anyone wanting a comfortable seat and long-range fuel range.
