How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Built purely for technical observed trial competition and obstacle-based riding rather than any form of transportation or speed.
- Built for
- A featherweight, high-precision two-stroke trials machine engineered for extreme low-speed control, throttle finesse, and the ability to hop, balance, and pivot over rocks, logs, and steep technical terrain.
- Not ideal for
- This bike is not suitable for anyone wanting a comfortable commuter, a touring machine, or a bike capable of sustained road speeds, given its tiny fuel tank, no passenger provision, and trial-specific ergonomics.
