How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- Purpose-built for competitive observed trials riding, demanding precise low-speed control over obstacles rather than any form of straight-line performance.
- Built for
- A featherweight, razor-responsive two-stroke built around instant throttle response and total chassis agility rather than comfort or speed.
- Not ideal for
- Not suitable for riders wanting a road-legal, comfortable, or fast machine for commuting, touring, or carrying a passenger.
