How it rides
Editorial estimate from the spec sheet - not lab tested- Best for
- It exists purely as a closed-course motocross racer for the 150cc amateur/expert class, engineered to be pushed hard around a dirt track rather than ridden on the street.
- Built for
- It delivers a high-revving, peaky powerband with sharp throttle response and razor-quick handling, rewarding aggressive riding over jumps and through rutted corners.
- Not ideal for
- It is not suited to street riding, commuting, touring, carrying a passenger, or any rider expecting comfort, low-end torque, or road-legal equipment.
