Confident Handling

Lightweight frame

Extreme hardness and strength are offered by a lightweight box-section perimeter frame containing high tensile steel. The shorter profile helps grip the rider and allows more fluid movement on the motorcycle. Highly efficient suspension and lightweight chassis work together to create reliable handling.

Powerful electric start

The 144cc air-cooled SOHC 4-stroke engine starts quickly with the touch of a button. Air conditioning eliminates the need for radiators and allows a smaller and lighter chassis, while a 5-speed transmission with a manual clutch guarantees smooth shifting and acceleration.

Front and rear disc brakes are reliable.

Front and rear disc brakes offer powerful, progressive brakes. 220mm front petal disc with dual-piston caliper and 186mm rear petal disc with single piston caliper provide ground confidence.
