The high-revving, 144 cc, air-cooled SOHC 4-stroke Single easily starts with the push of a button. The air-cooled engine eliminates the need for radiators while keeping the chassis slim and lightweight. The 5-speed transmission with manual clutch delivers smooth shifting and acceleration.
The lightweight box-section perimeter frame is made from high-tensile steel for exceptional rigidity and strength. The narrow profile contributes to an easier rider grip and smoother movement on the bike. Working together, the highly capable suspension and lightweight chassis deliver handling that exudes confidence.
Front and rear disc brakes provide strong progressive stopping power. The ø220 mm front petal disc with a dual-piston caliper is complemented by a ø190 mm rear petal disc with single-piston caliper, inspiring confidence on the trails.
