New Features
- New seat now features textured side panels for maximum rider control.
New Engine
- Redesigned cylinder exhaust ports to improve power and torque output at mid-high rpm range and maximum roll on acceleration - Main exhaust ports are enlarged to 42.6mm - Sub-exhaust ports are re-shaped to be narrower and shorter - Port timing is advanced by 0.5mm.
New Chassis
- Engine placement has been revised by tilting the engine slightly forward in the chassis. As a result the drive sprocket is now 3mm higher, resulting in a more stable movement of the swingarm and improved rear wheel traction in the whoops.
- Front and rear suspension settings are revised to work with new drive sprocket position and for improved traction.
- Front fork upper holder is now removed for reduced weight.
Engine Features
- 249cc, two-stroke, liquid-cooled, reed-valve intake engine has 66.4mm x 72.0mm bore and stroke.
- Digital CDI to match ignition timing to throttle opening for strong response.
- Six speed transmission with heavy-duty multi-plate clutch.
Chassis Features
-
Strong and lightweight single backbone, chrome-moly steel frame combined with rectangle cross section aluminum alloy swingarm for maximum strength and minimal weight.
- Renthal tapered aluminum handlebars with Renthal-labeled handlebar pad - lighter than standard bars - rubber-mounted to reduce vibration.
- Showa 47mm inverted dual-chamber forks are fully adjustable and built with an emphasis on better cornering and straight line performance. Compression and rebound damping valve settings are set for smooth mid-stroke movement and maximum overall suspension balance.
- Showa piggyback reservoir shock absorbers are fully adjustable for high & low speed compression damping, rebound damping and preload with 12.2 inches of wheel travel.
