The assist mechanism reduces lever effort during operation, while the slip function minimizes rear wheel instability during aggressive downshifting. Gear ratios are structured to provide a progressive transition between speeds. First gear has an overall ratio of 12.21, followed by 9.022 in second, 6.994 in third, 5.641 in fourth, 4.731 in fifth, and 4.131 in sixth. This sequence allows for controlled acceleration and efficient cruising at higher speeds.
Structural Frame and Chassis Composition
The chassis uses a stressed-member design that incorporates the engine as a structural element. The frame is constructed from high-strength low-alloy steel in a trellis configuration. It includes stamped, cast, and forged junctions that are assembled using MIG welding techniques. An aluminum forged mid-structure is integrated into the frame to enhance rigidity while minimizing weight.
The swingarm is also constructed from high-strength low-alloy steel and features tubular sections with a stamped cross-member and forged axle junctions. This design supports stability under acceleration and braking loads. The combination of materials and construction methods results in a chassis that maintains structural integrity while supporting responsive handling characteristics.
Fully Adjustable Suspension Components
The front suspension uses a 43-millimeter inverted fork. It includes adjustability for compression damping, rebound damping, and spring preload. Aluminum fork triple clamps provide additional rigidity. The rear suspension consists of a linkage-mounted monoshock with a piggyback reservoir. It also includes compression, rebound, and hydraulic preload adjustability.
Front suspension travel is measured at 3.6 inches, while rear suspension travel is 3.2 inches. These values indicate a setup that prioritizes direct feedback and controlled movement. The adjustable nature of both front and rear components allows riders to modify suspension behavior to match load conditions and riding preferences.
