Aluminium twin-tube frame design features frame beams that go over engine, allowing a narrow construction that is easy to grip with the knees.
Lightweight and highly rigid, the frame uses the engine as a stressed member. The frame contributes to handling, offering a firm, planted feeling, good stability and light, nimble turning. The frame is a 5-piece cast aluminium construction, consisting of steering stem, left and right main frames, and two cross pieces. The two main frame components have open C-shaped cross sections and were die-cast to ensure a smooth surface finish.
