Vertically split crankcases feature a built-in oil pump, reducing weight 5.1 ounces compared to a conventional design. Exhaust system uses a lightweight titanium exhaust header and repackable aluminum muffler with stainless steel pipe. Dual radiators provide significantly more surface area and more effective heat dissipation compared to a single-radiator design. Gear-driven balancer reduces vibration and drives the water pump. Eight clutch plates provide the surface area necessary to handle the engine's massive torque, while carefully matched clutch springs provide a light feel at the lever.
Primary kick starting system allows starting in any gear.
Tall swingarm pivot plates and thin frame spars create a narrow overall frame cross-section for superb rider comfort and maneuverability. Two rugged box-section rails attach to the base of the downtube and support the engine. A forged aluminum steering head provides a compact and extremely durable mount for the frame spars and engine downtube. Compared to a conventional design, front wheel unsprung weight is reduced by 3.5 ounces. Together with a revised rear wheel, hub and spoke design, rear wheel unsprung weight is reduced 15.9 ounces.
