This doublecradle design has become famous throughout the world for its ability to withstand the gruelling treatment of hillclimbing Jumping and motocross sports. Front Forks In order to smooth out road roughness and reduce vibration felt by the rider thereby lowering. riding fatigue, this bike is equipped with ultra-responsive race type front forks. These optimum-stroke forks are specifically designed to yield the best stability. while allowing maximum maneuverability Rear Shock Absorbers In order to further increase the stability of the bike. the hydraulic rear shock ab- Sorbers are designed for an optimum Stroke. S-step adjustable to compensate for load and road conditions, the design assures good surface tracking ability even while carrying widely varying loads, and the exterior style of the shocks lends iselt to the overall good appearance of the ma: chine Mutter The muffler is routed up from the center ‘of the engine and tucked under the seat in order to maintain the overall slender profile of the bike.
