New, lighter magneto rotor uses powerful neodium (rare-earth) magnets to lower inertial moment from 6.5 kgžcm 2 to 4.0 kgžcm 2 which improves low-rpm response. The rotor boss and yoke are now unitised. The unitised piece is both smaller and more durable, offering improved overrun performance. Engine kill switch now attached with a waterproof coupler for more reliable connection. A stopper added to the oil seal of the left crankcase improves engine reliability. New gasket material for the generator cover, water pump cover and water pump elbow are changed from paper-base to metafoam (SPCC+foam) to improve sealing. Likewise, the clutch cover gasket has been changed from a paper-base to a metal-carbon composite (SPCC+carbon sheet) material. (SPCC: Steel Plate Cold Commercial) The clutch basket and hub ride on involute splines and are fastened with a circlip instead of a bolt to ease servicing. The steel clutch plates have a special surface treatment to improve the feel. 6-Speed transmission features a short shift lever that keeps the shift throw short for quick shifts. The ends of the shift forks are hard-chrome finished for added durability. The shift drum rides on roller bearings for smooth shifting. The fuel tank cap vent hose has a check valve to reduce the possibility of fuel seepage. 2005 Model 2006 Model
