Chrome composite plating on the lightweight aluminum cylinder promotes rapid heat transfer and superb wear resistance. Improved low-rpm response comes care of a new reed valve stopper shape. The revised shape improves scavenging efficiency by facilitating better airflow through the 3 rd scavenging port. New piston profile helps to reduce mechanical noise caused by piston slap. New KIPS valve O-ring offers improved sealing performance. KIPS valve spring length is adjusted for the new sealing method. Close crankshaft web to crankcase tolerance promotes strong primary compression. Crankcase design eliminates cast-in main bearing bushings to save weight while two large cooling passages efficiently cool around the exhaust port. New crankshaft secures the primary gear using a key and lock-nut (instead of a snap ring). The reduced play helps reduce mechanical noise. 2005 Model 2006 Model 2005 Model 2006 Model 2005 Model 2006 Model
