Forged three-piece crankshafts and hard chromium-plated cylinder bore make the engines rugged and reliable. The same applies to the drive shafts, which are made of steel and provided with self-lubricating bearings. Reinforced spark-plug protectors and wear plates protect the machine from the wear and tear of professional use. New for 2005 are the light weight, high torque and quiet 4-stroke engines.
