Description: ZONGSHEN CB250R 4-VALVE 23HP COMPLETE PERFORMANCE ENGINE ZS172FMM-6 Performance air cooled engine SOHC. Shipping takes 30-48 days for engine to arrive to US location. 23hp 6-speed gearbox Description: New heat engine structure—The integrated overall shape of the cylinder head and optimized cylinder head noise and cooling air passage structure realize simple but stunning appearance and improve the reliability. Four-valve odd-shaped combustion—It improves engine power and torque so that the engine's performance have an obvious advantage among similar products. New design of heat dissipation system—CFD optimization of the flow field outside the cylinder head of the air duct increases the heat sink and meets the cooling needs after performance improvement. Roller valve rocker arm—It reduces power loss and improves engine performance. Lightweight piston—It reduces engine power loss and vibration, improves comfort and extends piston service life.Thickened crankshaft bearing and shortened connecting rod. Crankshaft bearing adopts inner race thickening, enhancing bearing strength and extending service life.The connecting rod length is reduced, reducing reciprocating inertial force and thoroughly eliminating engine detonation.
