FEATURES AND BENEFITS
POWER UNIT
The 25B and 30H engines are designed to provide superior fuel economy, serviceability, and
durability.
They are based on the previous 25V and 30G with newly designed linkage that controls both
throttle opening and ignition timing mechanically and simultaneously.
Special attention was paid on the crankshaft bearings. Collar is added to the upper main
journal of the crankshaft. Roller bearing is applied to the center bearing.
The collar added on the upper main journal contributes to get better serviceability.
