■ Details
Since the generator of GROM MSX125 MSX125SF is mounted on the L. crankcase cover, the direction of attachment of the flywheel is toward the outside (the tip of the shaft)
For this reason, the rotation weight increases of the flywheel hangs outside the tip of the crankshaft, and especially modified engine doubles the burden during acceleration and deceleration.
This may affect the ignition timing that the generator and flywheel interfere, in the worst case the crankshaft may be damaged.
By providing ball bearings inside the stator, this product changes the crankshaft journal portion from 3 point support to 4 point support, and restricts crankshaft runout occurring in the high rpm region of the bore-up engine.
By limiting, vibration can be suppressed, and the durability of the stock crankshaft can be enhanced.
