Yamaha Jog Crankshaft (TWH, 3KJ, 4JP, 5BM)

Title: High-Performance TWH Crankshaft for Yamaha Jog Minarelli 3KJ, 4JP, 5BM Scooters

Description:

Upgrade your Yamaha Jog scooter with this high-performance crankshaft from TWH, a leading Taiwanese tuning manufacturer. Engineered with a +2.2mm increased stroke, this full-cheek crankshaft boosts power output by optimizing squish clearance and compression ratio without sacrificing engine longevity. Adjustability is achieved through the use of additional head and cylinder gaskets.

Unlike standard crankshafts, the full-cheek design minimizes the crankcase volume, leading to improved volumetric efficiency. Experience a snappier throttle response, eliminate power dips during acceleration, and enjoy a more predictable and powerful engine character. Ideal for 50cc to 80cc cylinders.

Compatible with Yamaha Jog models including ZR, Artistic, Next Zone, Axis, Poche, and Aprio (1e40qmb).

Please Note: The quantity selection refers to crankshaft variations: 18 = standard DIO, 34 = GB L, 35 = GB LK, 105 = Yamaha Jog.
