SIP CRANKSHAFTS
The SIP crankshaft line is manufactured in Italy and meets the highest performance and reliability standards. Special attention has been paid to the quality of materials and precision design. The balance of each crankshaft is adapted to the stroke, connecting rod length, and scooter model, ensuring smooth and reliable operation.
Distribution
125°/-5° rotary disc valve with intake timing extended by approximately 20°. The longer timing is ideal for sporty tuning, while maintaining good performance even in everyday use. The engine maintains power at low revs and is easily optimized. Backfire from the crankcase is kept low, and the contour of the intake manifold is designed for the most aerodynamic gas flow possible.
This type of cheek also allows for particularly effective balancing of the crankshaft, ensuring smooth engine operation even at high revs.
Note: The SIP crankshaft rotary vane cheek is precisely matched to ensure smooth operation. Aftermarket housings or defective vane surfaces may cause contact between the crankshaft and the housing. It is recommended to check the dimensional accuracy before installation.
