SIP Lambretta Performance and Premium Crankshafts | NEWS
SIP for Lambretta
With supplies of Tameni’s good value black-web competition cranks now dried up after the closure of the company people have been looking elsewhere for good value sports cranks.
SIP Scootershop are now doing more and more Lambretta parts and this new range of Italian-made competition cranks looks like being very popular due to keen pricing.
They are only available in GP style flywheel taper, but with a choice of 58mm or 60mm stroke. Two different rod lengths are also available: 107mm is standard for most LI-series models and 116mm for the TV175 engine and various kits like the RB20.
Finally there are also two different qualities of con-rod available. The cranks with the standard finish rod are called SIP Premium and are priced at £148. The ones with the polished con-rod are labelled SIP Performance and retail for £228.

“This brand-new range of SIP crankshafts are 100% ‘Made in Italy’ and easily fulfil all of the above listed requirements, especially concerning the high-end quality and well-conceived constructional features. Every single crankshaft is balanced to be compatible with the stroke, con rod length and model of scooter to which it is fitted.
We have two versions of these crankshafts available. The ‘Premium’ models are equipped with a high end ‘standard’ type con rod, meaning that the surface is left untreated. This version of the con rod also possesses lubrication slots and holes for both the big and small-end bearings respectively. The ‘Performance’ crankshafts however have an extremely high quality con rod included. The polish it receives upgrades the surface finish, providing it with a more stable molecular structure which makes the con rod tougher and more enduring. The smoother surface finish also helps reduce the turbulence in the motor, while simultaneously saving a lot of weight. They have a gas-flowed profile and have a revised big-end design, improving the lubrication of the bearing located there.
