Building on the success of its crankcases for the Vespa PX and T5 ranges, tuning firm Pinasco has released three reed valve crankcase options for small frame Vespas.
All versions feature larger bearing seats, reinforcement on critical stress areas, and an eight-petal reed block. The crankcases include all studs and gaskets required, and see the introduction of a system which allows the gear cluster to be changed without removing the engine from the frame. The three options are the Slave8X naked, the Slave 8X51 (with a 51mm stroke crank) and Slave 8X54 (with 54mm stroke crank). Prices are £780 SRP for the naked, £1195 SRP for the long-stroke options.
