The range of performance cylinder kits for Vespa is topped by the Quattrini cylinder kits in terms of performance and quality. No other kit on the market can match the power of the kit, and the utmost reliability from an all alloy cylinder with Nicasil lining.

The M1X MilleMiglia is a 172cc kit which can be fitted to all Vespa PX & LML stars of 125cc & 150cc, giving not only an increase in cc, but a substaitiol power gain. Further more the M1X kit has now been joined by the M1XL kit, which features a direct intake via reed valves. The direct intake version comes with a 30mm carburettor manifold, and your original crankshaft intake has to be sealed off, but all this gives even more power!

Both kits are have a 62mm bore diameter, 6 port cylinder, come complete with a central plug cylinder head and the engine casings should be modified for the larger transfers, but no welding is needed.

The 125cc kits for the smaller framed Vespa PK range match the larger kit in terms quality and power which is second to none. Again available in both standard and crankcase reed induction versions the rred valve version features boysaeen ports for added power.
