QUATTRINI CYLINDER KIT M1-L-60-GTR 144CC FOR V50
Product Code: CST15058000
The long established M1 kit has been re-bored to a diameter of 60mm increasing its capacity to 144cc! Five transfer ports including two supplementary Boysen ports (extra inlets, directly to the transfer channels) ensure a solid supply of fresh fuel charge to the cylinder. A large exhaust port with two large side ports, a centralised cylinder head and an Italian produced piston possessing a 1mm thick HQ ring are further well known details of this range of cylinders. Although the M1-60 cylinder has been bored out to the limit, the motor casing must not be machined to fit this cylinder kit, as opposed to the M1L-60 with its 9mm cylinder base height. All of the M1 cylinders are 'plug and play' in combination with the specially produced QUATTRINI Vespa small frame motor casings.
The M1L-60 with its cylinder mounted reed valve manifold has four large reed petals especially to fit its XL dimensions. This kit for street and touring use, although those with racing ambitions should also be more than satisfied
