Cylinder Stage6 High End R/T Alu. 70 CC One Ring H2O for Mot. Piaggio 50 LC sp.Ø 12

The modular construction makes it possible to mount the cylinder on various engines via adaptor plates and without continuous studs. This way the layout of the exhaust and transfer ports isn’t subject to the limits of conventional racing cylinders; this offers extreme tuning possibilities. Special attention has been paid to the thermal characteristics of the cylinder. The CNC-milled inner head is fastened with five bolts, each one thermally stabilized via an own cooling pocket. This way the critical spots at the studs that tend to lead to piston seizures are eliminated. The CNC-milled adaptor plate is bolted to the engine case and accepts the cylinder via the external studs. In the case of Minarelli engines, the adaptor plate is used to cool the exhaust port from below, which gives another increase in performance.
