Racing cylinder VMC ET6-60 for Vespa Smallframe engines from 50cc (with 125cc crankshaft)
displacement and power aluminum cylinder with wear-resistant Nicasil coating.
The cylinder has generous cross-sections and head angles. It is therefore predestined to generate a sporty performance characteristic. The cylinder can be adapted very well to the desired application via the exhaust selection. Exhaust systems such as the VMC Evo52 enable high revs, a peaky performance characteristic along with the typical 2-stroke bite. For those who prefer a touring oriented engine with early torque and good pull already from lower rpm, choose e.g. the VMC Siluro exhaust
.
Exhaust cross section: Ø32mm
Distance exhaust studs: 56mm
Crush edge: 1.1mm (+/- 0,1mm)
Tightening torque M6 bolts 10-11Nm, M7 nuts 11-12Nm
SPECIAL FEATURES
Since the cylinder is designed for high power output, it has a generous overcurrent area at the cylinder base. Therefore, a small amount of machining of the crankcase is required for installation. This involves removing the crescent-shaped protrusion of the fan wheel tunnel. In order to mount the large cylinder base in the engine case, the diameter of the case must be enlarged. For this purpose a milling template is included in the kit. This is mounted on the motor housing with screws and serves as a guide for a hand-held milling cutter (Dremel/Proxxon). Alternatively, the housing can also be professionally machined on a CNC milling machine.
