Description
Racing cylinder VMC ET7 Ø60mm - 144cc for Vespa Smallframe engines from 50cc (with 125cc crankshaft)
High-capacity and high-performance aluminum cylinder with wear-resistant Nicasil coating. Bore: Ø60mm
Stroke: 51mm
Displacement: 144cc
Exhaust: 188° (three-piece)
Overflow: 128°
The cylinder has generous cross-sections and control angles. It stands out from the ET6 series due to its three-part exhaust and is predestined for a very high power output. The cylinder can be adapted very well to the desired application via the choice of exhaust. With slight adaptations such as the VMC SeiDue or Kifly 62, outputs of over 30 hp at the rear wheel are possible. However, the performance characteristics are then also correspondingly 'snappy'
.Exhaust cross-section: Ø32mm (oval)
Distance between exhaust studs: 60mmCrushing edge: 1.2mm (+/- 0.1mm)
Tightening torque M6 bolts 10-11Nm, M7 nuts 11-12Nm
SPECIAL FEATURES
As the cylinder was designed for high power output, it has a generous overflow area at the base of the cylinder. A small amount of machining of the crankshaft housing is therefore necessary for installation. This involves removing the crescent-shaped protrusion of the fan wheel tunnel. In order to be able to mount the large cylinder base in the engine housing, the diameter of the latter must be widened. A milling template is included in the kit for this purpose. 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 machined professionally on a CNC milling machine.
