Cylinder Stage6 Sport 50cc MK2 Derbi Euro 3 / 4

Sport 50cc MK2 cylinder for Derbi Euro 3 and Euro 4 engines from the manufacturer Stage6.

A 50cc sport cylinder made of aluminium with a high-strength Nikasil coating, the cylinder was developed for everyday use and is therefore approved for road use.

In terms of performance, the Sport MKII easily reaches the top of comparable sports models. The shape of the transfers results in a good filling and its exhaust with boosters facilitates the exhaust gas outlet. The generous degrees of distribution (118° - 181°) offer a wide range of use and guarantee optimised engine characteristics and a lot of riding pleasure over a wide rpm range.

To ensure maximum reliability, Stage6 has opted for a 2-ring piston. The use of 2-ring pistons slightly reduces the cylinder performance, but increases the service life of the cylinder.

To get the most out of this Stage6 MKII Sport 50cc cylinder, the manufacturer Stage6 recommends combining it with a 21mm carburettor and a Stage6 Streetrace or Voca Rookie exhaust.

The kit includes:

• 50ccm cylinder with 40mm bore made of aluminium with 5 transfers (intake) and 1 exhaust outlet with boosters.
• 2 ring piston.
• One-piece high compression aluminium cylinder head
• Gasket set (base and head gaskets)

Attention: If your crankshaft has more than 5000 km on it, we recommend that you replace it with a new reinforced crankshaft.
