Description

Here is the very latest high engine, RF70WR, for DERBI E2 5EBS50 engine. Unquestionably the most powerful kit on the market in normal racing for the DERBI EURO 2 engine!

This high engine is designed to be fitted with a racing crankshaft and connecting rod length identical to the original. However, because of its very high performance, we recommend fitting an excellent, well-reinforced crankshaft.

Entirely modeled in 3D CAD, the cylinder sees its water chamber go around all the transfer and exhaust cores, with constant thicknesses, able to guarantee great dimensional stability of the cylinder, due to optimized cooling.

The cylinder head, heat-treated, is also equipped with a water chamber, surrounding the combustion chamber, for good heat dissipation and perfect cooling. It is self-centering in the cylinder, and fits 2.4mm into the bore on this version.

The fixing of the specific exhaust flange is ensured by 4 screws. However, it is possible to mount a fixing flange with 2 holes, with a center distance of 48mm.

You will find, sold as accessories, exhaust flanges of different sizes, allowing the adaptation of almost all pots on the market. These flanges are available in the following dimensions:

Ø28mm x L30mm

Ø30mm x L30mm

Ø32mm x L30mm

Technically, this thermal group is composed of:
