Kit 50cc high engine Ø40mm DR Racing cast iron DERBI euro 1 & 2

Approved on public roads! Respects the capacity of 50cc.

Here are the best value on the market! This kit rolls / piston / cylinder head DR Racing is a top engine replacement of cast iron, it is much more solid than the original which did not prevent it from being relatively efficient. Its diameter is 40mm so it develops the limited capacity of approximately 50cc.

The channels are reworked, the flowcharts are slightly increased, the cylinder head has a hemispherical combustion chamber high compression. We all regret as this room is not polished but blasted and painted. The cylinder is made ​​with a cast iron treated minacrom which makes heavy duty!

The piston is a model Bi segment in METRAKIT with a segment L. This piston has the same side nipples! In short this little kit is a great alternative model that shoed you slightly improve performance for a class price!
