Here is the original type 50cc aluminum kit from P2R , this cylinder with its stud cylinder head (can be broken down into 2 parts) will be installed with your DERBI euro 3 and 4 engine. This high engine is in chrome-treated aluminum and very good quality. It comes complete with its cylinder head and gaskets, it has a two-segment piston.
It does not offer much more performance than a real original DERBI because it only has a high compression stud cylinder head for improvement. This model has an incoming chamber, this means that the chamber does not shift from the cylinder during assembly. The chamber is truncated with a polished finish. This cylinder is truly excellent value for money.
Remember that aluminum offers better heat dissipation, but also better expansion, less friction… than a cast iron cylinder. An excellent compromise to start fresh.
The pack contains:
Cylinder
Two-segment piston
Cylinder head
Segments
piston pin
clips
attached package
As an option we offer you a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement of the piston and the lower skirts is also included in this modification. Count a little extra time for this preparation!
