Kit 50cc liquid without cylinder head DOPPLER Racing aluminum mbk 51 / motobecane av10

New for 2020 from DOPPLER . The famous cylinder DOPPLER Racing liquid LC for MBK 51.

This small 50cc liquid-cooled kit has a top-of-the-range mono-segment piston with side greasers, the cylinder is of good quality, in nicasil-treated aluminium.

6 intake transfers with booster exhaust, it is taken directly from real competition cylinders. It is the best 50cc kit for MBK 51 on the market. It has a relatively correct price!

Its diagrams are not extremely high, which will allow it not to require a very greedy configuration, a good little 15mm PHBG to 19mm PHBG or even CP from polini with 0.35mm valve slats, an exhaust (ER1 doppler highly recommended) and a good drive that uses the right power regime and it will be perfect.

Doppler recommends fitting a BR10HIX spark plug and running in for 300 km with a 100% synthetic oil of course.

As an option, we offer you a stage 1 preparation, this preparation is a modification of the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the bottom of the skirt is also included in this modification. Count a little extra time for this preparation!
