The most efficient 50cc liquid cooling kit for your MBK 51.
New for 2020 from DOPPLER . The famous DOPPLER Racing liquid LC cylinder for MBK 51 with its cylinder head.
This small 50cc liquid cooling kit has a high-end single-segment piston with side grease nipples, the cylinder is of good quality, in nicasil treated aluminum.
6 intake transfers with booster exhaust, it is taken directly from real competition cylinders. This is the best 50cc kit for MBK 51 on the market. It has a relatively fair 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 ( MVT S-RACE highly recommended ) and a good variator which uses the right power regime and it will be perfect.
This complete version comes with a high compression cylinder head with bi-hemispherical chamber, mass machined / anodized!
Doppler recommends the installation of a BR10HIX spark plug and a running-in period of 300 km with 100% synthetic oil of course.
As an option we offer 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. Allow a little extra time for this preparation!
Mounts on:
