Tuning Kit cylinder + crankshaft + exhaust 50cc MVT G1 S-Race MBK 51

Tuning Kit cylinder + crankshaft 50cc MVT G1 S-Race MBK 51. We assembled some of the main components of the S-Race series from MVT as a kit. Cylinder, exhaust and crankshaft work perfectly together and in combination lead to a considerable power increase for your 50cc classic moped.

The pack includes:

• Aluminium cylinder kit 50cc MVT G1 S-Race MBK 51
• Exhaust MVT SP2 S-Race MBK 51
• Crankshaft MVT G1 S-Race MBK 51
• Crankshaft bearings + oil seals reinforced C3 polyamide cage MBK 51 / 88

The S-Race cylinder is a high performance tuning cylinder made of aluminum, with 6 transfer ports and anexhaust with boost ports. It comes with a 1-ring piston and a cylinder head (High Compression). You will notice the increase in performance especially in the higher rpm range.

The S-Race exhaust (with fantastic looking red silencer) is the perfect match for MVT's S-Race cylinders, with wide powerband and strong performance, for improved acceleration and higher top speed. The flange is adjustable, so that optimal alignment of cylinder and exhaust can be achieved and you have some wriggle room for fine tuning, as you can shorten or lengthen the exhaust tract a bit.

To match: a S-Race full circle crankshaft, which provides better torque thanks to increased pre-compression in the engine case. The balancing is extremely precise, which leads to smooth running even in the higher rpm range. The crankshaft is very robust and resilient and can also be used for racing / endurance racing.

We also included matching crankshaft bearings + oil seals. The bearings with polyamide cage can withstand very high rpms and can be used for racing setups.
