MVT S-Race Crankshaft
We are constantly extending our catalogue and trying to make new, interesting products available to you - MVT Crankshaft "SRace" Derbi Euro 3 (D50B0).
It is a full-circle crankshaft meaning that primary compression in the crankcase is increased which in turn means more torque. The connecting rod is polished, this gets rid of stress risers and reduces premature breakage. The balancing is much more precise than on a stock crankshaft so your engine will run smoother, especially at high rpm, and is more reliable.
Suitable for up to 15,000rpm. We recommend using it with sports or racing engines.
Main bearings and oil seals are not included, sold separately.
For Derbi Euro 3 (D50B0) engines - 12x16x16mm small end bearing (included).
Note: for use with MVT 50cc cylinder, please use a 12x16x13mm small end bearing.
How to change a crankshaft?
The crankshaft is one of the main components of the engine and is responsible for the smooth operation of motorcycle, scooter and moped, whether with two-stroke or four-stroke engine. The longevity of the engine depends not only on the proper condition of the crankshaft, but also on the fact that it is properly mounted.
For a correct installation of the crankshaft, we recommend our tutorial: Crankshaft disassembly and assembly.
How can I tell if my crankshaft is Damaged?
A broken crankshaft causes metallic noises, unusual vibrations, leaking oil seals and drastically reduces the performance of the two-wheeler. In any case, the vehicle must be stopped immediately to prevent the damage from getting worse.
Please note that whenever the crankshaft is changed and serviced, you'll have to install new crankshaft bearings.
Tuning Level: Racing
We categorize our products into different performance levels Original, Sport, Racing and High End , so that our customers can choose the right parts for their setup. It is really important to combine parts that belong to the same tuning level, this is especially true for cylinders, crankshafts and exhausts.
Racing products are designed for a more extreme uses and are developed primarily for racing. Whether you stay at 50cc or increase the displacement, the corresponding Racing parts produce much higher performance than the original parts in order to achieve maximum power.
