Engine covers for Motorcycles: Essential, Functional, High-Performance

The primary task of cases and covers is to securely enclose the oil and the central components required for engine operation. Of course, not all critical components run in an oil bath, but they still must not be left unprotected against external influences. These parts are therefore protected by appropriate covers.

Crankcase

While in the motocross sector one usually has to contact authorized dealers, there are various types of cases available for 50cc gear bikes.

For simple repairs according to manufacturer specifications, you can opt for standard crankcases. If you want to tune your bike for racing use, we offer cases from renowned brands such as Top Performance or Metrakit.

For Derbi and Minarelli AM6 engines (Rieju MRT, Beta RR, Sherco SM, Fantic, etc.), we stock 100% original OEM parts, affordable aftermarket versions in OEM quality, and the well-known FL housings (Flange Mount). The latter were specifically developed for mounting modern high-end racing cylinders, such as the Stage6 R/T FL or the TPR Factory FL 100.

Clutch Covers and Other Covers

In many cases, a complete crankcase is not necessary, as there are other covers available.

If your sealing surfaces are in good condition and you simply want to refine the aesthetics, improve strategic details, or give the engine a like-new look, we have all the right components in stock: ignition covers, clutch covers, water and oil pump covers, sprocket guards, and much more. We carry parts from well-known manufacturers for Derbi and AM6 engines as well as for the most popular motocross models (Yamaha YZ, Honda CRF, KTM EXC, Husqvarna...).

We stock brands such as Stage6, STR8, Doppler, Voca Racing, KRM, Hinson, Boyesen, Rekluse, Moose, and many others.

Pro Tips

Please note that replacing some cases requires special tools (e.g., flywheel pullers or crankcase splitters), which we also offer in the shop. Working with improper tools risks damaging the sealing surfaces, which can lead to leaks.

Thoroughly clean every part with a degreaser before installation.

Also, make sure to get new gaskets and, if necessary, suitable sealant! It would be frustrating to have to disassemble everything again just because you saved on a small gasket, wouldn't it?

Finally, use high-quality operating fluids (gear oil, coolant) to provide optimal protection for your newly assembled components.
