Bidalot Racing Factory

Bidalot has been known for 50cc tuning and racing components for several decades. The Racing Factory series (RF WR) includes Bidalot's high-end products and is the brand's most powerful series to date.

The series is available for various displacement classes. The Racing Factory products go to the absolute performance limit in all categories.

Racing Factory range

You can equip your bike completely with Bidalot Racing Factory parts and build yourself a high-end racer. Here is a list with Racing Factory parts:

• Cylinder Bidalot RF WR 50cc to 96cc
• Crankshaft Bidalot RF
• Bidalot RF internal rotor ignition
• Clutch Bidalot RF
• Exhaust Bidalot RF
• Gearbox Bidalot RF
• Spare parts Bidalot RF (gaskets, pistons, clutch plates...)

Of course, you need a bit of know-how to install the racing parts correctly and adjust them to yield maximum power.

To get the full potential out of your engine, we recommend buying a high-quality carburetor with the right diameter for the selected displacement.
Also remember to adapt the chassis to the increased engine power, e.g. with improved brakes and suspension.

Gearbox

A properly geared transmission is a crucial factor in the performance of a motorcycle. You can have the most powerful cylinder, the best exhaust and the greatest tuning parts on the market - if the transmission is not properly geared, too short or too long, you will never get the best performance out of it.

Gearbox Repairs

If you have the necessary know-how you can replace single gearbox parts or the complete gearbox, there is a huge range of options for 50cc motorbikes.

Always remember to maintain the gearbox by changing the oil regularly. You can use gear oil or 4-stroke engine oil (depending on the manufacturer's recommendation).

gearbox Tuning

For 50cc motorcycles, there are complete racing gearboxes whose ratios are designed for tuned setups and where some relevant components are reinforced.

Note: If you can't or don't want to replace the original gearbox with a racing gearbox, you can also change the final ratio by using a different sized front sprocket and rear sprocket.
