Polini Torsen Rear Axle for Piaggio
Polini offers this reinforced rear axle specifically for the Torsen control arm on Piaggio NRG and Zip Sp2 models manufactured in 1998 or later.
The design is the result of months of collaboration with the top riders in the Polini Cup. The product is made of a reinforced alloy to ensure perfect stability when cornering.
NOTE: For Piaggio models from 1998 onward, sold without the transmission gear!
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.
