Notes and Safety

Top Performances TPR

The TPR series from Top Performances comprises relatively high-quality parts from the Italian tuning brand.

The TPR tuning parts for 50cc scooters and motorcycles with high performance can be categorized as racing parts, e.g:

  • Aluminum cylinder with 1-ring piston
  • Air filter
  • Scooter and maxi scooter CVTs
  • Reinforced clutches for 50cc geared mopeds
  • Reinforced crankshafts
  • Tuning reed valves
  • Open CDIs

The TPR catalog is constantly being expanded to satisfy demanding riders and tuning fans looking for quality and performance in the future.

When to replace the piston?

To find out when the piston on your motorcycle, scooter or moped needs to be replaced, it's best to check your bike's manual. You can also keep an eye out for certain symptoms such as loss of compression, loss of power or oil consumption (only for a four-stroke piston).

Extending Piston life

To extend the life of the piston and reduce cylinder wear, it is recommended that you replace the piston rings on an alternating basis. This method maximizes piston life and improves engine performance.

It is important that you replace cylinder gaskets and piston circlips each time you disassemble the cylinder and piston. Failure to do so can result in oil leaks and engine damage.

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.

Aluminium cylinders

Aluminium cylinders are more powerful than cast iron cylinders, but require more regular maintenance and must be combined with different components such as a reinforced crankshaft and a larger carburetor.

How to run in an aluminium cylinder?

Aluminium cylinders should be run in for about 200 kilometers , and you should use a fully synthetic engine oil.

Note: To ensure optimum performance and reliability, it is advisable to measure the squish clearance. Just have a look at our tutorial How to adjust squish clearance.
