Description
Piston Malossi Testa Rossa FL100
Replacement piston for Malossi MHR FL100 Testa Rossa cylinders.
Malossi pistons are available in different sizes, with size 0 as the smallest size and all other pistons being oversize versions. Each size has an increase of 0.01 mm.
We generally recommend following the manufacturer's instructions (stamped number / letter) when replacing the piston.
Why use oversize pistons?
Although the standard piston (size 0) is completely sufficient, you can further reduce the piston play by using oversize pistons and get even more power from the cylinder. The tighter the piston sits in the bore (thinner oil film, less tilting, less friction), the lower the compression loss, which in turn leads to increased power. Definitely something for savvy tuners and professional use in racing.
Specifications Malossi Test Rossa piston:
- Diameter: 52mm
- Piston pin: 14mm

Malossi Testa Rossa
The Testa Rossa is the latest generation of high-end cylinders from Malossi. The series is the successor to the famous MHR Team, which has long been a reference for scooter tuning and racing. As the name Testa Rossa suggests, the cylinder head is red, which could possibly be interpreted as a small allusion to another famous Italian brand.
The Testa Rossa cylinders represent the state of the art and are extremely powerful. The cylinders were originally introduced with the C-One and RC-One crankcases, but are also compatible with original crankcases, provided they can be machined to fit the new components.
Main features of Testa Rossa cylinders
- 7 transfer ports
- Bridged exhaust
- 1-ring piston
- Two-piece cylinder head with special combustion chamber (improved water volume)
To ensure reliability and top performance, the Testa Rossa must be used with the appropriate tuning components and re-adjusted: reinforced crankshaft (racing or high-end), a suitable tuning exhaust and a larger carburetor and intake.
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.
