Cylinder Gasket Set Malossi Testa Rossa FL100 for Malossi RC-One

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.

what does a gasket do?

There are many different types of gaskets or gasket sets in an engine, e.g. cylinder gaskets, intake gaskets, oil seals, crankcase gaskets, exhaust gaskets, carburetor gaskets or engine gasket sets. They all have the same function: to prevent leakage between components.

When and why should you change an engine gasket?

When servicing your two-wheeler or noticing leaking fluids, be sure to follow this one important rule: Always replace an old gasket with a new gasket.
Damaged or worn gaskets can no longer do their job properly, the parts that have to be sealed are no longer adequately sealed, which can lead to serious follow-up damages.

Before you install a new gasket, you must thoroughly clean and degrease the sealing surface.

You can also use silicone sealant as an alternative to paper or metal gaskets in some cases. But beware, O-rings and oil seals cannot be replaced by sealant.

Tuning Level: High End 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.

High End Racing products are exclusively designed for racing and should only be handled by tuning pros with the appropriate technical know-how. High-end racing parts often require modifications or machining of certain elements to accommodate the often larger components (larger crank webs, larger intake, etc.). Whether you stick with 50cc or increase the displacement, high-end racing parts offer much higher performance than the original parts and are the most powerful tuning parts.

Note: To ensure the reliability of the engine, it is important that the parts are compatible and that you do regular maintenance on your two-wheeler.

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.
