Factory cylinder head with variable combustion chamber

The Factory cylinder heads with variable combustion chamber are a must-have for any racer and offer the following properties:

• Cylinder head separate from combustion chamber
• No need to replace the entire cylinder head in case of wear; only the insert needs to be replaced
• The aluminum alloys provide improved heat dissipation and thus improved performance gains

To boost your motorcycle's performance even further, we recommend a combination of the factory cylinder heads with the following parts:

• Factory CDI control unit
• Factory exhaust system

Delivered without combustion chamber insert.

IMPORTANT:

For the carburetor jetting, we recommend using the standard jetting of your vehicle.
