Factory cylinder head

The SXS cylinder heads with variable combustion chamber are a must for every racer. The aluminum alloys and optimized combustion chamber shapes employed ensure the best possible heat dissipation. This has a positive effect on power delivery and reduces material wear in the combustion chamber and on the piston. Replacement of the whole head is now no longer necessary - simply put in a new combustion chamber insert and off you go again. To increase the performance of your bike even further, we recommend combination of the SXS cylinder heads with the following parts:

• SXS CDI unit
• Factory exhaust system

Supplied without combustion chamber insert.

IMPORTANT:
When it comes to carburetor jets, we recommend selection of your vehicle's standard jets.
Detailed information about carburetor jets is available from your KTM dealer.
