The SXS cylinder head with variable combustion chamber are a must for every racer. The aluminium alloys and optimised 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 spark plug
- SXS CDI unit
- Factory exhaust system
The carburetor jetting must be adjusted to the selected combustion chamber insert and your vehicle model year (e.g. selected combustion chamber insert = Motocross type; vehicle = 125 EXC 09; carburetor jetting to be selected = 125 SX 09). When using the “EXTREME” combustion chamber insert, always select the SX carburetor jetting of your vehicle model year. More information on the carburetor jetting can be obtained from your authorized dealer.
