The factory 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 combining factory cylinder heads with the following parts:
Factory/SXS spark plug
Factory/SXS CDI
Factory/SXS Pipe and silencer
IMPORTANT: The carburetor jets must be matched with the selected combustion chamber insert and the model year of your vehicle (KTM: e.g. selected combustion chamber insert = motocross, vehicle = 250 XC-W MY 09 --> appropriate carburetor jets = 250 SX MY 09)(HQV: (e.g. selected combustion chamber insert = type Motocross, vehicle = TE 250 MY 14 ➝ appropriate carburetor jets = TC 250 MY 14). Detailed information about carburetor jetting is available from your dealer.
