The all-new SXS two-stroke cylinder heads are a must for the serious racer and two-stroke tuner.
With variable combustion chamber options designed for specific power output and delivery, every rider
can find the SXS cylinder head they need! 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 spark plug
– SXS CDI unit
– KTM PowerParts exhaust system
IMPORTANT:
The carburetor jets must be matched with the selected combustion chamber insert and the model year
of your vehicle (e.g. selected combustion chamber insert = motocross, vehicle = 250 XC-W MY 09 -->
appropriate carburetor jets = 250 SX MY 09). Detailed information about carburetor
jetting is available from your KTM dealer.
