KTM SXS Factory Engine Kit 250 SX-F/XC-F/XCF-W 07-10
KTM is known for the high performance level of the 250 SX-F engine. One more highlight
for KTM was the 2008 GP season, which was clearly dominated by the orange machines
made in Austria winning the MX2 world championship with Tyla Rattray.
Apart from the KTM factory pilots Rattray and Searle many other riders were able to
finish top 10 or even jump on the podium using KTM SXS bikes. For 2009 the level
of the bikes can even be raised with availability of the KTM Factory-SXS-Kit. Improved
performance, higher rpm level and optimal reliability guarantee top results also for the
2009 race season.
KTM Motorsport has developed a special high-performance crankshaft assembly
by mounting an exclusive extra-light connecting rod into the standard d 250 SX-F
crankshaft made by the race technology specialist PANKL. Ultra-precise machining
and high quality steel can stand the increased rpm level and guarantee less vibrations
and improved reliability.
A special piston pin, developed for Formula-1 engines reduces the friction for improved
performance and better reliability.
Valve spring set
The KTM Motorsport valve spring set includes weight reduced and stronger retainers
and washers, which will stand the increased rpm level achieved in combination with
all other components.
For the 250 SX-F DOHC cylinder head KTM Motorsport developed a perfect racing
approved camshaft combination with optimized camshaft timing for maximal gas flow
and higher overall performance.
When it comes to the clutch nearly all factory teams mount components made by the
American clutch specialist HINSON. Machined basket and inner hub, pressure plate
and a special disc package offer very precise control and maximal reliability.
Includes a machined clutch cover, which offers increased strength and gives a factory
KTM Motorsports 3rd / 4th sliding gear as well as 3rd gear are machined from high
quality Aubert & Duvall steel for highest precision and reliability.
The special KTM Motorsport radiators with enlarged radiation surface and better
efficiency includes hoses and radiator protectors to keep the race engine cool to
assure highest performance in every condition.
Higher rpm and optimal engine efficiency are controlled by the KTM Motorsport CDI.
For the assembly of the kit a complete set of gaskets is included.
