A 250 joins KTM’s Factory Edition fleet, which is significantly improved for 2015.
KTM just took the wraps off two new Factory Edition race motorcycles for 2015. While the KTM 450 SX-F is now entering its fourth year, it, along with the new 250 SX-F (which is making its debut for 2015), represents what KTM is calling “a whole new generation SX model motorcycle.”
What does this mean? Well, KTM says both of these 2015 motocrossers have been developed with weight reduction in mind, and improved mass centralization is designed to help on-track performance. Both engines are designed to be lighter, more compact, and powerful, with cases reshaped for the more centralized rotating mass of the crankshaft and clutch.
This, says KTM, helps reduces the overall length of both powerplants.
In addition to re-worked Keihin engine management with a 44mm throttle body, both engines have new cylinder heads with revised valve trains. The combustion chambers are new, as are the ports, which are shaped for better performance.
What’s more, both of the new Factory Edition KTMs have electronic launch control and five-speed transmissions said to provide “precise and easy” shifting.
