This, the first ever 350 cc bike deployed in the MX1 World Championship, has already been mastered by factory riders Antonio “Tony” Cairoli and his Red Bull KTM teammate Rui Goncalves. Cairoli not only won the premiere race for the 350 machine; after his GP victories, he is also leading the championship standings. In addition to the unique engine concept, the MX lineup for the 2011 also includes a newly developed frame and chassis components.
As for the SX-F models, the 250 and 350 have the new fuel injection, but the 450 retains the 41mm Keihin carburetor. All SX-F models also get 48mm WP fork up front.
Both the SX and SX-F models have redesigned, stiffer framework, with the only differences arriving from the PDS vs. the linked suspension mounting holes.
As for the two-stroke SX models, all will retain PDS suspension and Keihin carburetors. The 150 and 250 SX models also have the following upgrades:
New cylinder with improved casting
New exhaust pipe with increased wall thickness for more resistance against damage
New radiator cap for better heat stability
Entirely new KTM-patented triple-clamp design that includes a 22mm fixed off-set and overall design improvements for improved flex characteristics and optimal handling.
Modified air box with a new shape that helps reduce dirt and water collection and new TwinAir filter
New brake pads for more progressive feel
New Renthal Diamond handgrips
The 150 SX transmission also received a reinforced 1st gear for durability, and the frame is redesigned with a steeper steering head angle for easier cornering and a better feeling in the front end.
The 2011 models get a new lightweight chrome-moly steel frame KTM says offers higher torsional stiffness and reduced longitudinal stiffness than the previous frame while also absorbing the energy from hard rear wheel impacts.
For the trail entusiasts the EXC range remains largely unchanged, we'll find out more as the new models hit the dealership floors in June.
