2012 KTM 65SX

The 2012-KTM-65SX is the right sports machine for all up-and-coming riders. With a six-speed transmission, generous suspension travel & high-quality parts, the mini-crosser provides everything necessary for having plenty of fun & laying the foundation for a promising MX career. Its incomparable peak power & fully adjustable suspension parts reinforce its claim to being number.


2012-KTM-65SX-Engine with PCEV : The two-stroke engine on the 65 SX excels, thanks to its PCEV (Pressure Controlled Exhaust Valve) exhaust control system, with a great deal of torque from the bottom end up and a very linear power delivery makes this bike very easy to ride. Consistent high performance is ensured by the cooling circuit featuring integrated crankcase cooling.

2012-KTM-65SX-Frame and suspension components : The completely redesigned upside-down telescopic fork from WP Suspension with 220 mm (8.66 in) suspension travel and the WP shock absorber provide adjustable compression and rebound damping. The stable steel frame on the 65 SX has a bolted-on, light alloy subframe. The newly developed, fully adjustable WP telescopic fork is generously dimensioned with 35 mm (1.38 in) outer tubes and the anodized handlebar from Renthal are manufactured from a high-quality aluminum alloy. Standard equipment also includes a hydraulic clutch and braided steel brake lines. KTM has spared nothing on the 65 SX.

2012-KTM-65SX-Brakes : The front brake on the 65 SX has been further refined and now provides an even better pressure point thanks to the new, stiffer 4-piston brake caliper. The action of the brake lever has been even better adapted to the requirements of young racers in favor of finer controllability and more efficient force transmission. Four-piston brake calipers and wave type rotors at the front and rear only the highest-quality components are used on the 65 SXs Formula brake system. Aluminum spoked wheels and the nickel-coated exhaust system round off the image of a best-equipped mini-crosser with a first-class finish.
