2012 KTM 65 SX, The KTM 65 SX is just the right sports machine for all up-and-coming riders. With a six-speed transmission, generous suspension travel and high-quality components, the mini-crosser provides everything necessary for having plenty of fun and laying the foundation for a promising MX career. Its unrivalled peak power and fully adjustable suspension components reinforce its claim to being number one.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.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.Four-piston brake calipers and wave type rotors at the front and rear ‿ only the highest-quality components are used on the 65 SX's 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.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.
