2012 KTM 65 SX


Just a shade above the 50 SX in KTM’s pecking order for upstart dirt bikes is the 65 SX . Whereas the former caters to the little tikes, the latter is just the right sports machine for all up-and-coming riders from 8 to 12 years of age and up to a height of about 1.60 m (5.25 ft).

The design of the bike is relatively simple and easy-to-use, something that kids will have a good time with while not worrying about all the complicated trinkets that adult bikes come with. On top of that, the 65 SX boasts of an impressive 65cc two-stroke engine that excels, thanks to its PCEV (Pressure Controlled Exhaust Valve) exhaust control system, with a great deal of torque from the bottom end up and very linear power development, making it correspondingly easy to ride.

The 65 SX’s engine is mated to a six-speed transmission, and when combined with a generous suspension travel and high-quality components, the mini-crosser provides everything necessary for having plenty of fun and laying the foundations for a promising MX career.

In terms of its handling characteristics, the 65 SX features a newly developed, fully adjustable WP telescopic fork that is generously dimensioned with 35 mm outer tubes. The anodized handlebars from Renthal are manufactured from a high-quality aluminum alloy. Likewise, four-piston brake calipers and wave discs have been fitted at the front and rear of the bike while aluminum spoked wheels and the nickel-coated exhaust system round off the image of a mini-crosser that kids will undoubtedly enjoy.

Engine

KTM 65 SX

The 65 SX’s two-stroke engine excels, thanks to its PCEV (Pressure Controlled Exhaust Valve) exhaust control system, with a great deal of torque from the bottom end up and very linear power development, making it correspondingly easy to ride. Consistently high performance is ensured by the cooling circuit featuring integrated crankcase cooling.

Brakes

KTM 65 SX

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 kinematics of the brake lever have been even better adapted to the requirements of young racers in favor of finer controllability and more efficient force transmission.

Frame and Suspension

KTM 65 SX

The newly developed, fully adjustable WP telescopic fork is generously dimensioned with 35 mm (1.38 in) outer tubes and the anodized handlebars 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.

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 65 SX’s stable steel frame has a bolted-on, light alloy subframe.
