2014 KTM 85 SX: THE LITTLE BIG ONE
WHEELS AND BRAKES
BRAKES
The Formula brake system with radial brake calipers - four pistons in front, two in the rear - with lightweight Wave brake discs - front 220mm, rear 210mm - are the reference in terms of controlled action and braking performance. In 2014, a revised front master cylinder with improved piston system is used, which provides even better durability.
WHEELS
The wheels use lighweight, CNC-machined hubs, high-end Excel rims and black coated spokes with lightweight aluminum nipples to ensure the highest stability at minimum weight. The OEM Pirelli tires are distinguished by perfect traction and outstanding performance.
UNRIVALED POWER
ENGINE
Cutting-edge 2-stroke technology combined with a precise 6-speed gear box and hydraulic clutch are the foundation of the 85 SX's superiority in all amateur racing series.
CRANKSHAFT
Thanks to its perfectly sized lightweight con rod, the crankshaft is distinguished by minimum vibrations an maximum durability.
AIRBOX
What is good for the bigger KTM offroad bikes, cannot be bad for the 85 SX: air filter change within seconds without tools.
CYLINDER
The high-performance cylinder with flow-optimized ports and a high-precision exhaust control valve provides the engine with its unrivaled peformance.
CLUTCH
New in 2014, the hydraulic clutch mechanism by Formula ensures an easy clutch action and well-defined modulation.
COOLING
A constant temperature balance for consistent, high-performance is ensured by an intelligent cooling circuit with integrated crankscase cooling and two radiators.
STABLE IN EVERY SITUATION
HANDLEBAR
The 85 SX is has a super-strong, tapered Renthal handlebar made of high-quality aluminium alloy whose bend is perfect for motocross requirements.
GRAPHICS
The revised, cool graphic design provides a striking new look.
BODYWORK
Ergonomics and fuction of the bodywork is designed in such a way as to achieve complete harmony between rider and bike.
FRAME
Made of top-quality chromoly steel with a lightweight, bolt-on aluminum rear subframe, the frame ensures maximum stability at minimum weight. It has a rugged polymer coating in a classy charcoal grey metallic.
MASTERS THE TOUGHEST TRACKS
SUSPENSION TRAVEL AND DAMPING
Up front, there's a 43mm upside down fork with 270mm of travel, while a revised PDS monoshock on the rear now provides even better traction and optimum surface contact. Both are made by renowned supplier WP Suspension. Of course, rebound and compression damping can be adjusted separately for a quick and precise set-up to match the track and rider.
CHASSIS
The proven 43mm upside down fork with 270mm of suspension travel and the rear PDS monoshock ensure optimum traction and suspension comfort on the KTM 85 SX. Rebound and compression damping can be adapted individually to track and rider.
The KTM 85 SX is the prime choice for future champions. As the minicycle class leader, the 85 SX features the most powerful engine in the field housed in a lightweight, stable chassis. For the highest level of amateur competition, the 85 SX is the clear choice.
