All 2-stroke models feature a new CDI control unit with an advanced hardware which improves the starting behavior of the engine. The ignition curves remain unchanged.

EXHAUST

The exhaust system has been designed to perfectly match the engine’s power characteristics and contributes to the outstanding all-round performance and ride-ability. The header pipe is using a 3-dimensional stamping process. Once the components have been shaped, they are robot welded to ensure the highest level of quality, consistency and durability. The lightweight and compact […]

CYLINDER

The cylinder on the 2019 model has a bore and stroke of 47/48.95 mm. It features a sophisticated power valve system, which controls both the exhaust valve and the sub exhaust ports, giving the bike excellent torque, power and power delivery. This translates to significant midrange performance, reducing the need to overwork the clutch in […]

CRANKSHAFT

The KTM 85 SX features a lightweight crankshaft with optimized balancing for reduced vibration and oscillating mass. As light as the crankshaft is, the rotational inertia has not been compromised, ensuring maximum torque and revs, as well as easy ride-ability.

CRANKCASES AND ENGINE COVERS

The crankcases are manufactured using a high pressure die-cast production process, keeping wall thickness to a minimum while retaining strength and durability. The design of the cases is very compact and aims at positioning the shaft arrangements as close as possible to the center of gravity, contributing to better handling.

COOLING

Maintaining the optimal engine temperature is crucial to ensuring consistent horsepower throughout the ride. The KTM 85 SX features newly designed radiators which are mounted 12 mm lower than the predecessors. This lowers the center of gravity and matches the design of the new shrouds perfectly, in order to achieve perfect ergonomics. By using CFD […]

CLUTCH

The KTM 85 SX features a strong and reliable clutch. It allows for an extremely compact design and also contributes to an outstanding durability. The clutch is easily actuated by the Formula hydraulic system, which also ensures play is always compensated for, keeping the clutch point the same throughout the ride and under all conditions.

CARBURETOR

The KTM 125 SX is fitted with a MIKUNI TMX carburetor. This 38mm flat slide carb lives to provide smooth and controllable power all the way up to the rev limitation. With a new intake manifold the carburetor is turned 7° in order to reduce the overflow of fuel. And it’s less sensitive to different […]

Chassi

Chassi

For the 85cc, KTM has successfully developed a chassis that not only handles the hard charging brutality of a 15-year-old, but also effectively accommodates a lightweight newcomer to the class. This is effectively achieved through its lightweight, high-tech steel frame. It has optimized flex characteristics that provide a great feeling for the rider and help to soak up those big hits, while also delivering excellent agility and high-speed stability. Every element is designed to work in perfect harmony and contributes to an intuitive ride like no other.

WHEELS

Black Excel rims and CNC-machined hubs ensure the strongest base of forward momentum on the KTM 85 SX. Maxxis tires have been fitted to deliver exceptional straight-line stability and excellent traction on a wide variety of terrain, ensuring the power ends up where it is intended – on the ground.

SUBFRAME

Made from lightweight aluminum, the new subframe features a shorter and more compact profile. It is now 75mm shorter and 0.2kg lighter, which not only contributes to the overall weight reduction but also improves mass centralization.

REAR SUSPENSION

The KTM 85 SX features a WP Xplor PDS (Progressive Damping System) rear shock absorber. The design offers a high progression rate and excellent response. It provides the wheel with a total of 305 mm of travel and is fully adjustable for preload, compression and rebound.

FRONT SUSPENSION

The KTM 85 SX front fork features the same suspension technology found in the full-size motocross range. The WP AER 43 consists of a split fork design with a capsuled air spring in the left leg and the trusted oil damping system in the right leg. It offers a significant improvement in suspension performance with […]

FRAME

The frame on the KTM 85 SX is a scaled down version of the championship-proven full-size frames. It is professionally crafted using hydro formed Chromium Molybdenum steel tubes that are robot welded, ensuring the highest levels of consistent quality. The flex characteristics have been specifically tailored for easy handling and optimal comfort, while working in […]

BRAKES

The KTM 85 SX features the Formula brake system with radial calipers – four pistons in front, two in the rear – with lightweight Wave brake discs – front 240 mm diameter, rear 210 mm. The system is the benchmark in terms of controlled action and braking performance, ensuring powerful and confident braking.

AIRBOX

The KTM 85 SX airbox is designed to optimize the small space available to deliver the best possible performance, while still maintaining the highest level of filter protection. The air filter is esily accessed, without tools, by removing the left side panel. Knowing that air literally breathes power into the motor, KTM has ensured that […]

Ergonomi og komfort

Ergonomi og komfort

85cc riders come in all shapes and sizes and require intelligent motorcycle design to deal with their wide range of dynamics. For optimal high-performance ergonomics, KTM used the proven design of the big bike range on the KTM 85 SX. The goal was to provide a neutral riding position that, together with perfectly shaped bodywork, offers the best rider comfort and maneuverability. A rider’s main interaction with the motorcycle comes through the seat, footpegs and handlebars, which is why KTM has used the best quality parts in these areas. The placement of these crucial contact points is also vitally important for balance and control and, through various handlebar position options, can be adjusted to suit a rider’s preference. This ensures the optimal riding position for race-winning performance.

HANDLEBAR

The KTM 85 SX features a strong, lightweight tapered aluminum handlebar, with a specifically shaped bend to suit the overall ergonomics. Additionally, the bike comes standard with ODI lock-on grips, which include a vulcanized grip on the right side and a lock-on grip on the left, which does not require glue or wire for mounting.
