NIMBLE OFFROAD MASTER
The KTM 125 XC is the most compact and lightweight of the full-size Cross-Country machines – but don’t let that fool you – it’s a fighter bar none. Making use of a lightweight Cross-Country specific chassis and the most competitive 125 cc 2-stroke engine in the class, the 2022 KTM 125 XC delivers superior agility and power to fulfill the demands of any young and aspiring Offroad racer. This 2-stroke screamer is the ultimate entry point into the pro Offroad ranks, with factory looks to boot.

Motor og Eksos
Featuring one of the most competitive and powerful engines in the 125 cc class, now also features a refined gearing of 13:50, giving the 2022 KTM 125 XC improved response out of corners. With an outstanding power-to-weight ratio, low cost, electric start, and overall simplicity, the KTM 125 XC remains a firm favorite in the cross-country paddock. The compact and durable engine was developed using the latest KTM engineering know-how, resulting in broad power across the rev range. Its easy rideability and outstanding performance are benefits that equate to better race results.
transmission
The KTM 125 XC is makes use of a robust 6-speed semi-close transmission features gear ratios perfectly in sync with the 125 cc powerplant’s powerband. An advanced ´No Dirt´ gear shift lever design prevents mud and sand from jamming the joint of the lever and guarantees trouble-free shifting.
exhaust
There’s more to it than ‘braaaap!’. The exhaust plays a key role in packing that signature 2-stroke punch. When it comes to power delivery and performance, the exhaust is developed specifically for the KTM 125 XC and plays a key role in packing a punch. In addition, its special shape provides slimmer ergonomics while still […]
cylinder
At the heart of the 125 cc engine is a cylinder with a 54 mm bore. Making use of a power valve unit with a sophisticated mechanism with lateral support exhaust ports, it increases engine performance, while the upper contour of the exhaust port has been machined to ensure more accurate port timing. The two-component […]
crankcases and engine covers
These compact engine cases are manufactured using a high-pressure die-cast production process which helps with weight reduction but maintains strength and durability. This design also allows for optimal shaft arrangements close to the center of gravity, resulting in ideal mass centralization and ride-ability.
cooling
Keeping the engine cool when the going gets tough comes courtesy of a pair of radiators, mounted close to the center of gravity. These make use of CFD technology (Computational Fluid Dynamics) and clever coolant circuit routing, achieving optimum engine temperature for the highest performance, in all conditions. Above all, the delta distributor, integrated into […]
carburetor
The KTM 125 XC is fitted with a MIKUNI TMX 38 mm flat slide carburetor. Featuring latest technology reed blocks for the intake it offers optimal function, sealing and reliability, ensuring the whole system is always providing smooth and controllable power throughout the rev range.

Chassi
The KTM 125 XC is built around a high-tech, lightweight chrome-moly steel frame, which provides class-leading levels of handling, rideability, precision, and stability. Designed to take the hardest of hits, the frame itself acts as a shock absorber for the front and rear suspension, soaking up any jumps and jolts. The frame also features an extra-light subframe made of aluminum, which tips the scales at less than 2 pounds, keeping the weight low and the speed stellar.
wheels
The KTM 125 XC is fitted with a lightweight set of high-end wheels, consisting of CNC-machined hubs, Giant rims, and black spokes with aluminum nipples. These are wrapped in Dunlop Geomax AT81, which together, provide maximum, grip, traction, and stability with the absolute and minimum weight.
triple clamp
High-quality, CNC machined triple clamps keep the handlebars in check via rubber damped fixtures. These also allow for two positions of adjustment, with a handy hour meter fitted alongside so that you know when it’s time to give your machine a little TLC.
sweengarm
The cast aluminum swingarm design offers low weight and perfect flex behavior, perfectly complimenting the frame. And being a single-component casting, it eliminates any inconsistencies and inherent weak points created by welding, making it stronger and better looking.
rear suspension
Big bumps beware – the WP XACT shock absorber has been developed with the entire frame and swingarm architecture in mind, including the linkage system and the WP XACT front forks. It also features machined and anodized components, making it a truly impressive piece of equipment to look at too.
fuel tank
The KTM 125 XC has a lightweight, see-through polyethylene tank with a capacity of 2.4 gallons. A quick-release filler cap makes for easy and reliable closure. And don’t worry about when the gas starts running thin – the aforementioned clear tanks mean you’ve always got an eye on the fuel level.
front suspension
The KTM XC range features the same 48 mm USD air-sprung WP XACT front forks with AER technology as found on our championship-winning motocross bikes. These are a split fork with separate functions for each leg. That means damping functions are on the right side, whereas the air spring is on the left. This left […]
brakes
When it comes to bringing this machine to stop, you’ll be happy to have high-tech Brembo brake calipers and lightweight wavy discs doing the business. These also take years of competitive racing into account, providing the perfect combination of ideal pad density and steel quality for longevity and consistent feel.
air box
The easy-access airbox on the KTM 125 XC ensures optimal flow dynamics, thanks to specially designed intake snorkels. This means air is force-fed into the motor, resulting in the perfect balance of power and throttle response. Keeping the air clean, is a large Twin-Air air filter fitted to a rigid cage for ideal placement at […]

Ergonomi og komfort
All KTM XC models are equipped with adjustable, high-strength aluminum tapered handlebars made by NEKEN. These can be mounted in four different positions. Standard with ODI vulcanized grip on the right side and a comfortable ODI lock-on grip on the left, your only worry is hanging on, and letting rip.
seats
A slim, factory-inspired blue seat finished with grip ribs for improved rider connection and provides the ideal combination of comfort and control.

Bodywork og dekaler
The 2022 KTM XC Range receives a distinctive visual update, taking the bike even closer to the RED BULL KTM FACTORY RACING look, with a new blue seat and the distinctive motorsport finishing touch; the orange frame.

Programvare og elektronikk
KTM EXC TPI models feature the most modern engine management system of any 2-stroke off-road motorcycle. By reading various sensor data inputs, such as intake and ambient air pressure, throttle valve position and water temperature, the control unit optimizes ignition timing and the amount of fuel to inject at all altitudes and conditions.
BATTERY & WIRING HARNESS
All engines are fitted with the proven electric starter, which is a major benefit for any offroad activity. It is powered by a super lightweight 2 ah lithium-ion starter battery which provides safe, reliable starting. A reworked wiring harness and revised packaging has most of the electrical components concentrated into a common area below the […]
