Thanks to its lightweight construction, the oscillating masses are low, giving the engine extremely lively characteristics. To further improve engine performance, the compression ratio has been increased from 12.3 to 13.5 : 1.
The multifunctional side-mounted counter balance shaft masterfully balances all the oscillating forces, while also driving the water pump. It effectively keeps engine vibrations to a minimum, resulting in the smoothest ride even at the highest engine speeds.
The KTM 350 EXC-F WESS is fitted with the extremely durable, KTM-developed DDS clutch (damped diaphragm steel), with a wear-free steel basket and heat resistant clutch plates. It uses a diaphragm spring instead of the usual coil springs, which results in considerably easier clutch action. Additionally, the Brembo hydraulic system provides easy and precise clutch modulation throughout the entire operating temperature range.
The standard electric starter on the KTM 350 EXC-F WESS uses a proven starter drive and a strong starter motor made by Mitsuba. As demonstrated time and time again, it provides quick and reliable starting, saving you precious time and energy when you need it most.
ALWAYS OPTIMAL COOLING
Maintaining the optimal engine temperature is crucial to ensuring consistent horsepower throughout the ride. The KTM 350 EXC-F WESS features radiators which are mounted close to the center of gravity and match the design of the shrouds perfectly, in order to achieve perfect ergonomics. By using CFD technology (Computational Fluid Dynamics) and a smart coolant circuit routing, the innovative system ensures optimum engine temperature for the highest performance, in all conditions. Above all, the delta distributor, integrated into the frame triangle, features a large center tube, making the coolant flow from the cylinder head to the radiators highly efficient. The radiators have special protectors that protect from flying rocks and debris while also acting as a brace to disperse energy around the radiators in the event of an impact.
FINELY TUNED EXHAUST
When it comes to power delivery and performance, the exhaust plays a key role and packs a punch that is hard to beat. All 4-stroke EXC models feature two-piece header pipes which can be disassembled easily and allow easy access to the shock. The aluminum muffler sleeve has a short and compact profile, bringing the weight closer to the center of gravity for better mass centralization.
The KTM 350 EXC-F WESS features a high-tech, lightweight chromoly steel frames. This includes hydro-formed elements produced by state-of-the-art robot welding. With its race-proven geometries and optimal stiffness, the frame provides great feedback for the rider, playful handling and remarkable stability. The laterally attached engine head stays (the connection between cylinder, head and frame) are made of aluminum, reducing vibration and further contributing to precise cornering. The bikes also feature lateral frame guards with a structured surface, improving grip, while also serving as a heat protector against the muffler on the right side. The subframe is made of extra-light and stable aluminum profiles, weighing less than 900 gr, providing great rear fender stability.

For the first time in a KTM EXC model, the KTM 350 EXC-F WESS machine features the WP XACT air fork, that has already proven its performance in several other Motocross and Offroad racing applications. The new forks offer a wide spectrum of adjustability providing Enduro fans and racers with the latest in suspension technology. It is a 48 mm USD air-sprung fork featuring separate functions in each fork leg, with damping on the right side and the air spring on the left. The left leg features a two-chamber system with a capsuled air cartridge, helping prevent loss of air pressure. Essentially, this means that in the rare case of a leaking outer seal, the internal cartridge pressure keeps the bike in a normal position. The air spring is exceptionally easy to use and can be adjusted to any rider weight via a single air valve and the air pump that is supplied with the bike. The right fork leg integrates a damping cartridge to fit single damping leg requirements and can be adjusted to the track conditions and the rider's preferences. Additionally, the fork top caps have a new design for improved, easy adjustment of compression from top, rebound from bottom (30 clicks each).
The WP XPLOR shock absorber is the key element on the proven PDS rear suspension design (progressive damping system), where the shock is directly linked to the swingarm without an additional linkage system. This keeps weight lower and reduces the chances of hooking on rocks. Optimal enduro-specific damping progression is achieved by using a second damping piston in combination with a closed cup towards the end of the stroke, and supported by a progressive shock spring. The settings on the XPLOR PDS shock provide impressive damping characteristics and match the frame and front-end set-up perfectly. It is fully adjustable, including high and low-speed compression, so you can set the shock up to suit any track, trail and rider preferences.
These high-tech Brembo babies are combined with lightweight Wave brake discs. You couldn't brake any harder or with better feel on an offroad motorcycle.
