The KTM 350 EXC-F is a dual-sport to be reckoned with thanks to its ultra-light chassis and torquey 350 cc engine with a 6-speed PANKL gearbox. Its potent combination of 250-like agility and 450-like power makes it the first choice of riders looking for a class-leadering dual-sport possessing sheer rideability and competitiveness across any terrain.

Engine

Engineered to find the perfect balance of agility, weight, and power, the KTM 350 EXC-F's fuel-injected DOHC engine is set to become a future legend. Its class-leading power delivery and lightweight give it an unbeatable power-to-weight ratio too. A long story short, this is the most perfectly balanced powerplant on the market.

Cylinder head

The KTM 350 EXC-F engine is fitted with a compact DOHC cylinder head for optimal mass centralization while contributing to even better handling. The head configuration, with 2 overhead camshafts controlling the gas flow through the ports, promises outstanding, dual-sport specific engine characteristics. The DLC coated finger followers, as well as the lightweight valves they actuate (intake 36.3 mm, exhaust 29.1 mm), allow for higher engine speeds, a crucial factor in the 350's dynamic performance.

Crankshaft

The KTM 350 EXC-F's crankshaft is located in an ideal position close to the center of gravity, contributing to easier handling. It utilizes a short connecting rod, which makes for an overall compact and lightweight engine with a snappy power delivery. A plain big (bottom) end bearing with two force-fitted bearing shells runs directly on the crank pin. The engine's pressurized lubrication system provides the necessary oil feed for this bearing.

Engine cases and covers

A lightweight engine case design allows for a very centralized shaft configuration while contributing to an efficient centralization of mass. Additionally, the engine covers feature a smart surface structure that reduces the wear caused by the rider's boots, keeping them looking as fresh as the day it rolled off the production line, while a reinforced clutch cover and engine guard mean the engine case is more robust.

Transmission

The KTM 350 EXC-F features a robust 6-speed transmission made by PANKL Racing Systems. The gears are made of a strong, forged raw material, ensuring the highest durability and reliability level. All four-stroke engines are fitted with a gear sensor, giving the option of different engine characteristics for each gear.

Engine management system

The state-of-the-art Keihin Engine Management System, with electronic fuel injection, features a 42 mm throttle body with separate systems for cold starting and idle adjustment. The throttle cable mount also allows for easy access and a smooth routing of cables for crisp throttle response, every time.

Cylinder and piston

Inside the short 88 mm bore cylinder, is an extremely lightweight, forged bridged box-type piston made by CP. Despite its incredibly low weight, it has an extra rigid structure for enhanced durability. Thanks to its lightweight construction, the oscillating masses are low, giving the engine extremely lively characteristics. The compression ratio of 13.5:1 delivers an exceptional engine performance and reduces the risk of engine knocking.

Balancer shaft

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.

Clutch

The KTM 350 EXC-F 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.

E-Starter

The standard electric starter on the KTM 350 EXC-F 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.

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 the frame triangle, features a large center tube for highly efficient coolant flow, as well as radiator fans as standard on all 4-stroke models.

Exhaust

Packing a punch and delivering an unmistakable engine note, all 4-stroke KTM EXC models feature an easy-access two-piece header pipe that can be disassembled easily to allow access to the rear shock. An aluminum muffler sleeve has a short and compact profile.

Frame

All KTM EXC models feature high-tech, lightweight Chromoly steel frames with race-derived geometry, optimal stiffness, and unparalleled feedback for the rider. This translates into a playful handling character, with remarkable stability at speed. The subframe is made of extra-light and ultra-stable aluminum profiles, weighing less than 900 grams providing rear fender stability and durability in the event of a loop out.

Swingarm

The KTM 350 EXC-F features a one-piece aluminum swingarm, which is manufactured using a gravity die-cast production process. This results in exceptional strength at the lowest possible weight and the perfect flex behavior.

Wheels

KTM uses lightweight, CNC-machined hubs and high-end GIANT rims on all EXC models. These guarantee maximum stability and the bare minimum weight, while aluminum spoke nipples feature an innovative design, which reduces the need to continuously tighten the spokes.

Tires

Putting the power to the ground is a set of Continental TKC 80 tires. These provide excellent grip across a variety of terrain, as well as self-cleaning knobs to ensure excellent traction on or off road.

Suspension

For 2022, all KTM EXC models have received a suspension update, with a firmer factory setting focusing on performance and improved consistency across different terrains.
