KTM 300 EXC TPI 2018

Chassis

KTM engineers just love dropping weight year after year. The result: the 2018 KTM EXC models are the slimmest, lightest dirt bikes out there.

Chassis
Frame

The high-tech, lightweight chrome-moly steel frame has a knack for easy handling, outlandish rideability, precise cornering and excellent stability. You can also count on high torsional rigidity and low longitudinal stiffness. This results in better absorption of the energy created from the front and rear suspension sucking up jumps and bumps. In short: more comfort and less rider fatigue. Laterally attached, lightweight engine head stays (the connection between cylinder head and frame) contribute to a reduced vibration level. Two threaded inserts in the lower cradle tubes allow for safe fixation of an optional skid plate. The engineers could pull off all that, while making their frame a big fat kilogram lighter than that of the lightest competitor on the market. In addition, it is easier to maintain, easier to work on and supplies more space for the tank and other components. On the EXC TPI models the upper frame tube features a slot where the oil filler cap is mounted, which feeds the oil tank via a hose inside the frame tube. The bike also features an extra-light subframe made of stable aluminum profiles, which tiptoes the scales at less than 900g.

Swingarm

The cast aluminum design offers low weight and a perfect flex behavior. The single-component casting process eliminates any inconsistencies and inherent weak points created by welding. It’s better looking too.

Wheels & Suspension

Wheels

The EXC wheels feature lightweight, CNC machined hubs and high-end Giant rims guaranteeing maximum stability at minimum weight. The wheels are fitted with MAXXIS tires – perfect for surefooted performance off-road and stability on-road.

Front suspension

The WP XPlor 48 upside-down fork is a split fork developed by WP in close collaboration with KTM. It is fitted with a spring on both sides but features separated functions for each fork leg: compression damping is fitted on the left side, while rebound is on the right. The forks can easily be adjusted for compression and rebound with the twist of a dial on the top of the forks. New outer fork tubes and a reworked setting make for more sensitivity, improved damping behavior and a reduced weight. In addition, a sealed hydro-stop guarantees excellent resistance to bottoming-out. Due to high-quality materials and a state-of-the-art production process, the new WP XPlor 48 fork – with approx. 300mm of travel – has outstanding response and damping characteristics. A comfortable preload adjuster can be retrofitted and allows for a simple spring preload setting in three steps without tools (standard, +3mm, +6mm).

Rear suspension

The PDS is kind of a KTM trademark where the shock absorber is directly connected to the upper side of the swingarm. This setup boasts the best possible mounting geometry and provides amazingly progressive damping. The shock absorber is mounted close to the centerline, which means nearly symmetrical loads for the swingarm and frame and more space for the exhaust system. A second piston works together with a closed cup (instead of a needle) towards the end of the stroke and is supported by a progressive shock spring for exceptional bottoming resistance. Various machined and anodized components and a distinctive WP color trim make this a valuable, high-end product compared to the less refined shock absorbers of the competition.

Triple clamp

Fitted with forged triple clamps with an offset of 22mm, ensuring a solid grip of the fork and precise handling. The handlebar is adjustable forwards and backwards over 4 positions, so the EXC TPI will fit you like your favorite gloves.

Fuel tank

Fuel tank

This is a lightweight polyethylene tank with a capacity of 9.25 liters. The EXC TPI models incorporate a new integrated fuel pump system and an additional fuel level sensor so you’ll always know when you’re running low on gas.

Airbox

Airbox

The air filter box design offers maximum protection of the air filter against soiling, while ensuring maximum airflow. The EXC TPI models get a new intake snorkel designed for the new throttle body while also hosting an air temperature sensor. The large Twin Air air filter is mounted on a stiff cage, which at the same time holds the system in place. This design is so simple, you could still pop a fresh one in with a face full of mud. Without tools. In seconds.
