Cylinder head

The 2023 KTM 450 EXC-F Off-Road Bike engine is equipped with a small SOHC cylinder head for maximum mass centralization. The head configuration promises unmatched performance and adequate power delivery. A single overhead camshaft further ensures ideal gas flow, and timing chain guides and low-friction rocker arms guarantee constant performance throughout the rpm range.

Transmission

The 2023 KTM 450 EXC-F Off-Road Bike has a sturdy 6-speed gearbox from PANKL Racing Systems. Because the gears are composed of a robust, forged raw material, the maximum dependability and longevity are guaranteed. Every four-stroke engine has a gear sensor installed, which allows the engine to have a distinct characteristic for every gear.

Engine management system

The 42 mm throttle body of the state-of-the-art Keihin Engine Management System, which includes electronic fuel injection, has independent systems for idle control and cold starting. The throttle cable mount makes it extremely simple to access and route cables for consistently precise throttle response, like in the 2023 KTM 450 EXC-F Six Days.

Cylinder and piston

König’s box-in-box piston, which is very light, is housed within the compact 95 mm bore cylinder. It plays a vital role in the engine’s excellent performance, low vibration, and speed, especially when combined with the lightweight yet very robust piston pin. The 12.75:1 compression ratio minimizes the possibility of engine knocking while delivering outstanding engine performance. Furthermore, the piston’s top is better designed for effective fuel combustion than the 2019 KTM 450 EXC-F.

Balancer shaft

In addition to operating the water pump, the multipurpose side-mounted counterbalance shaft expertly balances all oscillating forces. Even at the fastest engine speeds, it efficiently reduces engine vibrations to provide the smoothest ride possible, better than older models, i.e., the 2018 KTM 450 EXC-F.

Clutch

The 2023 KTM 450 EXC-F Off-Road Bike has a robust, KTM-designed DDS clutch (damped diaphragm steel), heat-resistant clutch plates, and a wear-free steel basket. Its diaphragm spring replaces the standard coil springs, making clutch action more straightforward. Furthermore, the whole operating temperature range is covered by the simple and accurate clutch modulation offered by the Brembo hydraulic system.

E-Starter

A strong Mitsuba starting motor and a dependable beginning drive power the 2023 KTM 450 EXC-F Off-Road Bike’s standard electric starter. It offers reliable and rapid starting, proven repeatedly, saving valuable time and energy when needed.

Cooling

Two radiators are positioned around the center of gravity, which helps to keep the engine cool when things go rough. These employ advanced coolant circuit routing and computational fluid dynamics (CFD) technologies to achieve the ideal engine temperature for maximum performance under all circumstances. Above all, radiator fans are standard on all 4-stroke versions, and the delta distributor, built into the frame triangle, has a vast center tube for very efficient coolant flow.

Engine

The most potent and sophisticated 449.9 cc fuel-injected SOHC powertrain available today combines small size and enormous power output. Its class-leading power output is accessible over the whole rev range, and at only 29.2 kg, it’s one of the lightest 450 cc mills on the market.

Swingarm

The swingarm of the 2023 KTM 450 EXC-F Off-Road Bike is made of one piece of aluminum and is produced by gravity die-casting. It creates an ideal flex behavior and remarkable strength at the lowest feasible weight, better than the 2017 KTM 450 EXC-F.

Wheels

For the new 2023 KTM 450 EXC-F Off-Road Bike, KTM employs premium GIANT rims and lightweight, CNC-machined hubs. They provide optimal stability and minimal weight, and the unique shape of aluminum spoke nipples lessens the need for constant spoke tightening.

Tires

The race-specified, puncture-resistant MAXXIS MaxxEnduro tires are designed to offer good grip and are effective on any surface, making them ideal for comfortable all-day riding.

Suspension

Top-tier WP suspension systems are standard on the 2023 KTM 450 EXC-F Off-Road Bike, giving riders of all skill levels unparalleled performance and consistency on all terrain types.

Front Suspension

The new 48 mm diameter WP XPLOR upside-down forks, which set the standard for enduro-focused suspension, provide unparalleled performance for riders of all skill levels. Adjustment is straightforward, with a rebound on the right fork and compression damping on the left.

Rear Suspension

Conical bushings between the pistons of the race-tested, fully adjustable WP XPLOR shock absorber minimize suspension fading and wear. Furthermore, the PDS rear suspension design is the preferred option for podium contenders and sets the standard for excellent rear wheel traction.

Brakes

You’ll be glad this machine’s lightweight, wavy discs and sophisticated Brembo brake calipers handle the stopping duties. These also account for years of professional racing, offering the optimal balance of steel quality and pad density for durability and a reliable feel.

Fuel tank

Lightweight polyethylene tanks with a bayonet-style filler cap for fast and straightforward operation are standard on the new 2023 KTM 450 EXC-F Off-Road Bike. The integrated fuel pump guarantees direct fuel supply to the injectors, and the 90° connection prevents damage. Because the tank is made of see-through plastic, motorcyclists can quickly and easily check the gasoline level while out and about.

Airbox

Specially designed intake snorkels provide ideal flow dynamics in the easy-access airbox of the 2023 KTM 450 EXC-F Off-Road Bike. It implies the motor is force-fed air, producing the perfect power and throttle responsiveness mix. A sizable Twin-Air air filter fixed to a stiff cage for constant optimal positioning keeps the air pure.

Frame

High-tech, lightweight Chromoly steel frames with race-derived shape, ideal stiffness, and unmatched rider input are standard on the new 2023 KTM 450 EXC-F Off-Road Bike. Thanks to the eye-catching orange finish, it translates into a fun handling character with excellent stability at speed and FACTORY RACING flair. Weighing less than 900 grams, the ultra-stable and extra-light aluminum profiles that make up the sub-frame provide the rear fender resilience and stability in the event of a loop out.

Footpegs

Even while pulling through deep ruts, self-cleaning footpegs prevent dirt from sticking in the pegs. It implies that you keep your attention on the route and your boots keep their hold.

Handlebar

High-strength aluminum tapered handlebars that are adjustable and manufactured by NEKEN are standard on an all-new 2023 KTM 450 EXC-F Off-Road Bike. There are four possible mounting places for them. Your only concern is holding on and letting loose with the standard ODI vulcanized grip on the right side and the cozy ODI lock-on grip on the left.

Decals

The 2023 KTM 450 EXC-F Off-Road Bike takes cues from the RED BULL KTM FACTORY RACING TEAM. It has an orange-coasted frame and a striking color scheme inspired by the 1990s. The tried-and-true in-mold graphics application provides increased friction and fade resistance, so even after the roughest trail rides, your horse will still look brand new.
