2023 KTM 250 EXC-F Off-Road Bike Review Specs

The 2023 KTM 250 EXC-F Off-Road Bike, which may be the smallest 4-stroke engine available from KTM, is surprisingly robust. Motivated amateurs and ambitious professionals alike have long favored the KTM 250 EXC-F due to its small size, lightweight, and excellent handling. Because of its sophisticated fuel injection system, this engine also provides class-leading performance, low-down torque, and confidence-boosting power delivery.

2023 KTM 250 EXC-F Off-Road Bike – Features and Specs

Engine & Exhaust

In terms of performance and power delivery, the exhaust is a significant and formidable weapon. The header pipes on all 4-stroke EXC models are made of two pieces that are simple to detach and provide quick access to the shock. Because of its short and compact design, the aluminum silencer sleeve improves mass centralization by putting the weight closer to the center of gravity.

Engine

The fuel-injected DOHC engine of the 2023 KTM 250 EXC-F Off-Road Bike is the most potent and sophisticated 250 cc on the market, with compact proportions and class-leading power output better than 2019 KTM 250 EXC-F. At only 27.9 kg, this engine is the lightest and most competitive power plant available, and it offers efficient power delivery over the whole rpm range. Not only is it environmentally friendly, but it also makes the competitors envious of its Euro IV homologation.

Crankshaft

The crankshaft of the 2023 KTM 250 EXC-F Off-Road Bike is well positioned near the center of gravity, which facilitates handling. Because of the short connecting rod, the engine is lightweight, compact, and has a rapid power delivery. Directly on the crank pin is a simple large (bottom) end bearing including two force-fitted bearing shells. The engine’s pressurized lubrication system supplies the required oil supply for this bearing. Because of the simple bearing, this design directly benefits the crankshaft and its longer service intervals. Pin it and enjoy your day.

PANKL Racing Systems produced a sturdy 6-speed gearbox for the 2023 KTM 250 EXC-F Off-Road Bike. Because the gears are composed of a robust, forged raw material, the maximum dependability and longevity are guaranteed. The gear ratios are precisely suited to the engine’s power characteristics; thus, adjusting them was unnecessary. 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 easy to reach and route the cables efficiently. The handlebar map-select button activates the ECU’s selectable engine maps, tailored to the engine arrangement, exhaust, and air box, controlling the unique traction control. It offers distinct maps for each gear based on data from the gear sensor to guarantee optimal power when you change through the gears.

Cylinder and piston

With a meager weight, a forged bridging box-type piston manufactured by CP is housed within the small 78 mm bore cylinder. The piston’s distinctive crown form has been modified to fit the geometry of the combustion chamber. It is very light, yet it has an extra robust construction for increased longevity. Because of its lightweight design, the engine has low oscillating masses and very dynamic characteristics. The engine performs quite well and has less chance of knocking, thanks to the 13.8:1 compression ratio.

Cooling

The ideal engine temperature is essential for guaranteeing constant horsepower throughout the journey. For optimal ergonomics, the 2023 KTM 250 EXC-F Off-Road Bike radiators are positioned near the center of gravity and precisely complement the shroud design. By combining CFD technology (Computational Fluid Dynamics) and sophisticated coolant circuit routing, the unique system maintains optimal engine temperature for the most outstanding performance.

Above all, the massive center tube of the delta distributor, which is incorporated into the frame triangle, contributes to the very efficient coolant flow from the cylinder head to the radiators. In the case of an accident, the unique shields on the radiators serve as a brace to distribute energy around the radiators and shield them from flying rocks and debris.

Frame

High-tech, lightweight Chromalloy steel frames with race-derived shape, ideal stiffness, and unmatched rider input are standard on all KTM EXC models. Thanks to the eye-catching orange finish, this translates into a fun handling character with excellent stability at speed and FACTORY RACING flair. The subframe is comprised of extra-light and ultra-stable aluminum profiles, weighing less than 900 grams, offering rear fender stability and durability in the case of a loop out.

Swing arm

The 2023 KTM 250 EXC-F Off-Road Bike has an aluminum swingarm produced in one piece via a gravity die-casting technique. It makes the ideal flex behavior and remarkable strength at the lowest feasible weight.

Wheels

For all EXC models, KTM employs premium GIANT rims and lightweight, CNC-machined hubs. These provide optimal stability and minimal weight, and the unique shape of aluminum spoke nipples lessens the need for constant spoke tightening.

Tires

The race-spec, puncture-resistant MAXXIS MaxxEnduro is designed for comfortable all-day riding on any terrain, thanks to its exceptional grip and performance.

Suspension

Top-tier WP suspension systems are standard on all KTM EXC-F models starting in 2023 to give riders of all skill levels unparalleled performance and consistency on all terrain types.

Front Suspension

This 48 mm diameter WP XPLOR upside-down forks, which set the standard for endure-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 the most excellent rear wheel traction.

Brakes

These high-tech Brembo puppies are coupled with lightweight Wave brake discs. The brakes could be a little more powerful or responsive on an off-road motorbike.

Fuel tank

Lightweight polyethylene tanks are standard on all EXC models, which enhances ergonomics. The bayonet filler cap with a ¼‐turn allows for rapid and straightforward sealing. Because it is made of see-through plastic, you can always see how much gasoline is left at a look. It has a gasoline level sensor and an integrated fuel pump system installed. For further protection against damage, the gasoline line has a 90° coupling to the tank.

Ergonomics & Comfort Place

Feel free to have a seat. The 2023 KTM 250 EXC-F Off-Road Bike has a grippe black vinyl seat that is ideally contoured to enable the rider’s maximum range of motion while being sufficiently comfortable for extended periods in the saddle.

Handlebar

High-strength aluminum tapered handlebars that are adjustable and manufactured by NEKEN comes standard on 2023 KTM 250 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.

Bodywork & Graphics Decals

The 2023 KTM 250 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.

Software & Electronics Battery & wiring harness
