TOTAL TERRAIN DOMINATION: INTRODUCING THE 2023 KTM ENDURO RANGE
KTM has dominated Enduro competition for a number of decades, with the newest iteration of the 2023 KTM EXC and EXC-F models set to continue the trend. Boasting an updated design, orange-coated Chromoly steel frame, race-proven WP XPLOR suspension at each end, and real READY TO RACE credentials, the 2023 KTM Enduro range is the one to beat.
Offering the most extensive READY TO RACE competition Enduro lineup on the market, starting with the enduro underdog KTM 150 EXC 2-Stroke and topping out with the class-leading power KTM 500 EXC-F 4-Stroke, the 2023 KTM Enduro range caters to all riders and terrains.
New for 2023, an all-new graphic design and white, purple and orange color scheme come together into a seamlessly blended palette. This color scheme was specifically chosen by the designers to pay homage to the early ‘90s enduro models, setting the 2023 KTM Enduro range apart from anything else on the trails.
The looks are further emphasized with the use of a race-inspired orange-coated Chromoly steel frame. Not only does this echo the styling on full-factory race machines but provides the perfect backbone to set off the 2023 graphics pack.
In terms of engines, the 2-Stroke model range once again takes its place and is the leader in the paddock, making use of KTM’s patented Transfer Port Injection (TPI) technology. Not only has this ensured fewer emissions and fuel consumption but provides smooth and strong power delivery from the bottom right through to the top end of the rev-range.
The 4-Stroke model range provides the most concise offering of models, starting with the KTM 250 EXC-F and KTM 350 EXC-F and topping out with the powerhouses KTM 450 EXC-F and KTM 500 EXC-F. All models in the 4-Stroke range benefit from class-winning engines, engineered to deliver massive torque down low with class-leading power delivery at higher RPMs.
These are flanked by the ever-popular KTM EXC SIX DAYS range, which offers a special tribute to the upcoming 2022 FIM International Six Days Enduro in France, combining the very latest in innovation with an extensive list of race-derived parts as standard.
Every motorcycle in the range gets fully adjustable WP XPLOR suspension as standard, with the advantage of a Progressive Damping System (PDS) on the rear. The PDS layout – a staple across KTM EXC and EXC-F models, offers lower maintenance due to fewer moving parts, but provides more ground clearance, with less chance of hooking up when climbing logs or rocks.
As always, and thanks to KTM’s global network of dealers, the availability of support and parts needed to compete at the highest level are easily accessible, with the added availability of dedicated KTM PowerWear and KTM PowerParts designed to allow for the highest levels of performance, protection, and mobility for all offroad riders and racers.
The 2023 KTM Enduro range is derived from years at the top level of offroad racing and brings together a dynamic combination of race-bred performance, ergonomics, and technology ready to tackle any terrain.
2023 KTM 450 EXC-F Totalmotorcycle.com Features and Benefits
Engine & Exhaust
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.
Engine
Combining compact dimensions with immense power output, this 449.9 cc fuel-injected SOHC powerplant is the most powerful and refined on the market. Its class-leading power delivery is available throughout the entire rev range and with its low weight of only 29.2 kilograms, it’s also one of the lightest 450 cc mills out there.
Cylinder head
The KTM 450 EXC-F engine is fitted with a compact SOHC cylinder head for optimal mass centralization. The head configuration promises efficient power delivery and unrivaled performance. A single overhead camshaft also ensures optimal gas flow, with low-friction rocker arms and timing chain guides guarantee consistent performance throughout the rpm range.
Crankshaft
Located in an ideal position close to the center of gravity, The KTM 450 EXC-F crankshaft contributes to easier handling. It utilizes a short connecting rod, which makes for an overall compact and lightweight engine. The engine’s pressurized lubrication system provides the necessary oil feed for the big end bearing. This design has a direct benefit for the crankshaft with extended service intervals. So just pin it, all day long.
Crankcases and engine 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 450 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 95 mm bore cylinder is an extremely lightweight, box-in-box type piston made by König. In conjunction with the light but extremely durable piston pin, it is a major contributor to the engine’s high performance, low vibrations, and speed. The compression ratio of 12.75:1 delivers exceptional engine performance and reduces the risk of engine knocking. Additionally, the top of the piston is optimized for highly efficient fuel combustion.
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 450 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 450 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.
