450 SMR 2022
THOROUGHBRED RACE MACHINE
The KTM 450 SMR is a pure expression of the READY TO RACE motto coming straight from the dealer floor with a premium setting of performance that will cause throttle hands to tremble. For 2022, it is heavily based on the championship winning KTM 450 SX-F that is the industry benchmark. The KTM 450 SMR features an extremely compact, single overhead camshaft engine that produces its power in the most effective way possible. The bike is fitted with premium components all-over, making it the most complete and most competitive model in the Supermoto racing segment. In brief, the KTM 450 SMR is the ultimate Supermoto racer!
When maximum power is needed, there is no alternative to the stunning engine of the KTM 450 SMR. It's performance has been demonstrated in the world's toughest competitions such as the AMA 450 Supercross World Championship and the MXGP World Championship. The SOHC power plant is the perfect example of the advanced engineering techniques offering a peak power at an overall weight of just 27.3 kg. Mass-centralisation is key in the engine design, enabling chassis engineers to position the engine closer to the centre of gravity for great handling and maneuverability.
The KTM 450 SMR is equipped with high-strength aluminum tapered handlebar, made by NEKEN. The handlebar is fixed in rubber damped mountings, which allow for two different positions. The handlebars come standard with an ODI vulcanized grip on the right side and a comfortable ODI lock-on grip, which does not require any wire or glue, on the left.
High-tech Brembo S.p.A brakes have always been standard equipment on all KTM motocross and enduro bikes. Stopping power on Supermoto is crucial, that is why the KTM 450 SMR has been equipped with Brembo's 4-piston radially mounted caliper and supported with Brembo's radial master cylinder working together with a 310 mm front disc. A single piston caliper and a 220mm disc is fitted to the rear, this combined with perfectly placed controls allow for optimal feel and control when sliding the bike into a corner.
The KTM 450 SMR model is fitted with the super-lightweight WP XACT fork with AER technology and feature updated settings for Supermoto use. It is a 48 mm USD air-sprung fork with a capsulated air spring on the left side and pressurized oil chamber for progressive and consistent damping on the right. In combination with the mid-valve damping system, the fork provides exceptional feedback and rider comfort. The setting is specifically made for Supermoto racing and can be easily adjusted via the single air pressure valve for the air spring, as well as through easy access click adjusters for compression and rebound damping. The air pump needed to adjust the fork's air pressure is provided as standard.A 22 mm diameter front axle provides a precise fork response under heavy braking into a corner.
The KTM 450 SMR is fitted with ultra light weight and strong black ALPINA spoked wheels, 16.5'' front rim and 17'' rear rim respectively. They are complemented by tubeless Bridgestone 125/600 R16,5 and 165/630 R17 slick tires for maximum grip, traction and agility.
The KTM 450 SMR benefits from a lightweight high-tech frame made of chromium molybdenum steel sections that include hydro-formed elements welded together by state-of-the-art robots. For 2022, the KTM 450 SMR introduces a frame finishing coated in racing orange to further reinforce the proximity to the championship winning machines of the Red Bull KTM Factory Racing stars. The frame design guarantees a precisely defined stiffness in conjunction with an optimal geometry with the rider enjoying first-class feedback and ultra-responsive handling. The subframe is made from extremely lightweight and highly stable aluminum sections that provide optimum riding feeling.
When it comes to power delivery and performance, the exhaust on the KTM 450 SMR plays a key role and packs a punch that is hard to beat. It features a model specific header pipe with an advanced resonator called FDH (Flow Design Header), which is a small chamber around the pipe. The design allows the exhaust to be disassembled without removing the shock absorber and also provides better access to the shock. The aluminum sleeve, end cap and internal design of the silencer allows for slimmer ergonomics, making the bike feel narrower, without compromise to regulatory noise limits.
Cylinder and piston
The lightweight aluminium cylinder is an engineering masterpiece. Featuring a 95 mm bore and a CP bridge-box-type piston which weighs only 320 g. It's design contributes to the engine's low vibrations and overall engine speed strength. Due to the low oscillating masses, the engine is not only powerful, but also displays extremely lively characteristics.
Engine Management System
The state-of-the-art KEIHIN Engine Management System, with electronic fuel injection, features a 44 mm throttle body. The injector position guarantees optimal atomization of the fuel and air on the way to the combustion chamber, resulting in instant response and maximum performance when opening the throttle. There are also separate systems for cold starting and idle adjustment. The ECU features maps which have been developed to precisely match the exhaust and cylinder head, with options for regulating traction and launch control. It also provides different maps for each gear, according to the information received from the gear sensor, ensuring maximum power as you shift through the gears.
The lightweight 5-speed gearbox features well-spaced gear ratios for Supermoto and is produced by Pankl Racing Systems ensuring the highest level of durability and reliability.An advanced gear sensor selects a specific engine map tailored for each gear.
