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 320g. 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.
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.
The KTM 450 SMR features a SUTER antihopping clutch which prevents rear wheel instability and hopping when braking hard into the apex of a turn, for maximum control and perfect Supermoto-style drifting. The Brembo hydraulic system guarantees perfect clutch modulation.
The standard electric starter on the KTM 450 SMR 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.
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.
Maintaining the optimal engine temperature is crucial to ensuring consistent horsepower throughout the ride. The KTM 450 SMR features radiators which are positioned for a lower the center of gravity. Their design matches the shrouds perfectly and offers a great slim feel to the ergonomics. By using CFD technology (computational fluid dynamics) together with a clever coolant circuit routing, the innovative system ensures the optimum engine temperature for the highest performance, no matter what the conditions. The radiators also feature special protectors that don't only serve as protection from debris but also as a brace that disperses energy around the radiators in the event of an impact.
The KTM 450 SMR's one-piece swingarm, is manufactured using a gravity die-cast production process, for exceptional strength at the lowest possible weight. It offers a wide range of adjustment for the rear wheel, allowing for a shorter wheelbase on tighter twisty tracks, or a longer wheelbase for greater stability on longer track. The swingarm's chain measurement markings are visible from above, making adjustment simpler and more accurate.
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 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.<br />A 22 mm diameter front axle provides a precise fork response under heavy braking into a corner.
A Supermoto-specific set-up of the WP XACT rear shock absorber provides advanced damping characteristics for unsurpassed traction and energy absorption, while keeping a compact and lightweight design. The component is fully adjustable and matched to a linkage system with a specific geometry to deliver the greatest possible traction and absorption.
