E-STARTER
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.

EXHAUST
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.

COOLING
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.

FRAME
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. The specific design guarantees a precisely defined stiffness in conjunction with an optimal geometry. As a result, the rider enjoys first-class feedback, responsive handling that works perfectly with the suspension to provide excellent agility at low and high-speed. The subframe is made from extremely lightweight and highly stable aluminum sections that provide great feeling for the rider.

SWINGARM
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.
