KTM celebrates its prowess in the world of offroad racing with the 450 EXC-F SIX DAYS. Built to perform under the toughest race conditions like those found at the Chilean ISDE, and boasting READY TO RACE componentry, it is well-equipped to take on anything thrown at it.

Engine & Exhaust

The hugely successful KTM 450 EXC-F power plant has kept its key ingredients the same for 2019 – compact dimensions, relentless performance throughout the rev range and low weight. Fitted with a single overhead-camshaft cylinder head and the latest electronic fuel injection, it churns out horsepower in line with what you’d expect from a pure-bred factory race weapon.

Chassis

Just like the rest of its SIX DAYS brethren, the 450 EXC-F SIX DAYS shares a race-winning chassis setup. WP suspension keeps the wheels planted, while weight-saving efforts and performance-orientated materials ensure riders and racers are well-looked after on the trail or on track.

Ergonomics & Comfort

Enduro racing is all about tough, technical terrain and fast, wide-open straights. It goes without saying that riders need to be able to move about the bike freely. With that in mind, KTM has ensured that the same READY TO RACE ergonomics of 2018 has been retained for 2019.

Bodywork & Graphics

Flying the Chilean colors for 2019, the plastics on the 450 EXC-F SIX DAYS share the same I-beam structure on its front and rear fenders as the rest of the multi-race winning enduro range. This guarantees maximum stability and low weight thanks to well thought-out construction and mounting points.

Software & Electronics

A state-of-the-art Keihin engine management system with electronic fuel injection features a unique injector position to give instant throttle response a whole new meaning. While on-the-fly engine mapping settings keep the power delivery perfectly mated to every condition.
