Husqvarna came under KTM ownership in 2013 and its 2015 FS 450supermoto was unveiled as an alternative take on the KTM 450 SMR. These two models werepractically twins with different costumes, but as it turns out this was just anintermediate step. KTM has retained only the 690 SMC R in its supermoto range, so racingduties in the 450 class have been handed over to Husqvarna with an extensivelyupgraded FS 450.
The new Husky supermoto features a new frame, engine and gearbox, practicallymaking for a new motorcycle.
The drivetrain is based on the motocross KTM 450 SX-F that's undergone a strenuous redesign resulting in a 1.8 kg (4 lb) lighter and more compactengine unit. It is mated to brand new five-speed gearbox, smaller and lighterthan its predecessor, which is equipped with the APΤC (Adler Power Torque Clutch) slipper clutch toeliminate rear end hopping when braking and downshifting into a corner entrance.
The single-cylinder engine is controlled by the latest evolution of Keihin’sEngine Management System, the same electronic unit used by KTM. In the case ofthe 2016 FS 450, a new launch control function regulates torque output during thefirst two seconds after a standing start, helping to maximize traction.
The motorcycle is built around a new chromium molybdenum tubular steel frame with a new aluminum swingarm. The plastic subframe introduced in the 2014 FS 450 is has now been replaced by a smaller and lighter carbon-compositepart.
The 2016 FS450 is endowed with the typical gear that KTM uses, such as the fullyadjustable WP suspension and Brembo brakes, plus a lightweight pair of black Alpinaspoke wheels to complete the package.
After all the weight-saving and power-enhancing development work that wentinto the new FS 450, the output of 63 hp (47 kW) marks the most powerful engineever used in a 450 cc Husqvarna supermoto. This much grunt in a motorcycle that weighsin at just 105 kg (231.5 lb) sounds like an explosive combination – exactly whatit takes to compete in the S1 World Supermoto Championship. For reference, the2014 FS 450 produced 60 hp (44.7 kW) for a mass of 110 kg (242.5 lb).
The 2016 FS 450 is expected to hit Husqvarna’s dealers by the end ofSeptember at an as yet undisclosed price.
