A new, ultra-lightweight frame design saves 3.3 lbs (1.5 kg) over the previous generation, making use of a trellis frame and bolt-on subframe, which also gives the KTM RC 390 improved high-speed stability and increased rider feel. The result? Faster lap times.
The KTM RC 390 makes use of a completely new suspension setup, giving it real race-bike credibility with unmatched specifications in the sub-400 cc Superpsports segment.
Boasting a 43 mm WP APEX open cartridge, adjustable upside down front fork with 30 clicks of compression and rebound damping adjustment, the KTM RC 390 not only shares proper sportsbike technology with bigger bikes, but it also handles like them too. New axle clamps and a hollow axle save weight up front too.
Rear Shock Absorber
Tuning your KTM RC 390 to be the perfect track day tool is easy, thanks to a new rebound and preload adjustable split-piston WP APEX shock absorber taking care of things in the rear.
Reigning in a charging KTM RC 390 comes courtesy of radially mounted 4-piston-fixed BYBRE caliper combined with a 320 mm brake disc upfront and a one-piston fixed caliper with 230 mm disc brake setup on the rear wheel. Not only do these provide the best possible deceleration, they save 960 grams of weight and can be fully exploited thanks to state-of-the-art ABS technology. An adjustable front brake lever completes the package.
An all-new bionic wheel design features fewer spokes and open hubs, which not only greatly improves handling characteristics, but most importantly, saves a massive 7.5 lbs (3.4 kg) of rotating unsprung mass. This means quicker turn-in on the track and improved durability on the street, making the KTM RC 390 an all-out apex-clipping master.
