The intended suit of the bike is not as sharper, yet manages to look as aggressive and beastly as before. The sharp edgy front consists of two DRLs and independent projection headlamps. Comfier sitting, kinder ergonomics, a host of electronic and technical nannies and a large fuel tank for travelling longer make it as savage but no more lightweight or powerful than before. The rear-view mirror is wider and ensures better visibility. The new edition uses a combination of high-gloss white and black chrome paint with orange wheels and grid frames. The hint of orange on certain panels of the body makes the bike cooler and sportier. The abdominal exhaust of the bike makes way for the lateral exhaust which is BS6 compliant. The comfort and approachability of the bike is immediately apparent. The clip-on handlebars of the bike can be lowered by almost 14mm for adjusting the aggressive seating posture.

The super sport machine carries the same old 337 ss liquid cooling, single cylinder engine. But there are definitely some improvements and modifications such as the Bosch fuel pumps, EVAP and the CAN-BUS system inspired from the KTM Moto 3 WSBK models. This arrangement gives a peak torque of 36 Nm and an unmatched power of 43 PS. It can pick up a maximum speed of 200 kmpl. The engine feels grownup- pretty linear and tractable for the matter, having no glaring spikes or flat spots in its powerband. Throttle transition seems smoother and vibrations more in check. The acceleration is pretty nice but beyond 120 kmph it trails off noticeably and resembles the older BS4 bikes in this aspect.
 

The theme is apparent once it sets off. The outgoing KTM RC 390 is known for being super sharp but demands an experienced and precise hand for it to give the most. The new version retains this concerning quality, it is easier to rear it now than before. The new machine feels natural and predictable once the limit is hit, and overall, the KTM RC 390 continues to be sporty and agile which has become more friendly and neutral than before. However, it lives up to its old reputation for being a heavy machine with super-sharp handling. The new brakes and wheels are now lighter and its facelifted weight is cut off painstakingly in some areas like the chain guard and the frame. One cannot feel the few kilos added from the saddle and the bike actually feels pretty light and planted on its feet.

Overall, the new KTM RC 390 is pretty sturdy and well-built and aerodynamically it is more efficient now. The slip clutch shows great improvements in the new model; however, the switchgear seems a little clicky and does not feel good to operate. Downshifting in this bike is pretty fast and smooth, making clutch handling easier. This especially helps in congested city traffic. The performance of the bike at low and high speed seems to improve. It will not stutter when slowly pulled from 50 kmpl to 60 kmpl. However, beyond 90 kmpl, vibrations can be felt at the peg but the bike will still have ample power to keep running. Overall, the bike is smooth and fast and feels comfortable on the track.
