This is the first major update for the sharp, slim and tempting KTM RC390. The obvious change on the new bike is the new colour scheme; it's still black and white but it now gets an extra splattering of orange. The new-for-2017 RC390 also gets a new belly pan courtesy an all-new exhaust system. The underbelly exhaust gives way to an aluminium end can, which may not be to everyone's taste, but personally, I think it looks fine. It makes the 390 sound better too, especially at full clip. The new RC390 also gets adjustable levers for both clutch and brake.
Other changes include a softer seat; a contact-less starter button that just requires one press to get the bike fired up instead of keeping the button pressed till the bike actually fires up; wider rear view mirrors, which certainly work better than before; and a plastic flap behind the rear monoshock to protect it against muck.
There are some significant technical changes as well. For better upkeep of the wiring system, the 390 now uses a CANBUS, the throttle is ride-by-wire, the front disc is larger (320mm instead of 300mm) with revised braking ancillaries like the master cylinder and pistons, and the new RC390 gets slightly inferior Metzelers both front and back. The latter are now H rated instead of W meaning they are cheaper and longer lasting but these are also only rated to 210kmph and not 240kmph as the W. The tyre compound is different too.
