If your looking for a high power bike at the lowest cost here is the beast KTM RC 390 is very impressive both performance and looks.
Guys frankly if you want a racing bike dont think about mileage as it is going to be low the average of this beast is about 15-20 in bumber to bumper traffic. Highway it is upto 30 and city 20-25.
The bike has no negative things but it does lack comfort alot but it has more comfort than previous version and also many changes have made it butter smooth performance.
It has ABS so braking is very nice and also the brake design has changed and the grip is awesome the brakes are awesome.
I love to ride my Ktm RC 390 alot it is the best bike its performance is just dam good. Also it is affordable and has a low maintenance too.
