Can I change tyres of my KTM RC 390 with front 120/70-17 and rear 160/60-17 or 180?
Replacing bike tyres recommended by the company with different tyres is not that easy, a lot of things need to be taken into account while changing the tire as tires expand at speed, and temperature and centrifugal force cause a spinning tire to be measurably larger than one at rest and the tires that are too wide can hit swingarms, chains, or driveshafts and tires that are too large in circumference change gearing ratios and speedometer readouts, and can contact fenders or swingarms.
The dimension of the KTM RC 390 tyres are:
Front Tyre 110/70 × 17
Rear Tyre 150/60 × 17
So we don’t advise you to experiment with fitting a different dimension tyre as the tyre designed by KTM is the best for your RC 390
