Duke 390 is a well-known bike for being agile and fast. Its 390cc engine updated to Euro 5 standards does not stand out for top performance, but it is highly appreciated for delivering good handling and plenty of fun. Rapid Bike goal is to match the expectations of genuine two-wheels enthusiasts looking for enhancing their riding experience thanks to winning fueling solutions such as Evo and Racing kits!

KTM mono cylinder engine gains a different flavor in terms of torque delivery thanks to Rapid Bike Evo management of injection values. Rapid Bike Racing, on the other hand, allows for Duke 390 to reach top performance considering the additional contribution of ignition re-mapping.

Dyno tests performed with the bike in stock configuration highlight remarkable results at different TPS openings, with an increase of 4 hp starting at 7000 rpm and all the way up to 9000 – this is quite a valuable power gain considering 390 Duke’s reduced weight-to-power ratio!
