The KTC RC World Cup is an event watched by millions of fans, as it involves high octane action, thrilling spars and breathtaking models. Moreover, it serves as an exhibition for new parts, materials and components, such as new engines and moto air filters. In a former KTM RC Cup, for example, drivers were to use the race prepared RC 390, sold specifically for thecompetition and primed to the brim with all the necessary power parts. To uphold the competitive spirit and vibe, all bikes’ engines were sealed and could only be serviced by HMC Racing, KTM’s trackside partner. The RC390 boasts an incredibly light, 36kg, 44hp, 375cc fuel-injected engine in a Moto 3-styled package.
