KTM RC 390/390 Duke PARTS & Accessories

KTM RC 390 & 390 Duke Parts & Accessories at HardRacing

KTM's RC 390 and 390 Duke represent the sharp end of single-cylinder sport bike engineering — lightweight, agile, and packed with technology borrowed directly from KTM's MotoGP and WSBK programs. HardRacing stocks a growing selection of KTM RC 390 and 390 Duke performance parts, accessories, and upgrades to help you get the most out of your orange machine.

The most popular KTM 390 upgrades start with exhaust systems — the stock muffler is notably heavy and restrictive, and aftermarket options from brands like Akrapovic, Two Brothers, and SC Project transform both sound and performance. Braided brake lines, upgraded brake pads, and adjustable levers improve the already excellent braking feel. ECU tuning solutions, air filters, and quickshifter accessories round out the performance package for track riders.
