Cernusco Lombardone, Italy (July 31, 2026) – Regina Catene Calibrate S.p.A., a global leader in the production of high-performance motorcycle drive systems, is proud to announce its prestigious technical partnership with KTM for the new KTM 1390 Super Duke RR Track, one of the most extreme hypernaked motorcycles ever developed by the Austrian manufacturer.
For this model, engineered with a clear racing focus, KTM selected Regina’s expertise and engineering know-how to equip the motorcycle with a purpose-designed chain developed to deliver the highest levels of reliability, efficiency, and durability under the most demanding operating conditions.
The KTM 1390 Super Duke RR Track represents the ultimate expression of the Austrian brand’s ‘Ready to Race’ philosophy, combining extraordinary power, a highly refined chassis, and components derived directly from the world of motorsport. In this context, the final drive system plays a critical role in transferring the engine’s full power to the ground with maximum precision and confidence. It must withstand exceptional mechanical loads while delivering uncompromising reliability, even under the most demanding track conditions.
The intended use of the KTM 1390 Super Duke RR Track is clearly reflected in its name: it is a highly sophisticated machine engineered exclusively for uncompromising track riding. For this project, the manufacturer from Mattighofen selected a dedicated version of the Regina 525ZSAW chain. Produced in a limited series exclusively for this model, it is not intended for sale through the aftermarket, underscoring its exclusive, OEM-specific nature.
Chain Developed for Ultimate Performance
The KTM 1390 Super Duke RR Track has been engineered to deliver the highest level of performance on a naked bike platform already at the top of its class. Its exceptional power output, explosive acceleration, extreme torque, and intensive track use demand a final drive system capable of providing uncompromising precision, reliability and long-lasting durability.
To meet these requirements, Regina has developed an exclusive version of the 525ZSAW, a racing chain derived directly from the company’s experience in world-class motorcycle competition. It has been specifically engineered to deliver outstanding mechanical strength, dimensional stability, and consistent reliability, even under the most demanding operating conditions, where loads on the final drive system reach exceptionally high levels.
The chain’s construction is optimized to ensure the following:
- High-tensile strength and outstanding wear resistance
- Stability under extreme acceleration and deceleration
- Precise power transmission
- Consistent reliability, even under the most demanding track conditions
Thanks to these features, the 525ZSAW is specifically engineered for ultra-high-performance motorcycles, prototypes, and special OEM models, where the final drive system must deliver the highest levels of safety and efficiency without compromise.
Every detail has been optimized to match the characteristics of the Super Duke RR Track, while maintaining an exceptional balance of lightweight design, smooth operation and mechanical efficiency. An exclusive product developed for a special project, it reinforces the highly specialized nature of the motorcycle and further enhances the outstanding performance and engineering excellence of the new KTM.
