Engineered for track‑ready precision, the Supersport‑K D30 jacket showcases RST’s most advanced leather construction to date. A full‑grain kangaroo leather chassis forms the backbone of the piece, delivering a lightweight yet ultra‑durable shell that thrives under the high‑G forces of supersport racing and the aggressive demands of street riding. Integrated 4‑way stretch zones are strategically placed to preserve a razor‑sharp fit while allowing unrestricted movement through corner entry, braking, and rapid body shifts.
Ergonomic freedom meets climate control through a next‑generation 3D mesh lining that hugs the rider’s torso while actively managing heat and moisture. Panel‑in‑panel perforations paired with airflow‑optimized internal channels create a continuous ventilation pathway, keeping the rider cool on blistering track days and comfortable during extended street sessions. The refined fit works in concert with the stretch zones, delivering a cockpit‑like feel without sacrificing protection.
Certified protection without compromise is built into every seam, with CE AAA certification confirming the jacket meets the highest European safety standards. D3O Level 2 inserts safeguard the shoulders and elbows, while optional back and chest protector pockets let riders tailor coverage to their riding style. Updated carbon shoulder cups add an extra layer of impact resilience and a bold visual cue, ensuring the Supersport‑K D30 performs reliably in real‑world racing environments and high‑speed street runs alike.
