Engineered by Sirris, tuned by Zero Motorcycles, and built to unlock balanced trail performance from the rear of the bike. The Sirris R46 XE shock is a direct-fit suspension upgrade developed around the XE platform’s geometry, weight balance, and real-world trail demands. With wide-range trail valving, adjustable low-speed compression, rebound, and spring preload, it gives riders the support, comfort, and control needed to ride faster, longer, and with more confidence. Tuned for trail riding as part of a complete vehicle system—not a generic race conversion—the XE shock brings Sirris hardware and Zero-developed ride character together in one refined rear suspension package.
