The final round of the EMR race series at Glen Helen Raceway delivered a high-impact finale, and Sirris Suspension showed up in force — with factory support, a dedicated booth, and a clean sweep of the podiums across multiple classes.
From prototype suspension debuts to championship-level results, Sirris continues to define the standard in high-performance electric motocross suspension.
Race Highlights
Stark Open Class — Trevor Stewart delivered a commanding performance aboard the Bonnell 902, securing the overall win and marking the first official race victory for Bonnell. It was a defining moment, powered by Sirris Suspension.
Midsize Open Class — Total domination with a full podium sweep backed by Sirris. Trevor Stewart took the top spot on the new Mayhem Racing suspension kit for the E-Ride Pro. Max Beaupre followed in second on the Bonnell 805, and Riley Drickersen secured third on his Surron Ultra Bee — an all-Sirris-powered podium.
Prototype R38 Rear Shock Debut
Sirris debuted the highly anticipated prototype R38 rear shock on @Maddie.951’s fully custom E-Ride Pro, built by Surmomster. The build also features the Sirris CMX fork, custom decals and graphics, and a powder-coated frame — one of the most visually stunning bikes at the event.
Mayhem Racing Suspension Kit
The new Sirris front and rear suspension kit with a custom Mayhem Racing tune for the E-Ride Pro SR proved itself on race day with Trevor Stewart’s 1st place finish. Developed with Tim Ritson, the kit is available now and covered in depth on Sirris’s Mayhem page.
Bonnell & Tork
Bonnell made its first official race appearance in dominant fashion — the Bonnell 902 took the Stark Open top spot, and the Bonnell 805 grabbed second in Midsize Open. Both run factory-equipped Sirris Suspension.
Tork Bikes showed up with two machines fitted with the prototype R38 rear shock, giving fans an exclusive look at what’s coming next. Both upcoming Tork models will be factory-equipped with Sirris from the showroom floor.
The Bottom Line
EMR Race #3 was a statement weekend for Sirris. The R38 prototype shock, the Mayhem Racing kit debut, and the full-podium sweeps across classes show that Sirris isn’t just making suspension — they’re shaping the future of electric motocross performance.
