Turn your E-Ride Pro SR into an outright weapon
Sirris Suspension and Mayhem Racing teamed up to deliver a purpose-built, race-only suspension system that completely redefines what’s possible on a compact e-moto. This isn’t an upgrade—it’s a transformation.
Designed exclusively for elite riders chasing wins, this custom Sirris Pro MX race-only tune unlocks true big-bike performance on the E-Ride Pro SR. You get access to the race-proven R46 rear shock platform paired with a 230mm travel fork (826mm extended length)—a combination that simply doesn’t exist anywhere else for this class of bike.
The result?
Two additional inches of ground clearance. Massive suspension authority. Total control at speed. From flat-out straights to deep whoops and send-it landings, this kit delivers the confidence and composure of a full-size race bike in a compact, ultra-aggressive e-moto package.
Suspension Tune
This setup was born on the racecourse, originally developed for Arenacross, then refined through hands-on testing and collaboration with the Mayhem Racing team.
Both the Sirris F43 fork and R46 shock feature a custom, Pro MX race-only tune built for riders who push hard and land harder.
Tune characteristics:
• Stiff, aggressive MX race valving
• Hybrid MX/SX philosophy
Maximum support for:
• Huge jumps
• High-speed whoops
• Hard charging corner entry and exit
This tune is all about control, precision, and stability when it matters most. It rewards commitment, holds its line under abuse, and stays composed when lesser setups fold.
If you’re racing to win—and you want the most advanced suspension ever put on an E-Ride Pro SR—this is it.
No shortcuts. No compromises. Just pure race performance.
Built Together. Installed with Intention.
This E-Ride Pro SR race platform exists because two specialists did what they do best.
Sirris Suspension engineered and manufactured the fork and shock.
Tim at Mayhem Racing defined how it fits the bike—and how it should be installed.
Required Shock Fitment Modifications
This is a true race setup, and proper installation is part of the deal.
To fit the E-Ride Pro SR:
• A Mayhem Racing custom upper gooseneck adapter is required to fit the rear shock onto the frame
• Installation involves drilling the frame
• All parts and hardware are included with the kit
• Optional step: If you want to use the larger bolt for bottom linkage, the stock linkage must be drilled to accept the new supplied larger bolt
• No modifications to the frame are needed for the front fork.
