Sirris R46 Shock Spring | By Sirris Suspension | For R46 Rear Shocks on E-Moto Platforms

Dial In Your Suspension With the Correct Spring Rate

At REV Rides we always remind riders that proper suspension setup starts with the correct spring rate. The Sirris R46 Shock Spring is designed specifically for Sirris R46 rear shocks, allowing riders to fine tune their suspension for rider weight, riding style, and bike setup. Choosing the right spring rate ensures the shock performs the way it was designed, delivering better traction, improved balance, and consistent suspension performance.

Many riders upgrade components like batteries, controllers, or other parts that add weight to the bike. When that happens, the suspension may need a heavier spring rate to maintain proper sag and ride characteristics. Sirris offers a range of spring options so riders can match their suspension to their build and riding style.

Why the Correct Shock Spring Matters

• Optimizes suspension sag for improved traction and balance
• Maintains proper damping performance from your R46 shock
• Supports heavier upgrades such as larger batteries or controllers
• Improves stability during aggressive riding
• Allows suspension tuning for rider weight and terrain

If you upgrade your bike with a larger battery or heavier components, we typically recommend stepping up one spring rate to compensate for the additional weight. This helps maintain correct sag and ensures the suspension continues to perform properly.
