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.

Optimizes suspension sag

Setup Tip

If you upgrade your bike with a
