FOR THE FASTEST SPEEDS

SPECIFICALLY MADE FOR MODIFIED BIKES

SIRRIS R46 SHOCKS

R46 FOR SURRON ULTRA BEE IS HERE. REVOLUTIONIZE YOUR BIKE'S POTENTIAL WITH HARMONIZED SUSPENSION FRONT AND BACK.

LSC and 2SC

LSC is low speed compression which offers superior pressure balance and frequency response providing the ultimate overall responsiveness and performance for riders.

2SC is two speeds (high and low) of independent compression adjustability.

Optional 2SC will be available soon and will offer a wider adjustment range than the LSC. LSC and 2SC fit in the same cavity and are cross compatible (with a rebuild). Both will be offered as service parts.

TUNES TO RULE THEM ALL

Sirris offers a wide variety of tuning options to fit your riding needs. Choose from Trail, MX and EBMX Tunes.

The internal tuning is accomplished by mixing the perfect match of spring weight, compression settings, rebound settings, preload settings and oil weight. All are internally adjustable and serviceable by a trained technician or service center.
