Sirris E-Moto Suspension

Sirris Inc is a US suspension company founded in 2023, rider owned, with engineering in New Hampshire and its own manufacturing facility in Taiwan. It makes forks and shocks for e-motos only. The current range is the F43 fork and the R38 and R46 shocks, built on motocross architecture rather than adapted mountain bike parts.

Sur-Ron Ultra Bee, Sur-Ron Light Bee LBX, Talaria MX5, E-Ride Pro SR, E-Ride Pro SS 2.0, E-Ride Pro SS 3.0 and Ventus One+. The F43 is the front fork and fits all of them. The rear shocks are bike specific: the R46 fits the Ultra Bee, the R38 fits the E-Ride Pro SR and SS 3.0. You can run a fork on its own, a shock on its own, or both. If your bike is not on the list, ask, because Sirris keeps adding fitments.

F43 forks start at $3,200. A drop crown adds $150. The Ultra Bee fork in SX tune is $3,650. R38 and R46 shocks are $1,300. All prices in AUD from Melbourne Powered.

Every Sirris fork and shock is ordered against a rider weight band, and the bands differ between products. The Ultra Bee R46 shock has six, from 59 to 73 kg up to 127 to 159 kg. The E-Ride Pro R38 has two, 63 to 81 kg and 81 to 100 kg. Weigh yourself in the gear you actually ride in. If you land on the line between two bands, call the workshop on (03) 9088 2153 rather than guessing.

The three tunes get progressively firmer. Trail is the softest, aimed at trail and technical riding where you want the suspension working over small stuff. MX is set up for motocross tracks, jumps and repeated hits. SX is the firmest, built for supercross-sized jumps and hard landings. Trail and MX suit most riders. If you are not racing, you probably do not want SX.

Yes. Our workshop at 132 Union Rd, Ascot Vale can fit the fork or shock and set sag and clickers for your weight and riding. Book it in when you order and the bike goes out ready to ride rather than ready to fiddle with. Call (03) 9088 2153 or email workshop@melbournepowered.com.au.

Some tunes and weight bands are on the shelf, most are ordered in. Because every unit is built to a weight band and a tune, we would rather order yours correctly than sell you the one that happens to be in the box. Text or call 0483 930 491 with your bike, your weight and the tune you want and we will give you a real ETA before you pay anything.
