E-moto Suspension & Handling Upgrades

Sirris Suspension for E-moto

Sirris suspension replaces the stock front and rear end on a light E-moto with full-size MX parts: the F43 upside down fork and the R38 2SC piggyback shock. The F43 comes in a separate version for each bike, with that bike's spring rates, brake bracket and wheel spacers, so you pick the listing named for your model. This page also carries the EXT Ferro air fork, two Traxion forks for the Surron Ultra Bee, and the headset, clamp, linkage and cockpit parts that go with a suspension swap.

"Shock cover only" means the one part on this page for that bike is the FactoryZ Shock Cover. Every other model has a fork, shock, chassis or cockpit part here; check each product's fitment block for the exact version.

Does NOT cover: Surron LB2 (also called the Light Bee 2). It is a new frame, and none of the forks, shocks or chassis parts here fit it.

Which suspension do I need?

Start with your bike, then the end of it. For the front, each Sirris F43 220mm fork is a separate part per bike: the Eride Pro SS 2.0, SS 3.0 and SR forks run different springs, and the Arctic Leopard XE Pro R fork carries a 240mm rotor bracket where the XE Pro S and Enduro fork carries a 220mm one. The Surron Ultra Bee gets a longer F43 with 246mm of travel, in MX Tune or Trail Tune.

For the rear, the Sirris R38 2SC is listed for the Eride Pro SR, the Eride Pro SS 3.0 and the Arctic Leopard XE Pro. Each one needs an R38 linkage, sold separately; the stock linkage will not work. Running one fork across several bikes instead? The EXT Ferro is a single air fork listed for the Light Bee, Talaria MX3 and MX4, Eride Pro SS 2.0 and SS 3.0, Ventus One+ and Rawr Mantis X, each with a rotor spacer or brake adaptor.

Eride Pro Suspension

Sirris F43 forks, 220mm of travel and 43mm chromed stanchions, one per model: Sirris F43 CMX Fork for Eride Pro SR, which runs stiffer springs than the SS 2.0 version; Sirris F43 CMX Fork for Eride Pro SS 2.0, built to the SS 2.0 spring rates; and Sirris F43 CMX Fork for Eride Pro SS 3.0, with Medium 3.6/3.6 and Heavy 4.0/3.6 spring options.

Sirris R38 2SC Rear Shock for Eride Pro SR and Sirris R38 2SC Rear Shock for Eride Pro SS 3.0: the same 289 x 78mm piggyback body with a 16mm shaft. The SR shock springs at 90 or 100 N/mm, the SS 3.0 shock at 80 or 90 N/mm. Both bolt up through the Prickly R38 linkage, sold separately.

Surron Light Bee Suspension

Sirris F43 CMX Fork for Surron Light Bee X: 220mm of travel, with a 220mm rotor bracket and Light Bee X wheel spacers in the box. Plan on a 220mm front rotor and a 4-bolt direct mount stem; the stock 200mm rotor and the stock stem do not carry over.

Surron Light Bee Suspension Triangle Upgrade: a thicker triangle milled from 6061-T6 aluminum, for every Light Bee year. Surron Headset Bearing Kit: OEM replacement cups, races, tapered bearings and lock collar for the Light Bee steering head.

Surron Ultra Bee Suspension

Surron Ultra Bee Sirris F43 Fork, MX Tune and Surron Ultra Bee Sirris F43 Fork, Trail Tune: 246mm of travel, 856mm free length, forged 6061 drop outs and triple clamps. MX Tune is firm for track riding and big jumps; Trail Tune is the more versatile setup and the one with a spring past 320 pounds.

Traxion 260mm Travel Fork for Surron Ultra Bee and Traxion S TiAlN Fork for Surron Ultra Bee: 260mm of travel, 38mm inner and 50mm outer tubes, and 24-stage compression and rebound adjust, with a CNC crown and stem in the box. The Traxion S adds TiAlN coated stanchions.

For the stock fork and the rear end: Surron Ultra Bee Triple Clamp, 6061-T6 upper and lower clamps for the OEM KKE fork with a 15mm rise bar clamp; Surron Ultra Bee Headset Bearing Kit, the OEM replacement bearings, races and seals; and Ultra Bee Suspension Linkage Bolts, 420 stainless full shank bolts with grease ports, three linkage and two triangle bolts per set.

Talaria and Ventus One+ Forks

Sirris F43 CMX Fork for Talaria MX5: the 220mm F43 for the MX5 only; the MX3, MX4 and X3 are not covered by it. Sirris F43 CMX Fork for Ventus One+: the same 220mm chassis set up for the Ventus One+, with compression adjusted by hand at the top of the leg.

Arctic Leopard Suspension

Sirris F43 CMX Fork for Arctic Leopard XE Pro S and Enduro ships with a 220mm rotor bracket and a black billet drop clamp. Sirris F43 CMX Fork for Arctic Leopard XE Pro R carries a 240mm rotor bracket to match the R's front rotor.

Sirris R38 2SC Rear Shock for Arctic Leopard XE Pro: one 269 x 68mm shock for the S, Enduro and R, run through the TMB R38 linkage, sold separately.

EXT Ferro Air Fork

EXT Ferro EMX Air Fork: 205mm of travel on an HS3 air spring, 36mm chrome moly stanchions, and independent high-speed compression, low-speed compression and rebound. It uses boost hub spacing, so most bikes need a boost rotor spacer, and the Eride Pro SS 3.0 takes the EXT brake adaptor. It does not fit the Talaria MX5.

Cockpit and Shock Protection

Surron Light Bee Stem Lock Kit: stainless through bolt, CNC aluminum lower clamp, upper cap and spacers. Surron Handlebars 3" Rise: twin wall 7075-T7 aluminum, 780mm wide, 31.8mm clamp, bolting into the stock clamps. FactoryZ Shock Cover: 4mm neoprene cut for a 265mm shock, wrapping on with the shock still in the frame.

Sirris Suspension FAQ

Is every Sirris F43 fork the same part?

No. The 220mm F43 shares one chassis, but each listing carries its own spring rates and, where the bike needs it, its own brake bracket and wheel spacers. The Surron Ultra Bee version is a longer fork with 246mm of travel. Order the listing named for your bike.

Do the Sirris R38 shocks use my stock linkage?

No. The Eride Pro SR and SS 3.0 shocks run the Prickly R38 linkage, and the Arctic Leopard shock runs the TMB R38 linkage. Both linkages are sold separately. On the Eride Pro, the R38 linkage raises the rear 25mm, and the F43 drop clamp raises the front the same amount.

How do I pick a spring rate?

Go by your weight without riding gear. Sirris already counts 15 pounds of gear into every range. Each product page lists its rates as left side / right side.

What does the Light Bee X need for the F43?

A 220mm front rotor and a 4-bolt direct mount stem. The fork ships with the 220mm brake bracket; the rotor and stem are separate.

Does anything here fit the Surron LB2?

No. The LB2 is a new frame and a new design, not a Light Bee. The Light Bee parts on this page are for the original Light Bee, not the LB2.
