Sirris F43 CMX Fork for Eride Pro SS 3.0 | 220mm Travel

This Eride Pro SS 3.0 fork swaps the stock front end for the Sirris F43 CMX: 220mm of travel, a sealed closed cartridge, and hand-adjustable compression. Pair it with the Sirris R38 SS 3.0 shock for a matched setup.

Specs:

• 220mm travel, upside down architecture - full-size MX layout on a lightweight E-moto chassis.
• 43mm stanchions in high tensile steel with hard chrome - stiff legs that track straight under braking.
• Seamless 7050 aluminum outer tubes and damper bodies, type 3 hard anodized - resists scratches and wear.
• 775mm free length; the optional drop clamp adds 25mm - room for a 21 inch front wheel conversion.
• 178mm fork spacing - clears dirt or street tires.
• Symmetrical closed cartridge damping with dual oil circuits - lubrication and damping oil stay separate, so the feel stays consistent lap after lap.
• Hydraulic bump stop - controls bottoming on big hits without giving up stroke.
• Tool-free external compression adjuster; rebound adjusts with a tool - dial it in at the trail.
• Billet 6061 aluminum triple clamps, type 2 anodized; seamless 7050 aluminum steer tube.
• Motorcycle-style top cap - sets steering bearing tension more consistently.
• NOK MX seals, Daido MX bushings, 210 degree high impact PP guards.
• 4kg per leg.
• Clamp options: Standard clamp in black or blue, or the drop clamp in black or blue.
• Spring rates for the Eride Pro SS 3.0: Medium 3.6/3.6, Heavy 4.0/3.6 (left / right) - sized to this bike, not a one-rate fork.
• Sirris part family 430-99-024.

Sirris F43 Fork FAQ

Which spring rate do I pick for the Eride Pro SS 3.0?

Pick by rider weight without gear; 15 pounds of gear is already built into the ranges. Medium covers 140 to 180 pounds with 3.6/3.6 springs. Heavy covers 180 to 220 pounds with 4.0/3.6 springs. Rates are listed left side / right side.

Does it pair with the Sirris R38 shock?

Yes. The R38 is tuned to pair with the F43 CMX fork. Its linkage raises the rear 25mm, and the drop clamp raises the front by the same 25mm to keep the bike level.

What can I adjust without tools?

Compression adjusts by hand on the outside of the fork. Rebound uses a tool. Sirris recommends about 5 hours of riding before you make big clicker or valving changes.

Which stock parts carry over?

Your stock upper steering bearing, split race, and seal stay on the frame. The brake bracket bolts on with M6 bolts at 18 Nm.

Do the weight ranges include riding gear?

Yes. The ranges are your weight without gear, and Sirris has already added 15 pounds of gear into each range. Weigh yourself in street clothes and pick from there.
