Sirris F43 CMX Fork for Talaria MX5 | 220mm Travel

This Talaria MX5 fork is the Sirris F43 CMX, a 220mm upside down fork with 43mm stanchions and MX-grade seals and bushings. It is the MX5 version only; the MX3 and MX4 are not covered by this listing.

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.
• Spring rates for the Talaria MX5: Medium 3.6/3.6, Heavy 4.0/3.6 (left / right) - sized to this bike, not a one-rate fork.
• Sirris part family 430-99-020.

Sirris F43 Fork FAQ

Which spring rate do I pick for the Talaria MX5?

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.

What does CMX tune mean?

CMX is Sirris's Compact Motocross Tune. It is the damping setup built for small, light E-motos ridden hard, not a full-size motocross valving shrunk down.

Will it take street tires?

Yes. At 178mm of fork spacing the F43 clears dirt or street tires, so a supermoto setup works on the same fork.

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.

What does the drop clamp do?

It adds 25mm of extended length. That extra length is what makes a 21 inch front wheel conversion possible.
