Refresh the action and return of your Thunderbird’s rider pegs with the genuine Royal Enfield 594334/C – NT51 Spring, Rider Footrest. This is the OE torsion spring that loads the rider (front) footrest so it returns to position after folding on contact and stays solid while riding. Because it’s an OEM part, the wire gauge, leg length, coil count, and winding direction match factory spec, giving you the correct preload and peg feel—something generic springs rarely achieve.
We verified this part as “NT51 SPRING RIDER FOOTREST” and “Ressort repose-pied (rider footrest spring)” in trusted Royal Enfield parts indexes and dealer lists. Confirmed application is the Thunderbird family (often labeled NTB 350 / NTB 500 in catalogs). Use one spring per peg; order two if you are refreshing both rider pegs, and pair with the correct Rider Footrest Assy RH/LH if your hinges are worn (RH 594118/A, LH 594119/A shown in adjacent NT51 listings).

FAQs
Q1. Is this for rider or pillion pegs?
Rider (front) pegs. Pillion pegs use different hardware.
Q2. How many springs do I need?
One per rider peg. Refresh both sides for symmetrical feel.
Q3. My listing shows “NT51”—what does that mean?
“NT51” is the OE design family used across Thunderbird footrest hardware.
Q4. Will /B and /C both work?
Yes—/C is the current revision; some inventories show /B. Both are listed as the NT51 rider footrest spring.
Q5. Symptoms of a bad spring?
Peg doesn’t return after folding, feels floppy, or sticks half-open.
