New production, quality mainstand rubber will fit a multitude of motorcycles! For use on Triumph, BSA singles, twins and triples.
Restore proper function and protect your frame with this Triumph mainstand rubber, part number 57‑2331, designed for classic Triumph T120 and T140 Bonneville, TR6 Trophy, Tiger, and T100 models. This rubber stop fits the mainstand (center stand) and provides a cushioned contact point when the stand is retracted, helping prevent metal‑to‑metal contact and chipped paint on your frame.
Over time, original mainstand rubbers harden, crack, or disappear entirely, leaving the stand to bang against the frame and exhaust when folded up. Replacing the rubber with the correct Triumph 57‑2331 part restores smooth operation, reduces noise, and helps protect your bike’s finish. This is an essential small part for any thorough restoration or service of the center stand assembly on a vintage Triumph twin.
Manufactured to the correct dimensions for easy installation on the mainstand, this rubber is suitable for street riders and restorers alike. It is a simple, inexpensive upgrade that makes a noticeable difference in everyday use. Pair this mainstand rubber with fresh stand pivot bolts, springs, and hardware to ensure your Triumph center stand operates as it did when new.
Check your Triumph parts book to confirm 57‑2331 as the specified mainstand rubber for your model and year, and verify the quantity required. If the stand snaps up harshly or contacts the frame directly, this rubber is likely missing or overdue for replacement.
