Triumph BSA 650 Twin 750 Triple BSA B50 71-72 Conical Hub Fork Top Nuts Plated Pair 20TPI PN# 97-4258

Description

These fork top nuts are of the one-piece design that was originally used on the 1971-1972 oil-in-frame 650 models, 750 triples, and BSA B50. They are plated and have the shallow recess on the top for the decal.

Economical plated steel fork top nuts are corrosion-resistant. 20 TPI fitment for use in the 1971-1972 conical brake forks. Will fit 1971-1972 BSA and Triumph 650 and 750 models along with 1971-1972 BSA B50.

The one-piece fork top nuts have the extended tip to locate the internal spring. They are tightened down using a large spanner and seal the fork oil in the fork tube and secure the instrument mounting brackets.

Sold in pairs, replaces OEM PN# 97-4258 97-4395 & 97-4387 and yes, these do replace both the inner and outer fork top nut on disc brake Triumph forks for a cleaner and easier installation.

IMPORTANT NOTE: These top fork nuts are 20 TPI with thread OD 1 3/16th” (1.187″). Check the TPI of your forks before purchase to ensure fitment of these top nuts. See recommend links for a thread pitch gauge.
