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 made from stainless steel and have the shallow recess on the top for the decal.
These fork top nuts are manufactured in the UK, and are threaded to fit the internal-spring forks from 1971-1972. 20 TPI.
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.
