The Rickman Honda CR I am restoring was a race machine for many years. The rear coil/ shock units are lightweight alloy body with adjustable spring platforms (see photo). They have air assist, not leaking, and no oil stains! Searching around (and with help from suppliers on this site), I’m guessing they are WORXSHOCKS.
I’ve sent them enquiries, but no responses. Is anyone using their products, where were they purchased? Do they sell parts or rebuilding service? What are the typical ranges for air pressure? Thanks, in advance. Any info appreciated.
