I have a pair of NOS, boxed 12.9” Girling shock absorbers p/n (stamped) 64052487A ED21 for sale. They are specified for the MX models, I guess the spring rate and possibly the damping is slightly different from the road models (including Triumph Adventurer). There is a small rust mark at the base of one spring. I guess they would be described as shop-soiled but I’ve yet to clean them up. I’ll load-up some pictures when I get a chance.
Please let me know if you are interested before I put them on fleabay.
Thanks, Robert
