Interested to know if anyone has fitted a fork gaiter kit to the Thunderbird Sport? Noticed that Triumph do a kit for the Thruxton Bonneville Scrambler. Thunderbird sport fork diameter is 43mm against 41mm for the Thruxton. I can find no diameter for the top of the lower fork leg that the gaiter would clip over for the Thruxton. Anybody help me out with that dimension please?
