Back in the 1980’s when I had my first Suzuki I joined the SuzukiOwnersClub. Apart from the key ring didn’t get much out of it. The meets were not very regular and far from me.
Later on when I got the Kawasaki GPX750 I joined the KWAKS OWNERS CLUB.
Initially set up as a group for GPX and GPZ bikes but soon opened to all Kawasaki models. Was a good group, regular news letter sent out. several ride outs each year. We always had a stand at most of the classic bike venues, Stamford, Peterborough and many others. I did go and do stand duty on many times.
for me it was a sad time when the club unfortunately folded. There was tons of Kawasaki bike information lost. It briefly re surfaced on FB but that soon fell out of use.
Since the demise of that group never bothered joining another owners club.
