Average number years you own a bike

[Nortoon_imp]

During my first 3 years of motorcycling I changed motorcycles every year.
I modified a BSA Lightning into a café racer and kept it 3 years.
After that I went back to my yearly changes for another 3 years.
Restored a 1971 BSA Lightning and kept it 3 years.
Bought a 1980 Yamaha 1100G and added a lot of Vetter touring accessories to it.
Traded it in on a 1982 Honda Aspencade and kept it 7 years.
Had a 25 year hiatus from motorcycling and bought a CB500XA in 2014.
Traded it in on a 2017 CB1100 EX which I have kept.
