With motorcycles, what are the parts that most frequently get damaged and therefore have to be exchanged most frequently?
I'm asking this question because I am looking to buy a motorcycle that I would like to maintain and repair myself. One factor for deciding for a specific model will be the availability of spare parts. Therefore it would be good to know which spare parts will be needed most frequently so that I can then do some research on the availabilty of these parts.
By the way, I am going for an older motorcycle, most probably a Japanese one (e.g. Honda CB series from the 1970s or 1980s).
