A couple of years and 50,000km under my belt and I've been through a few tyres, a couple of chains/sprocket and many other consumables for services. My riding is 95% commuting, rain hail or shine, so a different ride profile to a quick blat on weekends. The CB500F is a good little commuter for me. It's no powerhouse, but consistently gets 400km out of a tank, and is comfortable enough for my ~130km daily commute. However, with a fail-to-proceed through a chain failure a couple of weeks back, my mind turned to what is likely to break next, and what I can do to ensure it too doesn't result in my being stuck on the side of the road. Regular servicing is a no brainer, but for the grey beards of motorcycling, (and I know this is a 'how long is a piece of string' question) what major things start breaking on bikes after 50,000 or 100,000 or whatever the number is? Thanks.
