I bought my 2013 CB500F with 13,500 km on the clock, Feb. 2015. Since then, I have changed the oil and filter each 10,000 km, and chains, sprockets, tires, etc. as required. No other servicing was performed until 100,000 km, when I took it to a mechanic, with instructions to check it over and replace anything necessary, ( spark plugs, air filter, brake pads). Valve clearance needed no adjustment, and we could have gone further on the spark plugs, but why would we. I have replaced one headlight bulb and one taillight bulb, and the battery at 155,000 km, and that is all. It has now traveled 166,000 km. It has been ridden in all weather on all kinds of roads, main highways to forestry tracks, and has never once let me down. I have never needed to add oil between changes. It still runs as sweetly as when I first acquired it and has no rattles or other undesirable noises. and while not pristine, still looks bloody good. BEST BIKE THAT I HAVE OWNED. Has anyone done better than this?
