Bought a low mileage Honda CB500x.... 2 years old with just 6,500 km. Main problem clearly is lack of use and it has been standing unloved for many months. Tyres need replacing as they feel real hard. Obviously all fluids need checking/ changing. I have two major worries though. First is the chain has bugger all oil and a light surface rust. It would be good to return to service . Wire brush then lube? Replace? Second problem is general cleaning. Most is just a matter of a scrub but under the seat is very dusty. I am tempted to hit it with a hose but fear the result, especially with fuel injection and abs. Blast with compressed air?. A paint brush will not reach it all. Suggestions please.
