Hey guys...new here and I have a question about the rear shock spring. I have an '06 XB12R that I purchased recently (I am the third owner) and noticed that the rear shock spring is yellow with nothing stamped or written on it. I'm pretty sure the stock spring for this bike is supposed to be blue. I was just wondering if this might be a stock spring with a different rate offered by the factory or an aftermarket brand?? The guy I bought the bike from hasn't added anything to it. He did tell me that the original owner added a Jardine exhaust and that's about it. The spring does not look like it has been repainted. Any input would be great. Thanks!
