I just bought a 2005 black RC51 with 3k miles on it. The battery had to be repaced because the original owner had so many bikes he never got around to running the RC. However, it came with a slighty softer sprung front fork with new valves, new springs and new rings. The rear suspenstion is a Wilbers shock which is fully adjustable. A power commander and a new set of pirellis as well. It rides like a dream and really has some time warping power.
