I don't know how bad it is, but I had a small rattle that over time became an actual banging I could feel, but only at low speeds. I tightened the chain, but it didn't help all that much. I put the bike on the centerstand (a must-have add on) and saw that the chain was binding at a certain spot. Lubed the chain, problem gone! I originally thought it was something really major- it eventually shook the bike quite a bit- but turned out to be no big deal. I find the chain needs to be lubed every 300 or so miles.
