Durring my recent trip to death valley my my upper chain guard and lower chain guide seemed to spontaneously self-destruct. I suppose a rock or something must have got caught in there. I have a moose lower chain guide on order for the one under the swing arm. The upper chain guard as far as I know is only available from suzuki and a guy in Germany who makes them out of stainless steel:huh. I noticed that most dirt bikes do not come with the upper chain guard, but all dual sports do. Do you guys think this is really useful? I'm guessing that they only put those on street bikes to keep passenger feet away from the chain?
