I was sideswiped by a cyclist on the on ramp to 205 south as the rider attempted to pass on the right. We stopped and as I returned to my vehicle to retrieve my phone to phonograph our DL's and Insurance, the rider left the scene. Not being a rider I sleuthed together that his bike was probably a Yamaha (tuning fork logo), flat black, chrome trim(no Color) with SHAD side bags. His left side bag was damaged and detached form the cycle. He did $1815 of damage to my passenger side fender. Any help to ID this guy who gives riders a bad name would be appreciated. As a non rider I always give bike diving legally space as what ever I drive it is bigger that the bike/rider and I understand physics. Best wishes for a long riding season.
