do a search for suzuki trikes, this has been discussed a few times on here. suzuki trikes that is. from what i have read, suzuki only had the early alt models, 50, 125, and 185 i believe. suzuki never had a factory trike racer. they were one off custom made bikes. mainly rm's converted. never heard of a 350, but then again anything is possible. try and get some more info on this thing, maybe some pics to post up and we can go from there.

Life's journey is not to arrive at the grave safely in a well preserved body, but rather to skid in sideways, totally worn out, shouting "HOLY SH-T, what a ride!"
