Picked this up while on a job assignment. Very little info about Karate bikes. There was an earlier thread on this board but not much known. Apparently made by "OxJap" company. I guess mid-80's? Never heard of the type of Shimano derailleurs these are but they seem to work fine. Diacompe brakes work great. Chromoly-Steel. Interestingly the bike on the earlier thread had a sticker from an Atlanta bike shop that was only a few miles from the guy I bought this from, when also used to work in a bike shop.

Anyone have experience with these? It was only $75 so I thought it was worth a gamble
