Hello KOZ, Yes, Fox Campus bikes did come with 3,4,5,hp Briggs motors. Here are some details about the Fox bike you're looking at. The motor has been repainted and is not original.....thehe recoil is facing in the wrong direction. The footpegs are home made out of water pipe. The seat is not original. The tail light is the wrong style for that year and not original. The color is definitely not original. Should be HiFi blue. Fork boots are shot. Headlight has been painted. Should be all chrome. This bike was made somewhere between 1962 and 1965. Fox did make a few models with steel fenders and steel chainguards but not this one. The chainguard on this bike is original but somewhat beat up. The rear shocks have seen better days. I'll be glad to answer any other questions that you might have. Ogy
