I am starting a little cafe racer project and am not sure of the modification laws in Victoria. Can you use an engine in a different frame by the same manufacturer. ie, Yamaha DT 175 engine in a Yamaha TT350 frame. Also can you use a different front and rear end, ie Honda NSR 250. I would appreciate some info on what is or isnt allowed. Tried reading Vicroads info but I'm not very good with gobledegook.
