Hi Tony, there's lots of info on here relating to ammaco including scans of brochures adverts etc do a search for ammaco and you will find loads of info, they did many different models over the years with different specs and decals etc. We need to know which model you are interested in to give specs etc.
All the freestyle bikes they did except for the styler 500 and the freestyle 18 were based around the same frame which is the one in the pic there were mods to the gusset over the years but thats all. (the one in the pic is the latest gusset arrangment).
