there is a fairly clean 76 it400 for sale I've been eyeing. The bike is complete and in overall good shape. I know this is the first year of the IT . I already have an IT200 and 250 from the 80s. I thought it would be cool to add a first year bike to the collection. Any reasons not to get it. Is this bike at all collectable? my plan would be to restore it and ride it once and a while.
