Depends on what you call heavy. Heavy for me is big Harleys, Euro cruisers and other road bikes. I cant stand heavy bikes like that which are awkward to move. No that BSA wont be as light as a 1970's 2 stroke but i dont consider it would be a massive struggle to manouver it around during its intended purpose unless you were a 10 year old kid. Thats what people raced back in the 40's-60's though. I think it looks kinda good.
