Bentrod, I can't comment on the 'Norton' Corbin but I bought a Corbin for my Suzi DRZ400 and was dismayed at the weight, for my bike Corbin uses it's own chopped glass/resin pan and it's thick and hvy. I sold it on and had the stock pan reupholstered and the foam widened 1" each side. For the price and wt., I think I'd want someone that has a Commando seat version to respond, mine wasn't what I had in mind ...Mark
