Does anyone know of a better/bigger rear seat for the Dragstar 1100,or is it possible to put a front seat on the rear?

I am told it is a bit uncomfortable on a long ride.

Do you already have a backrest? This can help.

Failing that, there are loads of custom Cruiser accessory companies around, some of whom offer various different seats. Search for the Touring range of stuff, as they're often bigger and comfier. Most will be in America though, so either expect high postage and import costs, or look to have a custom one made up from a UK company.

Getting short outriggers to extend the pillion pegs can also help in making the seating position and weight distribution a bit eaiser on yer back-seat babe!
