I would go visit an upholstery shop that specializes in motorcycles and ask them to build you something custom. You can call Corbin, and they are known for making a nice saddle, but having a saddle identical to someone elses Corbin isnt exactly "custum"
A member on here named "Lunatic Fringe" makes LED light kits for all Buell models. He also builds extended swingarms and can modify your rim to accept a 240 tire.
