Ron give these people a try. Don't know if they will have what you are looking for but I am sure they could direct you in the right direction.
I did a quick Google search and it didn't show much in NSB you might have to go to Daytona to find the type of bike that you like.

Ron I guess I should have read your post a little closer and paid more attention (my bad). You might contact these folks and get some help. Every Sunday, a group starts at the corner of Live Oak and Canal Streets (on the mainland downtown) at 8:00 a.m. The ride is 46 miles at a 19 to 23 mph pace. Parking is available in the adjacent lot for the New Smyrna Beach Utilities Commission. There's a stop at a convenience store about 20 miles into the ride - a second stop if anyone needs it at about the 30-mile mark. The route can be found here -> http://tinyurl.com/cnrenj A 30-mile version is held Wednesday and Friday mornings, also at 8:00 a.m. starting from the same place. Interested?
