2009 Thunder Mountain Custom Cycle, Keystone 300mm

Customer Mike Mantha brought this bike out from Texas to have us build a custom rear seat system for his Keystone. There is limited parts available for this popular discontinued motorcycle. We at BSC get calls weekly regarding this particular problem of the discontinuation of the seat and sissy bars.  

Thanks to Mike we now have a mold and fixturing to recreate seats and sissy bars for this model. No need to ship your bike to us in California, we can now build you any version of a sissy bar and seat combo that can be dreamed up. Description of seat styles below.

1.  One Piece King and Queen seats with tall or short sissy bars. Bars can be pointed, rounded or square shaped as in this model. The King and Queen seat would the optimum seat for style and comfort on this chopper.

2. This is a version of the two piece king and queen with lumbar. It has a medium height sissy bar in a squared original Thunder Mountain shape. This bar originally was designed for a one piece two up seat that sat down on to the paint. We modified the design similar to the Heartland rear seat systems so that the seat and sissy bar can be attached together and as a full assembly, then mount to the Heartland struts that are stock on this model bike. It also can be removed easily. One of the other key reasons people like this system is for the fact that the seat never touches the paint on the fender, lessoning the probability of scratching. 

3.  The three piece seat system is also an option for look and convenience. Solo drivers seat, pillion pad and separate back pad.

                                                               You call it we can make it. 

                              From custom bike accessories, wheels, sissy bars to exotic seats.
