Black Sky

SEL-MOTION Motorsports is pleased to present: Project Black Sky. The 2004 Bonneville Black was formally the demo bike at Triumph Detroit and later sold to a local customer of ours who cafe'd the bike to his own tastes. The bike was returned to stock before being sold with the take-off parts being sold on eBay to help subsidize his new bike purchase. The bike has 51,000 miles on the clock and is as tight as a new bike. The former owner took very good care of it and had the dealer service it including shimming the valves recently. The bike presents very well, has been properly sorted and comes with full service records.

Before tearing the bike down for conversion, I replaced the tires, brakes and wheel bearings and took it in stock trim to the Smokey Mountains in NC to ride. The bike performed flawlessly showing no signs of wear-and-tear. Upon my return, I started the process of dismantling the bike down to the engine-in-frame, and not much else. This allowed me to perform a proper cleaning as well as giving me easier access to replace corroded fasteners. The cylinder fins were painted black prior to reassembly.

SEL-MOTION offers complete turn-key conversion motorcycles. This motorcycle is shown for the example purpose of what can be built.  The motorcycle as-shown has been sold, but can be reproduced to the customer's specification.
