Once owned by Sammy Miller in the U.K., the 1930 Brough Superior 680 Black Alpine — so named for its all-black finish — was impeccably restored and is now cared for by Don Rosene of Alaska. Hand-crafted leather toolboxes were stitched in England.

A trade and some cash netted motorcyclist and collector Don Rosene of Anchorage, Alaska, this exquisitely restored 1930 Brough Superior 680 Black Alpine. Granted, it wasn’t so nicely restored when he acquired it some 25 years ago, but it was a motorcycle with history, and the machine deserved a complete resurrection. Don wasn’t in a rush for the Brough Superior to be finished, but like many important things, it took time for the project to reach a conclusion.

Don began his riding career at 12 years old aboard a diminutive 1.5-horsepower Doodlebug scooter, first rolling down the alley behind the family home in Rockford, Illinois. When he turned 14, he got a Cushman scooter. “Then, when you’re 18, it’s not cool anymore to ride a scooter,” Don chuckles, and continues, “You’ve got to get a car so you could have a gal sit next to you.” He went away to college but returned to motorcycles in 1963 with the purchase of a 305cc Honda Super Hawk. The Honda was traded the next year on a 650cc Triumph Bonneville, and that taste of British torque led to a succession of the parallel twin machines.
