A limited edition of 25 Anders Nygren Signature Series Engines is for sale by S&S Cycle. Anders Nygren is the founder in the 90’s in Sweden of the original Flathead Power Company, mainly to provide impossible to find parts for his own vintage bikes. His accomplishments as an engine builder and engineer were nothing short of amazing and he moved his business in Louisiana under the name of vintage reproduction parts for restoration and retro custom motorcycles. In July 2007 I reported that victim of a fledging economy the company stopped business and S&S Cycle bought the Flathead Power name and all assets.
S&S Cycle has worked hard to bring the name back to life, but has not forgotten the man who got it all started. These KN-Series engines are available in 93 cubic inch displacement only, and feature Anders’s signature CNC engraved on the gear cover, chrome knuckle tin covers, and the Slasher air cleaner cover on the Super E carburetor. Choose from generator style crankcases for stock style chassis or alternator/generator style crankcases for custom applications.
