1926-1984 Vintage Models
Flathead Power ®
Anders Nygren Signature Series Engines
for big twins
Limited Edition! Only 25 will be Made!
The Anders Nygren Signature series engines pay tribute to the founder of the original Flathead Power company, Anders Nygren.
Anders started Flathead Power in Sweden in the early 1990s mainly to provide impossible to find parts for his own vintage race bikes.
His accomplishments as an engine builder and engineer were nothing short of amazing as he, for the most part single handedly,
built his fledgling business into an internationally known source for vintage reproduction parts for restoration and retro custom
motorcycles. Unfortunately Flathead Power fell victim to a turbulent economy. Rather than allow Flathead Power to fade away, S&S
Cycle purchased the company name and assets in 2007. Since then S&S has worked hard to bring the name back to life, but we
haven't forgotten the man who got it all started.
These KN-Series engines are available in 93 cubic inch displacement only, and feature Ander'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.

Alternator/generator cases have 1948-’99 style front motor mount. Will not fit
stock knuckle frames.
Generator style engines have stock motor mounts for 1936-’47 style frames, but
can be used in 1948-’99 style frames with front motor mount spacer, part #31-2017
(included).
Alternator/generator cases require a transmission with 1970-up length mainshaft,
and custom exhaust pipes must be fabricated.
The dyno shows that although the KN93 does not make big top end horsepower, it has
good low and midrange torque. This is an excellent engine for cruising.
