Engine displacement is 100 cubic inches and has a
9.6:1 compression ratio. The engine and transmission are tilted four degrees to
give the bike a more aggressive look, allowing room for the gas tank in between
the neck and the engine and also raising the transmission to keep the drivetrain
aligned. The transmission is a six-speed unit with fully back-cut gears and its
case modified to delete the starter. The primary drive started out as a
Primo/Rivera enclosed system and is modified to incorporate a slender belt that
continues with the typical look of the era. Under the belt side cover are the
voltage regulator, oil filter and shifter components. The swing-arm pivot point
is in front of and below the transmission. The top of the swingarm enters into
the frame as the suspension is compressed. Attached is a hidden linkage and
support shaft that connects to the shock, while a custom-made belt tensioner
maintains constant final drive-belt tension. To retain an exposed and open
look above the transmission area, the bike is kick-start only, so no bulky
battery and starter motor need apply. Important to Goldammer was
maintaining the smaller, contoured bicycle-type seat. Sparse in appearance, it
is surprisingly palatable given the camouflaged suspension system. The
Springer front end started out as a W&W VL reproduction. A five-degree and
0.75-inch offset top and bottom tree-set was built to correct steering geometry.
The traditional turn-down handlebar configuration is designed with a clean
unobstructed appearance; the handlebars house an internal throttle assembly and
a master cylinder for the brakes. The rear master cylinder is borrowed from a
Honda dirt bike and was mounted to the left side of the transmission. The
authentic two-piston calipers come courtesy of Performance Machine, the hardened
and ground stainless rotors are 20.5 inches in diameter, a size large enough for
plenty of stopping
power. (Click image to enlarge)
For lighting, Goldammer utilizes exceptionally bright LEDs. The housings
(two for low beam, one for high) also serve as heat sinks for the lights. At the
rear, flush-mounted brake lights, running lights and self-cancelling turn
signals are set into the back edge of the seat—present-day amenities integrate
well into its minimalist theme. Approaching all fabrication as a sum of the
whole, the BTR3 is truly an outstanding example of determination and
award-winning vision that sparks the spirit of history in an elegant,
contemporary two-wheel portrayal. 250.764.8002
