Today on BikeBound.com: 1700cc Single! “Hackel-Wright” chopper by @alhackel, built around a single jug off a 975 c.i. (~16,000cc) Wright R975-46 9-cylinder air-cooled radial helicopter engine!
This was the ultimate refinement of the Wright-designed, Continental-built 975 Whirlwind engine that powered the Sherman tank, Beechcraft Staggerwing, Curtiss Sparrowhawk, UH-25 Army Mule, and much more.
@alhackel originally planned to build a Knucklehead till he learned what that would cost.
“I found the [Wright] cylinder head on ebay and thought it was pretty neat looking so I decided to build a motor around it.”
Al had to make a custom case, conrod, and 5-piece crankshaft for the engine. Justin Leineweber (@leinewebercambuilds) ground the custom cam and @maritimerglassworks blew the trick glass headlight, taillight, velocity stacks, and shift knob. Make sure to swipe for closeups! 🐙🧐🔥
What’s it like to ride?
“Equal parts abject terror and unbelievable euphoria. It will shake your fittings loose, but tracks smooth down the road.”
The Hackel-Wright was featured at both @handbuiltshow and @the1moto.
