We've been quiet this summer and we apologize for that, we have been very busy and the new boss takes his quality control very seriously!! If something isn't right, he nips at your ankles! 😅
Here's a picture of Tater inspecting the install and quality of this lower end before we assemble. He wanted to make sure that lived up to his standards, he had doubts. He said something about dogs are smarter than horses or something. He was wrong, its perfect!! Lol
The Lake of the Ozarks bike fest is right around the corner. Be sure to check your tires, brakes, oils, etc... There's plenty of time to get in beforehand! Until then ride safe!

A dark horse is the one nobody expects. The sleeper. The quiet threat that shows up, digs in, and blows past the favorites. That’s always been our mentality in the V‑Twin world. Stay focused, stay sharp, and let the results speak for themselves.

The name also nods to one of the greatest racehorses in American history: Man o’ War. An absolute powerhouse. 20 wins out of 21 starts. World records. Pure grit and dominance. We started naming some of our products after him because he represented performance you couldn’t ignore.

That’s the spirit behind Darkhorse.
Built to win. Built to last.

If you ride with us, you already know.

233.742 MPH. Fastest Harley-Davidson in History.

Darkhorse Motor Company congratulates Hiro Koiso Racing on setting a new AMA national record of 233.742 mph in the 3000 APS‑PBF class at the Bonneville Salt Flats, officially the fastest sit‑on Harley-Davidson ever recorded.

The JIMS/T‑Man 135ci Twin Cam, ProCharger boost, JIMS FAT6 transmission, WPC‑treated internals, and Worldwide Bearings all come together to put serious power to the salt.

This achievement is a testament to what focused engineering and relentless refinement can accomplish. We at Darkhorse Motor Co are always proud to see Harley‑Davidson performance pushed to its absolute limit.
