Engine Building – We Don’t Build Motors. We Forge Straight-Up Machines.
You want a motor that lasts? Cute. We build engines that dominate, destroy, and send the competition home crying to their mommas.
Every single one is wrenched together by hand, right here on American soil, with nothing but the best U.S.-made parts. No cheap Chinese cranks, no mystery cylinders, no “budget” bullshit that grenades the first time you lean on it. If it carries the TMF name, it’s built to take a beating and spit fire right back.
What rolls out of here on the regular:
- 107" sleepers that embarrass 114s
- 128"–132" street killers that eat tires for breakfast
- 143"+ full-race monsters that make grown men whimper
- Sky-high compression, monster cams (Wood, S&S, Andrews, Cycle-Rama, Reaper—whatever chews the hardest)
- Heads ported so hard the flow bench begs for mercy
- Full 30–40° raked baggers with 150+ hp mills that still ride like they’re on rails
- Turbo kits and ProChargers that turn rear tires into smoke signals
Every TMF build gets tortured before you ever touch it:
- Dyno break-in until it’s begging
- Verified horsepower/torque sheets so savage you’ll frame ’em
- Full documentation
Dream it? We’ve already built it twice this week—and made it faster than your wildest drunk fantasy.
Bring us your fantasy. Walk away with a fire-breathing beast that’ll smoke your buddy’s “built” bike so bad he’ll sell it and buy a Honda.
TMF Engine Builds – Built in America. Feared everywhere else.
