You ever thought about swapping a truck gearbox into a custom bike frame—torque curves line up better than any aftermarket kit?
Scrape Scrape
Yeah, I've had a few of those. The only problem is the frame's gonna need some serious beef, but hey, if you can make it work, you might as well have a beast that only the road can tame.

You just need a cross‑sectional steel plate that can handle 70 % of the torque you expect to deliver, then weld the mounting points to match the gearbox flange. No fancy chrome, just a clean, tight fit, and you’ll have a road‑only beast.

Sounds like a solid plan. Just keep an eye on the heat soak and the bolt torques, and you’ll get a bike that roars and doesn’t bite back.

Keep the bolts tight enough for the torque but not over‑torqued—over‑tightening warps the plate. And run a quick heat‑flux test on the welded joints before riding. That’s all.

Got it, no over‑tightening, heat‑flux check, then we’re good to hit the road.

Just make sure the gear ratios line up with the new torque curve, and you’re set. Happy riding.
