You ever thought about swapping a truck gearbox into a custom bike frame—torque curves line up better than any aftermarket kit?

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.
