this is the one I would get.
https://www.techeblog.com/tower-trike-largest-motorcycle/SRK Cycles’ Tower Trike is currently the world’s largest motorcycle, and some describe it as a semi-tractor-trailer merged with a bike. Weighing nearly 11,000-pounds, it’s powered by a twin charged (turbocharged + supercharged) diesel engine generating 335 hp and 1,110 lb-ft of torque. There’s a 200-pound metal cross on the back as a design choice, but doubles as a roll bar in case of an accident. One caveat: it’ll set you back $90,000 to get your hands on this beast.
