YouTubers Stuff a 200-HP Hayabusa Engine Into a Plastic Truck: From Toddler Bed to Death TrapMotorBiscuitRahaan MazumderTue, September 22, 2026 at 3:30 PM UTCAdd us on GoogleWhat happens when you combine the heavy-duty plastic of a children's car bed with the terrifying 200-horsepower output of a legendary Suzuki Hayabusa motorcycle engine? You get one of the most absurd, dangerous, and brilliantly engineered DIY race cars on the internet.Following the massive success of their 130-horsepower Corvette bed build last year, the automotive creators at the BUM YouTube channel have officially outdone themselves. Their latest project involves a bright red, heavy-duty plastic truck bed, a custom-welded steel frame, and enough motorcycle horsepower to comfortably hit highway speeds in a piece of bedroom furniture.The crazy build kicked off when the team stumbled across a rare find on Facebook Marketplace. "Most beds that look like a car are made out of cardboard, and the good ones are really hard to find," the host explained. "It just so happens that the same company that makes our Corvette bed also makes a truck, and one of them showed up… and we bought it".But simply strapping an engine to a plastic bed isn't going to cut it when you are pushing 200 horsepower. The team had to fabricate an entirely new, custom steel frame from 80 feet of tubing to handle the immense stress and speed of the upcoming powertrain.AdvertisementAdvertisement"We're going to build our frame narrow, have A-arms on both sides, and then in the back our frame will have some sort of hoop that's going to allow our solid axle to move up and down," they mapped out, ensuring the new truck bed would have proper racing suspension.The 200-HP Hayabusa HeartThe true madness of the build lies under the plastic hood. The team managed to squeeze a massive, high-revving Suzuki Hayabusa motorcycle engine into the front of the tiny truck frame.However, unlike their previous Corvette build, they made a massive engineering pivot for the sake of safety."On the Corvette, the engine is… transversely mounted," the host detailed. "What that makes us do is use the chain setup from the motorcycle. And I don't know about you guys, but having this really long chain right next to your leg going 120 mph is pretty sketchy".AdvertisementAdvertisementInstead, the BUM team mounted the Hayabusa engine longitudinally—the same way you would mount an engine in a Mazda Miata or a Nissan 240SX. This allows them to use a custom jackshaft to run a real, solid drive shaft straight to the rear axle, eliminating the terrifying "chain-next-to-the-leg" hazard.After notching the plastic body to perfectly fit over the custom steel frame, the team added the finishing touch: brand-new, speed-rated racing wheels sourced from a local golf cart supply store.Cutting the plastic wheel wells to perfectly tuck the new rubber gave the truck an aggressive, lowered stance. "This thing looks absolutely insane, dare I say maybe even a little bit cooler than the Corvette," the host marveled at the final reveal.While the engine is mounted and the body is secured, the team is still hunting for the perfect rear axle to handle the Hayabusa's explosive power delivery. Standard golf cart axles simply won't survive 200 horsepower, meaning the BUM crew is likely going to have to chop down a real automotive rear end to finish the ultimate childhood dream car.
