A motorcycle with one driven wheel and 46-inch tires has no business looking comfortable in a sand dune. The Monster Chopper did anyway.Grind Hard Plumbing Co.'s video takes the KTM 1190-based machine to Sand Hollow State Park in Hurricane, Utah, for its first proper sand test. The bike climbed dunes, crossed deep sand, jumped rough terrain, and spent time alongside Robby Layton's tracked limousine during Matt's Off-Road Games. The video has since accumulated over 2,900,000 views and 36,000 likes, which suggests the internet remains fond of vehicles that look like they escaped from a desert warlord.The Monster Chopper Is Rear-Drive, Not MagicIts drivetrain routes power to the giant rear tire via a chain, a bespoke jackshaft, and reduction gears. Previous build videos show that only one wheel receives power, while the front remains unpowered – a striking dune feat without all-wheel drive.AdvertisementAdvertisementThe official video calls it a KTM 1190 machine with 46-inch tires. Earlier coverage used 1,250 cc and 160-horsepower figures, while New Atlas attributed 150 hp and roughly 100 lb-ft, or 136 Nm, to the KTM engine before the custom reduction system. According to Grind Hard's estimate, the tire receives roughly 3,000 lb-ft of torque, equivalent to 4,067 Nm, through the gearing.That drivetrain exists because the tires are absurdly large. First publicly shown in November 2023, the machine used 46-inch Mickey Thompson tires, Toyota hubs, a fabricated frame, custom swingarms and brakes, revised steering, chain drive, and a jackshaft. By January 2024, the project still needed steering refinement and brake work.During prior testing, the tires were set to 5 psi, while New Atlas listed the machine's mass at 814 pounds (369 kilograms). Ethan Schlussler admitted the speed compromise in late 2023: "I need a gear reduction so I'm going to go down and go for something like 25% so that we still have a top speed of 60-70mph," he said. RideApart later reported that the motorcycle lost stability once its speed climbed past 55 mph.Sand Hollow Turned Into a Mechanical Stress TestThe dunes run was not a sparkling laboratory demonstration. While traversing the washboard surface, the motorcycle threw its rear chain, and the team restored it using tools, a grinder, pliers, and replacement master links. The oversized chain also proved difficult to service because the available replacement link was the wrong size.AdvertisementAdvertisementThat failure did not stop the chopper from attacking the steepest sand. It pulled away from a dead stop on a dune, crossed deeper sections alongside Layton's tracked limo, and remained composed where much larger vehicles were struggling. The sand-running video features Dave Chappelle from The Dirt Head Shed alongside Trail Mater's Rory, Robby Layton, Ethan Schlussler, and Edwin Olding.The trip also included a 20,000-watt drift quad and a 750 Twin Barbie Dream Camper, although the camper later began smoking and was removed from the dune plans. The electric quad survived a full battery test farther from home than it had previously traveled, adding an unlikely supporting act to the chopper's main event.Sand Hollow's off-road area covers 16,000 acres at 3351 Sand Hollow Road. Matt's Off-Road Games currently lists its next event for March 18–20, 2027, with adult three-day passes at $124.99, youth passes for ages 13–17 at $69.99, and a $300 VIP option limited to 100 tickets.The Monster Chopper's journey ran from fabrication to its first drive on April 19, 2024, a hill-climb video on May 10, a Sturgis appearance on August 16, and finally the dunes. Apple TV and Tubi now package the installment as a 2026 episode lasting 43 or 44 minutes, but the original sand video remains the March 28, 2025 release. It is not a practical machihne, and it is not a sensible motorcycle. It is a heavily engineered answer to a question nobody needed to ask, which is exactly why it works.
