Created For Snow Traction, The Monster Chopper Combines Giant Backhoe Wheels, Powerful Engine, And Hydraulic Steering In A Unique Engineering

The Monster Chopper integrates a select group of motorcycles that impress with their size and boldness. It’s not for road or track performance, nor for its striking appearance. The highlight comes from the giant wheels, which give the model a unique and imposing character.

Created by Grind Hard Plumbing Co., the bike was designed for snow traction. The 46-inch tires, equivalent to 1.17 meters in height, already deliver the scale of the project.

To move this mammoth on wheels, the group — known on YouTube for creating unusual vehicles — installed a KTM engine. And, to make control possible, they resorted to hydraulic steering.

Engineering On A Large Scale

The Monster Chopper is not the first bold project from Grind Hard Plumbing Co. On their social media, you can find everything from a goalie car with a Yamaha R1 engine to sports bikes transformed into snow motorcycles.

The new creation, however, stands out for combining backhoe wheels with a high-performance engine.

The chosen one was the powertrain from a KTM 1290 Super Adventure, with 160 hp at 6,750 rpm and a maximum torque of 140 Nm.

The sound of the engine combines with the metallic noise of the tire pins, creating a unique experience.

The hand-built frame, without fairings, required many hours of work and autogenous welding. In the end, the bike can be described as a robust chassis mounted on colossal tires.

Challenge To Maneuver

The most important thing is that, besides brute strength, the Monster Chopper needed control. For that, Grind Hard Plumbing Co. adapted a hydraulic steering system similar to the one used in the Bimota Tesi.

The mechanism central to the front wheel hub, although simpler, guarantees efficient operation.

The suspension received parts from the frame of a Honda CBR900RR, reinforcing the mixture of components from different models to achieve the desired result.

However, riding the bike is not a simple task. As shown in the released video, the rider keeps their feet close to the ground to balance the weight and height of the machine.

According to the creators, adjustments will still be made to improve drivability and allow for longer distances than the few meters recorded in the footage.

Thus, the Monster Chopper establishes itself as another example of the bold and creative work of the group, which continues to explore the limits of engineering on two wheels.
