Boss Hoss BHC-3 502 2007 — Specifications

The figures in the Boss Hoss BHC-3 502’s technical specifications look like a typo. Eight thousand two hundred cubic centimeters, five hundred two horsepower, five hundred sixty-seven Newton-meters. These figures have nothing to do with the world of motorcycles; they belong to heavy machinery or naval propulsion. Yet, this thing rolls on two wheels and has a handlebar. The basic idea is extremely simple: to graft the small 502 cubic inch Chevrolet V8 engine, a classic of American hot-rods, onto an oversized custom chassis. The result defies all logic, all categories, and probably all European legislation regarding driver's licenses.

The engine is the machine’s sole reason for being. This Quadrajet carburetor V8, with 850 cfm, liquid-cooled, runs with the nonchalance of a tractor. At 4200 rpm, it delivers its monstrous torque of 567 Nm, a value that would make a Bugatti Veyron of the time cry. The power of 502 hp arrives at 5200 rpm, but you can feel that the curve must resemble an Idaho plateau. The final transmission by belt and the three-speed automatic gearbox (or four depending on the versions) transform this madness into a usable machine. We are talking about a motorcycle that weighs nearly 600 kilos dry, with a wheelbase of two meters and eighty. The Harley-Davidson Electra Glide looks like a scooter by comparison.

The chassis and suspension exist to contain the mass, not to make it dance. The 63 mm inverted fork and the two rear shock absorbers have a titanic job. The brakes, a double disc at the front and a single at the rear, seem derisory compared to the kinetic energy of a half-ton launched. The seat height of 724 mm is ridiculously low for a machine of this size, as if the manufacturer wanted at all costs for the rider to be able to put their feet on the ground. With a 32-liter tank, you can cover an honorable distance between gas stations, provided you don't overly stress the right wrist.

Riding a Boss Hoss BHC-3 502 is experiencing a form of gentle violence. It doesn't vibrate, it trembles. It doesn't accelerate, it sucks in the horizon. It doesn't brake, it slows down reluctantly. It is the anti-motorcycle par excellence, a declaration of independence from any notion of maneuverability, agility, or finesse. It has no competitors, except perhaps a dragster or a motorboat. Its audience is minuscule and perfectly defined: eccentric collectors, hot-rod culture enthusiasts, and those for whom the notion of "too much" simply doesn't exist. It learns nothing about motorcycles, but it says a lot about pure American audacity, or madness.
