500+ BHP BEAST BOSS HOSS POWERED BY A CHEVROLET HEART

Boss Hoss Cycles is an American motorcycle manufacture

In 1996, the Chevrolet ZZ4, a 350 cu in (5,700 cc) crate motor, was the standard issue engine in the bikes. The standard block is primarily made of cast iron while the heads are aluminum. A factory option for the bike also includes a GM "hot cam" which replaces the camshaft, pushrods, rocker arms, and springs in the heads. In 2000, Boss Hoss added the "Stud Hoss" to their line-up which was a 502 cu in (8,230 cc) Chevrolet big block. The "Stud Hoss" 502 was removed from the Boss Hoss line-up in 2008.

However, many still prefer a car tire. The only tire that has been certified to be used on a Boss Hoss is the Avon 230.

The first Boss Hosses offered included a one-speed manual transmission with a standard motorcycle hand clutch assisted by a Datsun B210 brake vacuum booster. The bikes used a standard ten-spline 12-inch (300 mm) disc clutch plate hooked to a Curtis spiral bevel gear box with a Chevrolet input shaft and a ​1 ³⁄₈-inch output shaft that had an attached sprocket. The first bikes were chain driven but changed to 1.5-inch-wide (38 mm) Dayton belts in the early 1990s. The ratio of the gear box used was 1.53:1. In 1999, a one-speed semi-automatic transmission was available for the motorcycles that utilized a torque converter and a pump with a set of clutch plates and steels basically added to the previous design gearbox, which worked very well. In 2001, a two-speed semi-automatic transmission with overdrive became standard with a heel-toe shifter and a reverse gear. Boss Hoss trikes have always offered a three-speed semi-automatic transmission with a real reverse gear.
