  The Big One, or CB1000, was a naked tourer style bike first built by Honda in 1992. Production ceased in 1997, although bikes were sold until 1999. The engine for the CB1000 was taken from the CBR1000, losing 15 horsepower in the refitting process. The bike was popular in Europe and Japan, with a special CB1000T edition coming out specifically for the Japanese domestic market. However, the Big One didn't sell well in the U.S. for the two years it was offered, and was removed from the American market in 1995.

Engine

• The bike has 998 cubic centimeters of engine displacement (i.e. the volume inside the cylinders that is swept by the pistons). It has a four-stroke engine, which means that the pistons take four strokes to complete an engine cycle.

  The bike has four cylinders inline with four valves per cylinder, using a double overhead cam configuration, and is liquid-cooled. The bore and stroke of the engine is 3.0 inches by 2.1 inches.

Transmission and Chassis

• The bike uses a chain as a final drive system to transfer engine power to the back wheel and has five manual gears.

  The CB1000 has dual disc brakes on the front wheel of 12.2 inches diameter with four piston calipers and a single disc brake on the rear wheel of 10.9 inches with one piston caliper. (A disc brake uses a pad pressing on a fixed metal disc to slow the wheel.)

Dimensions

• The bike weighs 518 pounds without any oil or fuel and has a fuel capacity of 5.8 gallons. The bike has a wheelbase of 60.6 inches and a seat at a height of 30.3 inches for the 1993 version and a height of 31.9 inches for the final 1999 version. The front tire is 120/70-18 size and the rear tire is 170/60-18 size. The tire designations mean that the front tire, for example, has a width of 120 mm, a profile (cross-section) of 70mm and a rim diameter of 18 inches.

Performance

• The 1993 Big One has 95.6 horsepower at 8,500 revolutions per minute (rpm) and produces a torque (turning force) of 64 foot-pounds at 6,000 rpm. The latest version produces 98 horsepower, a small improvement of 1.5 hp at 8,500 rpm on the early versions. The power to weight ratio is 0.186 hp/lb for the 1003 bike and 0.189 hp/lb for the last version of the bike.

  The 1999 bike can get from zero to 60 miles per hour in 4.4 seconds.
