Motorcycle weight is expressed in three ways: gross vehicle weight rating (GVWR), dry weight and wet weight. GVWR is the maximum total weight of the motorcycle including all consumables, the rider, any passenger, and any cargo.
However, at lower speeds a rider may experience excessive weight on the arms and wrists, causing fatigue. Muscle bike is a nickname for a motorcycle type, derived from a sport bike design, that puts a disproportionately high priority on engine power. [6] [27] [28] [29]

[ 4 ] Power output is tested at 178 hp (133 kW) [ 5 ] and peak torque is 75.4 ft⋅lbf (102.2 N⋅m) both at the rear wheel. [ 1 ]
A Suzuki GSX-R1000 at a drag strip – a 2006 model once recorded a 0 to 60 mph time of 2.35 seconds. This is a list of street legal production motorcycles ranked by acceleration from a standing start, limited to 0 to 60 mph times of under 3.5 seconds, and 1 ⁄ 4-mile times of under 12 seconds.

For example, a motorcycle with a 12 inch wide rear tire will have t = 6 inches. If the combined bike and rider center of mass is at a height of 26 inches, then a 25° lean must be increased by 7.28°: a nearly 30% increase. If the tires are only 6 inches wide, then the lean angle increase is only 3.16°, just under half.
