Consider the question. Making amends for years of underperforming V-twins, Honda set out to produce a cruiser with the biggest CID ever and so designed a big bike with a muscular looking body that was long and low to the ground, featuring significant rake and trail. Honda claimed that the 1800 put out 159 N m (117 lbf ft) of torque at only 3000 rpm and 75 kW (101 hp) at 5000 rpm, making the VTX1800 one of the most powerful production V-twin motorcycles of its time. (See infobox for measured horsepower and torque values.)
