The Honda NT650, also known as the Hawk GT, RC31, and Bros, was a naked machine manufactured from 1988 to 1992. Toshiaki Kishi designed the NT650, the second Honda motorcycle with a Pro-Arm suspension after the RC30 VFR750R.
The RC designation was used for bikes up to 750cc displacement, but the Honda Pacific Coast PC800 model had it higher than 750cc and an RC34 designation.
The Honda NT650 and the Yamaha SRX were two of the most modern naked machines launched several years before the Ducati Monster and Suzuki SV650 models. Also, the NT650 was often called a cult motorcycle.
In 1991, the Japanese maker launched the Honda NT650 Bros, a naked machine that debuted in 1988 and continued production until 1992. The bike featured a two-up seat, cast aluminum wheels, a round headlight, and a side stand.
For suspension, the bike was handled by a 41 mm telescopic fork on the front end. At the same time, on the rear, it was driven by a preload and rebound adjustable Pro-Arm shock absorber, offering optimum suspension performance and handling.
As for the stopping power, the bike was fitted with one 316 mm disc with a dual-piston caliper on the front wheel and a 276 mm disc engaged by a single-piston caliper on the rear wheel, providing strong braking power.
The 1991 Honda NT650 Bros took its muscles from a 647cc liquid-cooled V-twin engine with two carburetors, delivering an output power of 56 hp at 7,800 rpm and 57 Nm (43 lb-ft) of torque at 6,000 rpm.
