The Hawk GT is one of the first modern naked bikes along with the Yamaha SRX, which were both released several years before the Ducati Monster and eventually the Suzuki SV650. The Hawk GT is often described as a cult bike.
North American model
The US model NT650, Hawk GT 647, RC31 was introduced in 1988 and produced through 1991. It has an aluminium box frame with the separate rear frame bolted on, and a chain-drive, single-sided swingarm.Priced above other entry-level models and only slightly below many 600 cc sport bikes, the Hawk GT did not sell well in American markets.
There are only very minor changes between the 1988 model year and the 1989-1991 model years. In 1989, the front suspension damper rods were changed to have only two holes. The front brake calipers were also changed to have screw-on covers over the mounting pins. In 1991, the oil lines were run internally through the engine, rather than externally. The Canadian model was identical to the US model except for the colors. In the US, the 1988 model was offered in Tempest Gray and Tanzanite Blue. In subsequent years, Bright Red only was offered in the US.
The 1988 model had a wet weight of. The 650 cc engine had a claimed output of @ 5000 rpm.
European model
A cousin to the Hawk GT, the NTV 600 "Revere" was available in Europe from 1988 to 1992. It had an integrated steel frame, larger fuel tank, a lower and stubbier silencer, shaft drive, single-sided alloy swinging arm at rear with adjustable monoshock and a centre stand. It was launched as a "gentleman's" motorcycle but was seen as expensive for what was on offer.The 600 Revere was replaced in 1993 by the bored-out NTV650, with a cheaper specification, and continued with the "stubby" silencer until 1995 and later models got a full-length silencer to comply with updated noise regulations. The price was reduced compared to the Revere, and this later model sold better.
The NTV650 was replaced in 1998 by the Spanish built NT650V Deauville, a much heavier fully-faired model with integral small panniers and a steel double-sided swinging arm.
