7. NT650 Hawk GT
One of the greatest sleepers of all time, the Hawk GT was often overlooked by consumers desiring something with a sportier appeal such as a CBR600F. Even with a twin-spar aluminum frame and only the second Honda to wear the single-sided “Pro-Arm,” (the first being the RC30), and a wet weight of 414 pounds, the Hawk failed to attract many buyers. It wasn’t until Honda dropped the price and models, new and used, started circulating among riders and racers that it reached its potential as a cult classic. Brought stateside from 1988 to 1991, the 647cc, liquid-cooled Twin wasn’t the fastest engine out there, but it, essentially, was the Ducati Monster of its time.
