Road Test Cycle Magazine of 1986
Witness the American Gothic of motorcycles: Many of the values reflected in Grant Wood's portrait of the thin-lipped farming couple—hard-working, modest, capable, and utterly without glamour—apply directly to Honda's workhorse Nighthawk.
In 1977, when Honda brought out the 450's parent bike, the CB400 Hawk, it was a revolutionary machine. The original Hawk showcased a number of innovations—a stressed-member frame, three-valve cylinder heads, dual chain-driven counterbalancers, composite wheels using tubeless tires. Within months of the Hawk's introduction came even greater technological accomplishments from Honda: the amazing six-cylinder/24-valve CBX, the radical liquid-cooled, shaft-driven CX500, and a new generation of inline fours highlighted by the twin-cam CB750. The Hawk's modest achievements got lost in an avalanche of new technology.
Three of those machines are long since gone, but the Hawk, with relatively minor updates, runs on far into the 1980s. Its modest price has always tagged it as an economy bike, and its unassuming styling has kept the Nighthawk a 'standard.' With few inexpensive motorcycles on the market today and even fewer standards, the enduring CB becomes all the more noteworthy.
The Nighthawk's engine is built around a surprisingly oversquare 70.5 by 50.6mm, 447cc engine. The bike's dual counterbalancers—a technology which was in its infancy when this engine was first built—allow the CB to use a light, single-downtube frame and mount the engine solidly as a stressed member. A six-speed gearbox (introduced in 1980) lets the bike perform yeoman duty as everything from mini-tourer to novice peg scratcher. Years ago, the original's assembled ComStar wheels became the cast pieces we see today, as much for cosmetic as functional reasons.
In 1982 Honda gave the bike its biggest change, a bore job bumping the engine to present spec, along with stronger rod bolts and crank bearings to cope with the added power and heavier pistons. The integrated, crankcase-mount oil cooler remained, but Honda upgraded the twin's suspension and brakes to current specs.

From our point of view, the Nighthawk's greatest attribute is something that hasn't changed: its seating position and chassis setup. In Honda's CMX450 Rebel we see a machine with fundamentally the same engine as the CB-SC (the Rebel uses a different crankcase for cosmetic reasons, has carburetors two millimeters smaller, and different transmission and final-drive ratios), yet a substantially different chassis layout and ergonomics, clearly in the name of style. With the 650 Savage, a completely new bike selling for the same price as the CB, Suzuki put its R&D money into styling as well, utilizing a new engine neither as sophisticated nor as flexible as the Nighthawk's 'old' powerplant. Kawasaki's 454 LTD got a hot twin-cam water-cooled engine, but with that comes a $300 price bump along with cruiser ergonomics.
Not that the Nighthawk suffers in performance: it zips through the quarter mile in 14.55 seconds, nearly half a second faster than the 650 Savage. Surprisingly, the Rebel does even better by 0.07 second and 4.7 miles per hour, most likely due to its gearing. Still, of the two Hondas, we choose the Nighthawk.
Why? No spec chart can indicate the Nighthawk's genuine advantage. The CB450 lets its rider sit upright, providing enough room for even six-footers to stretch out and move around. The Rebel, 454, and Savage all position their riders in a feet-up, hands-high riding position, fine for the boulevard but fatiguing during any forays away from the stoplights. Conversely, the Nighthawk's medium-rise bar and rearward-set pegs lean its rider slightly into the wind, and that position, along with the bike's wide, generously padded seat and freeway-compliant suspension, allows the CB-SC rider to comfortably drain the bike's fuel tank—about 160 miles—without ever requiring a rest stop. For passenger duty as well, the Nighthawk bests any of the three cruiser bikes.
