Comments

Without doubt the new CB650´s most impressive features are its valve-lash adjustment and its low-maintenance design. Honda engineers seemto have removed the last tedious, time-consuming ritual from motorcycling´s Saturday afternoon
Here is a machine that fulfills the 650 promise: it feels small, smaller than a 750, yet runs with 750s without even breathing hard. Its smoothness and comfort invite long rides. The rear suspension´s springing and damping rates do need tuning to provide a more supple ride; and for sporting riders, Honda´s engineering department should attend to the drive line´s irksome lash and shaft reaction. Having a motorcycle that needs barely more maintenance than a safetypin is a bargain only if its owner genuinely enjoys the way the motorcycle works. Diehards may complain sourly about ´appliance-like´ character, but few riders will quarrel with the way this motorcycle functions. For about six or seven years, first one manufacturer and then another has proclaimed that its 650s perform like 750s; certainly there´s been much sound to this proclamation but little real 750 fury. Now the 650 Nighthawk delivers.
Everyone who has ridden the 650 Nighthawk has come back impressed. This 650 is the new measuring standard of the 40-inch class. And the standard has just been raised. A lot. |
