THERE'S OTHIN- ABOUTIl: A motor cycle is more than j ust ba sic

t ransportation. In t he case of t he 1983 Nigh thaw k" 450, much more.

Sophist icated and daring in it s approach to styling , the Nigh thawk 450 t akes on bikes outside of it s class. Its clean, int egr ated flow­t hrough lines, 57.1 inch wheelbase and agile steer ing geo metry give it a presence and feel normally associated wit h a larger mot orcycle.

But indi vidual styling isn 't the only t hing that sets t he Nighthawk apart from ot her mot orcycles. Few st reet mot orcycles achieve as fine a balance between power and size as t he Night hawk, a balance proven and engi nee re d by Hond a technology.

The Nig hthawk's power comes from a SOHe, 447cc, vertica l tw in. This engine, smoot hed by cha in-dri ven, du al counte r­balancers, feat ures Honda's offse t , three-valve, Pen troof'combustion chambe r; 'Iwo smaller valves increase t he overall

flame propagat ion, w hile the Pen troof combus t ion chambe r eliminates pockets t hat can cause uneven bur ning of t he air-fuel mi xtu re. Working together; t hese important design eleme nts create clean er and more efficient burning of the air-fuel mix ture. And that means more powe r. 1\\'0 :30 mm constant ve locity ca rburetors let e ngine demand se t t he correct air / fuel mixture and provide cr isp t hrottle response. A Tri-Pulse r'tsolid st ate CD igni tion deli vers t he spar k this high­performan ce twin requires. And t he Power Cha mber" e xhaust system, located beneath the engi ne to im prove mass ce nt ralizat ion, increases mid-ran ge power

A fi ve-speed plus over dr ive six th transmission t r anslates t he engine's power into goo d acceler ation. Over dr ive allows the Nighthawk to cr uise easily with the engine t urning 100\'er revs for fuel e fficiency. A dura­ble #5:30 sea led O-r ing drive cha in delivers t hat power to t he real' wheel e ffic iently.
