Intro[edit | edit source]

When Honda introduced the CB450, they served notice on the world's motorcycling industry that they could build large capacity machines that had superior performance and technical innovations than any European bike. Known in Europe as the "Black Bomber", this machine opened the door for the rest of the Japanese manufacturers to enter the big bike market. It was the bike that was supposed to put Honda on the big bike map with the likes of the British manufacturers, but in reality it didn't. That would have to wait 4 more years for the introduction of the Honda CB750K.[1] It retained much of the looks of the earlier CB77 Super Hawk, but internally much was changed.

Engine[edit | edit source]

The engine was a air cooled twin, four-stroke. A 75.0mm bore x 50.6mm stroke result in a displacement of just 447.0 cubic centimeters. Fuel was supplied via a overhead cams (ohc).

Drive[edit | edit source]

The bike has a 4-speed transmission. Power was moderated via the wet plate.

Chassis[edit | edit source]

It came with a 100/90-18 front tire and a 110/90-18 rear tire. Stopping was achieved via dual disc in the front and a expanding brake in the rear. The front suspension was a Telescopic fork while the rear was equipped with a Swing arm. The CB450S was fitted with a 4.76 Gallon (18.00 Liters) fuel tank. The bike weighed just 388.01 pounds (176.0 Kg).

Issues[edit | edit source]

Early models featured a clunky transmission and finnicky carburetion.

The CB450K0 was sold from 1965 to 1968 in one basic color scheme- Black with Silver.In the USA,there were limited numbers of Red with Silver as well,but few exist today.In Great Britain,where sales were lukewarm,the model was revamped in Red with Silver,and also the very rare combination of Blue with Silver,in order to move the inventory. The gas tank, upper forks, and headlight shell were the primary color. The side covers and fenders were silver. The gas tank had chrome panels with black rubber knee pads. The instruments were in the headlight housing. The engine was a 444cc DOHC parallel twin with dual CV carburetors. The transmission was a 4-speed. The serial number began CB450-1000001.

CB450D[edit | edit source]

  Honda CB450D

The CB450D (also designated CL450K0) was sold in 1967. The 'D' model was formed out of an attempt to move CB450K0 'Black Bombers' that were not selling, sitting on the US dealer showroom floors. Honda produced a dealer installed 'kit' that transformed the standard CB450K0 into the 'D' model. Honda shipped its US dealers a package that included a newly designed tear drop tank (that became the predecessor to the CB450K1 tank), side covers, fenders, tailight, handlebars, special upsewpt exhaust pipes, and a new style seat to complete the transformation of the old 'hump tanked' Black Bomber , which was at the time referred to us the 'ugly duckling', this the reason for the new body work. It came in three color schemes: silver, orange and blue tank and side covers. The upper forks and headlight shell were black. The fenders were chrome. The two chrome exhaust pipes were upswept one on each side. The "450" side cover decal was on a checkerboard stripe. The engine was a 444cc DOHC parallel twin with dual CV carburetors. The transmission was a 4-speed. The serial number began CB450-1000001.

CB450K1[edit | edit source]

The CB450K1 was sold from 1968 to 1969 and came in one of three colors: Black, Candy Red or Candy Blue "Bankers Blue". The gas tank and side covers matched, while the headlight shell and fork covers were black (unlike all other models in following years). This was perceived by some to copy the look of the BSA of the same period, whose fork covers were typiccaly black (as was Triumphs). The K1 was considered the only real attempt to copy the British look of BSA, Matchless, AJS and other Brit brands (from the newly designed teardrop shaped tank with chrome side panels and knee pads, right down to the white piping on the seat and the new chrome fenders..a first for Honda, as all previous years and models had painted fenders). The seat top surface was a unique heavy 'alligator'grain, with smooth grain side panels, seperated by small white edge piping. The tail light lens had a rounded rectangular shape (last year). The original gas tank badge "HONDA" was the cast plastic type as used on the KO (also the last year for the round emblem). The simple '450' side cover emblems were thin stainless sheet metal (all later models used plastic) There was an independent speedometer, tachometer, and headlight unit (first year). The engine was a 444cc DOHC parallel twin with an updated version of the crankshaft layout and crankcases,and revised dual CV carburetors. The transmission was upgraded to a 5-speed. The serial number began CB450-3000001. The European version carried the same valanced fenders as seen on the K0 four speed,with the exception of their being chrome plated,and the speedometer read in KPH rather than MPH. The European model also used rubber fork boots 'gators' as the lower fork covers (as used on the US CL450K1 models) instead of the steel sleeve covers. Other than these few variations, the US model and European model were virtually the same.
