, it was officially released in 1968 as the CL450K1 "Scrambler" in silver, candy red and candy blue colors (only the tank and air filter covers were painted). This year also saw the addition of a 5-speed gearbox, an upgrade from the older 4-speed.

The CL450 remained much the same through 1974, though diverged further from its sister bike as time went on. While the CB450 went to a front disc brake in 1970, Honda decided to keep the CL450 with its two drum brakes. Disc brakes were fairly new technology on motorcycles, and unproven in off-road riding.

Honda's horsepower rating was 43 hp@9650 RPM off the crank, nearly 100 hp per liter.
Top speed could be seen as high as 96 MPH in stock trim with a well tuned carburetor. If highway speeds are more desirable, the CB450's gearing can be used to offer more relaxed cruising at higher velocities.
