1971 - Trail 90 'K3


1971
 
The 1971 Honda CT90 'K3, continued the use of model designations that started with the letter 'K", followed by a number. There were only a few changes from the previous year to the CT90 'K3 and no mid year changes in 1971. The Yellow color was changed to Summer Yellow. The exhaust was now a black body with a chrome heat shield.
 
The "States", via their Department of Motor Vehicles (DMV) or similar named agencies, control the regulation of equipment on vehicles and NOT the United States Federal Government (which could be a more "uniform" set of laws, used in all states). Thus, each state is allowed to set it's own laws regarding equipment on vehicles. Several states (California, Georgia, Kansas, Maine, Massachusetts, Nevada, New Hampshire, & Oregon) had already written laws requiring motorcycles to have turn signals as standard equipment by the end of 1973 (start of 1974). Several motorcycle manufacturers, including Honda, were preparing for this requirement and had in fact started installing turn signals on other models. The best evidence of this is the inclusion within the speedometer of an indicator light for turn signals and on some years the left handlebar switch to activate the turn signals. The 1971 'K3, had the extra light for indicating the activity of turn signals (often called "winkers" in documentation, and labeled with a "W" on the speedometer face). And, there are a few reports of 1971 'K3's having turn signals factory installed, but as of yet we don't have photo proof.
