1972

The 1972 Honda CT90 'K4, continued the use of model designations that started with the letter 'K", followed by a number. There were no mid year changes in 1972. This was the first year that there was only one color of the CT, it was Mars Orange. This is also the first year for the auxiliary gas tank mounted under the large rear cargo rack on the left side. The auxilary gas tank bracket also had a helmet lock, where a "D" ring of the helmet strap could be locked to the CT. This is the first year for the speedometer to have a trip odometer. The speedometer had the extra indicator light for turn signals (see 1971 'K3). And, there are a few reports of 1972 'K4's having turn signals factory installed, but as of yet we don't have photo proof.
