1967 - Trail 90 'K0


1967
 
The 1967 Honda CT90 'K0, continued the use of model designations that started with the letter 'K", followed by a number. The 'K0 was manufactured in 1966, 1967 and 1968. And even though there were some major changes, the model designation of 'K0 remained in all those years. The early version of the 1967, CT90 'K0's was essentially the same as the 1966, CT90 'K0. However, about half way through 1967, starting with Serial on VIN number CT90-122551, a major improvement to the CT90 'K0 was the addition of the Dual Range Sub Transmission. This was an easier way to get a low range gearing for climbing hills. Instead of having to move the large rear overlay sprocket to bolt onto the regular rear drive chain sprocket, and adding a drive chain extra segment, the rider simply needed to come to a stop, get into neutral gear, flip a mechanical lever, then take off again.
