1966 - Trail 90 'K0

For 1966 Honda had some CT200's still being manufactured, with essentially no change in the common characteristics from 1964 and 1965 models. The Honda parts listing always mentions the CT200 as a 1964 and does not mention a 1965 or a 1966. The starting Serial or VIN Number for the CT200's in the year of 1966 is unknown. The year designation found on state titles or registrations for the CT200 usually refers to the year in which it was first sold. Production and dealer ordering (often controlled by American Honda) sometimes left CT200's on dealer showroom floors into the following years. We have seen several cases of CT200's with titles stating late into the 1960's or even the early 1970's, well after production stopped for the CT200.
Sometime in 1966 Honda started making the CT90 'K0, where they started to use model designations that started with the letter 'K", followed by a number. This is the birth of the 'K0. 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 1966, CT90 'K0's major improvement was the addition of the 89 cc, overhead camshaft engine. This was a more efficient and powerful engine, using all the modern technology of 1966.
