Honda Trail 90

Question:

How do I figure out if this is a CT2, CT3 OR CT? {John, CA, US, - 1971 Honda Trail 90}

Answer:

At first, I was not sure what you meant by is it a CT or CT2? The CT2 and CT3 are Yamaha designations from the 70's. Your question says you have a 1971 Honda Trail 90 so I started with our old microfiche deck and contacted a veteran of the Honda Hoot.

For you youngins out there, the Honda Hoot was kind of like Sturgis for Honda riders. The Gold Wing ruled the roost. As far as I know they no longer hold the official Hoot.


Here is a little background information. Back before the 17 digit VIN, a bike made in 1968 in Japan but sold in 1970 in the US was considered a 1970 and the serial number tags, put on in the US, reflected that.

During the late 1960s and though out the 1970s, many Honda bike model names ended with K# {K and a number} to indicate the model edition. The first edition was a K0, the next a K1, and so on. But it did not necessarily mean year 1, year 2.

For example the Trail 90 CT90K0 was sold from 1966 through 1968. Honda collectors have their own vernacular and may refer to different Trail 90's in shorthand. Saying the CT2 and meaning the CT90K2 model.



Check the serial number (VIN) of your Trail 90 against the chart below.



Honda Model Edition Code Year and
Serial Numbers
CT90K0 1966-1968
serial number began CT90-100001
CT90K1 1969
serial number began CT90-200001
CT90K2 1970
serial number began CT90-300001
CT90K3 1971
serial number began CT90-400001
CT90K4 1972 – 1973
serial number began CT90-1400001
CT90K5 1974
serial number began CT90-1500003
CT90K6 1975
serial number began CT90-1600003


The abbreviations changed in 1976 to include the year instead of a K#. For example the 1976 Trail 90 was CT90'76. In 1981 they changed to the 17 digit VIN we know & love. I hope this answers your question.
