Honda CT90

The Honda CT90 was a small step-through motorcycle that Honda manufactured from 1966 to 1979, offered in two models, Trail or X, which differed mainly in gear ratios and tyre style. It was preceded by the CT200 Trail 90 of 1964 to 1966, which had a similar design, and before that by dealer-level modifications of the 49 cc Super Cub, the CA100T Trail 50 and the C105T Trail 55. The CT200 had an 87 cc iron-head pushrod OHV engine instead of the CT90's 89 cc aluminium-head OHC engine, and the change in model number reflected a new Honda policy that model numbers would indicate the engine size class. The CT200 and the 1966 CT90 had a dual rear sprocket for a lower gear range, replaced from August 1967 by a two-range sub-transmission set with a small lever.
