Engine and Transmission parts for Honda CT90 / Trail 90 motorcycles

The Honda CT90 / Trail 90 engine was produced from 1966 to 1979 and features an 89.5cc four-stroke, single-cylinder overhead cam engine paired with a 4-speed semi-automatic transmission. Early K0 - K5 models use a reverse shift pattern is N-1-2-3-4 when pressing down (forward like a rear brake lever) on the shift lever. Later K6 - 1979 models operate in reverse, still the N-1-2-3-4 pattern, but the shift lever is moved up, like a typical up shift on a clutch motorcycle. Unlike larger Honda models, the CT90 uses a centrifugal clutch, allowing for smooth shifting without a clutch lever. One of its most notable features is the dual-range sub-transmission, which provides high and low gearing options for tackling both street and off-road conditions. Engine and transmission parts for the Honda CT90 / Trail 90 include Allen bolt kits, drive chains, gasket kits, cam chains, clutches, and shaft seals.
