The CT90 was another example of Honda paying attention to what American buyers wanted. Honda focused their attention on versatility, ease of use, and reliable engineering. The CT90/Trail 90 came years before the first 3-wheeler or ATC (All Terrain Cycle). These odd looking machines had a 4 speed transmission with super-low gearing and a simple, yet effective automatic clutch. Not only was the transmission fitted with a centrifugal clutch hub that would engage the crankshaft gear with the input shaft at a predetermined RPM, each movement of the shifter opened clutch plates like those used in a manual clutch. Brilliant – the bike would engage like an automatic in a car from stopped, but then gear changes were accomplished smoothly and without damage through the use of a manual clutch throw-out system activated by the very movement of the gear selector. The design is worth taking a look at, I was and still am impressed with the simple yet effective system.
