  • ATC110 Technical Data

    The US90 and ATC90 proved to be a pivote point for Honda's line up of all terrain cycles. With other manufacturers trying to get a slice of the pie the obvious choice to remain competitive was to increase performance and features. The Honda ATC110 does just that by taking a proven platform, the ATC90 and bumping the displacement up to 105cc.

    Like the previous model the ATC110 went through several generational changes slowly evolving the model into a stylish modern looking machine. Several seat and tank refinements smoothed the styling of the 110 while several updates to the braking system, intake track, air box and lighting developed the already stout ATC into an even more comfortable and dependable machine.

    The ATC110 also enjoys a place with the ATC70 as one of the few machines in the Honda catalog to be offered in a dark blue color contrasting the models traditional red. (more info on the blue variants to be added at a later time)

      I got a shiny new 1985 Honda ATC110 when I was 12yrs old. The only thing I put into it was gas, I never changed the oil- not once. Sold it in 1995 to a old farmer at my mom's lawn sale, and it would start 1st-2nd pull everytime. On a different note, when I was a little older 15-16yrs old. I had a friend who had a Kawasaki 110 that was beat to death and we decided to kill by draining the oil and bunging the throttle WO out in the woods, I left 2hrs later with the thing still pinned screaming in the woods. I wonder what the hell city people do as kids?

      I was measuring my rim bolt size and it is 4/130. Is that right? I’m new to this site so I hope I don’t bug you all too much with questions.
