  • 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 agree. And the thing is, they're extremely tough when working properly. they can handle and tow most any weight at or below 1200 pounds (must have VERY little tounge weight though and the trike has to be in low range) and they could take huge beatings out on the trails. Sucks for the rider thoug, no suspension

      i love mine, been getting a real pounding for 26 years and still runs great, i have only had to replace the piston and rings, only till now it is starting to wear out. but simple rebuild to the engine will be a fun job worth every penny

      thanks for reassuring me guys, but now that i read that they do not have any suspention that makes me happy because i was really only worried about bottoming out the suspention and now that i know that is not possible i am not worried. now step two is getting it up and running and then camo paint

      My 1980 110 is running as good as it did from the factory and has never been rebuilt. Would recommend these things to anybody, tough machines is right! I have had mine going 45mph in high on a slight down hill, scary stuff with those floatation tires though.

      Can anyone give me some advice on getting my son 110 Honda not to run like its a 50 cc, it has no power.

      Laurie, you might want to make a thread on the forum with some information about the 110 so we can help diagnose it for you. I'd wager that the engine just probably needs an overhaul as a start, but ya never know, could be something else thats simple?

      Make sure the valves are adjusted properly. The last ATC110 I bought, doubled its compression after I adjusted the valves. Drives really well now!!

      I run nothing but Rotella Triple T 15w40 in my bike and atv engines with internal wet clutches because it's cheap and has a higher zinc content than all the other conventional motor oils being produced now... Most conventional and synthetic automotive grade oils contain friction modifying additives which will cause clutch slippage and excessive wear on them. Found that out the hard way! Why spend close to 10 bucks a quart for synthetic or the Honda stuff when this is just as good! I have researched many articles on this topic and made the realization that it saves money (and clutches!) and if it's good enough for whole fleets of 18-wheelers to last for literally millions of miles then it's good enough for me!
