These may be stupid questions to you guys but i'm new to this. I just bought my son a Honda ATC 90???. All the stickers say it's a 90 and the guy I bought it from says it is also. I went to a motorcycle junk yard t get handle bars (orig. were bent bad) and the guy there told me it was a 110 ATV. How do you trace the frame, engine and whatever else to verify its make. It is a 90/110? with a 3 speed auto trans.,
Low & hi range.

 

The engine size is cast onto the cylinders. 3wheelerworld.com Specfications page has more information.
I think the 90's all had fiberglass fenders. They also originally came with one piece tire/hubs. What kind do You have? Post a pic!! Welcome to 3-wheel fever!

 

Thanks Rexkarz,

I'm on my way to work now but will post pics tonight, It has the fiberglass rear fenders w/ atc 90 stickers on them but the guy told me it could have been changed. It has a 4 speed tranny with hi - low range & the engine is a 110 cc. I guess at this point I was wondering it it was a 90 that had a 110 engine & tranny put on it........ or a 110 with a 90 rear fenders..... pics later today. Either way it don't matter, it runs good and I got it for $300 & my son loves it.
