There seems to be more interest in restoring the old ATCs. I have been a big fan of ATCs since the beginning and never stopped riding them to this day. I have noticed more and more posts regarding identifying these older ATC models so I compiled the numbers that apply to the ATC70 and posted them here. These models, along with the ATC90, are the hardest to identify to those unfamiliar to them because Honda never adopted the USDOT alpha system for identification until after the 1979 model year and even then....it took another year to get it right.

The ATC70 uses a 72cc OHC single with a 3 speed [73-81] or 4 speed [82-85] auto clutch transmission.

Hope this info helps you guys get to know your ATC70 a little better.

By the way, I plan on doing a topic like this regarding ID numbers for ALL the Honda ATC models. I'll try to get one up every 2 or 3 days if possible.

If you guys object to this because it might clutter up the ATC forum, let me know. I will understand and space them out further apart.....Like one a week??

Just let me know.
