Interesting topic though....can't wait to see what all comes out.
Oh...another thought, wasn't 84 first year with a parking brake tang on the brake lever?

The all-terrain vehicle (ATV), also known as three and four-wheelers, was initially developed in Japan as a farm-to-town vehicle in isolated, mountainous areas. During spring thaws and rainy seasons steep mountainous roads were often impassable with conventional vehicles. The three-wheeled ATV proved to be a much better mode of travel and soon became a recreational vehicle, providing transportation to areas inaccessible by other motorized transport. And, it wasn't long before the Japanese manufacturers realized that the ATV could be sold to Americans.
When the ATV first appeared in the United States in the early 1970's, it was promoted and sold as a recreational vehicle designed to provide "thrills" for the rider. This is still its primary use today. Shortly, however, sportsmen found that the ATV was a useful machine to move through areas not accessible with pick-up trucks, four-wheel drives, or other motorized vehicles. The ATV became popular as a hunting vehicle and was used to reach remote areas and to transport game back out.
In this two-part chronicle, we discuss Honda's introduction, involvement, and innovation in the all-terrain vehicle industry.
--------------------------------------------------------------------------------
Three decades ago, the first ATV, Honda's US 90, had a single-minded purpose: off-road recreation. But as Honda's family of ATVs grew, so did their usefulness. Ironically, it was market strategy that at first drove ATV usage, but it was the owners who found and invented new and creative applications for ATVs, and helped shape their growth and design along the way.
What these hard-working owners found out was that the ATV offered a stunning versatility even Honda engineers never dreamed of. Less expensive to operate than a pickup or tractor, smaller and more maneuverable than either one, and possessed of a remarkably light footprint (with their low-pressure tires) that was easy on sensitive terrain, ATVs became vital tools in such widely divergent fields as farming, ranching, industry, all types of agriculture, police work-even as a crucial means of mobility for the disabled. In some cases, ATVs did jobs no other vehicle could, making the impossible possible.
The 1960s: Prototyping the ATC
Founder -- Soichiro Honda
If necessity was the mother of the first ATV, Honda engineer Osamu Takeuchi was its father. In 1967, American Honda asked Honda R&D Ltd. for a new product dealers could sell when motorcycle sales cooled off in the winter. Mr. Takeuchi was assigned to lead the project, along with a small group of engineers. This was clearly the group for the job, since Takeuchi and company had been working to develop other new recreational vehicles that never saw production. These projects gave Takeuchi the tools to develop Honda's first ATV, the US 90.
Forget the proverbial blank sheet of paper. Takeuchi started in the shop with a head full of ideas and an eclectic assortment of components. Two, three, four, five and even six-wheeled configurations were examined, but the three-wheel concept delivered the best combination for the machine's intended mission. It dealt with snow, mud and assorted slippery conditions a two-wheeler couldn't, while providing more maneuverability than other configurations.
1950's -- Soichiro Honda on the assembly line.
In the early stages, a Honda ST70 motorcycle gave up its 70cc four-stroke single-cylinder engine for the cause, along with assorted chassis parts. An extended rear axle carried cultivator wheels designed to handle rough terrain. Two driving wheels in the rear worked well. Cultivator tires didn't. The biggest challenge would be finding a tire capable of getting a grip on soft, changeable terrain such as snow, sand and mud. Two wheels, three wheels, four wheels or more? Motorcycle tires weren't an option.
The design process quickened when Takeuchi received an American invention called the "Amphi-Cat¨ that rolled on six 20-inch low-pressure, high-flotation balloon tires. The light bulb went on. Revamping his ST70-based prototype to accept the new low-pressure rolling stock, he went to work on his own tire design, ending up with a 22-inch design inflated to 2.2 psi. With the tire dilemma solved, the 70cc engine lacked the muscle necessary to push a full-sized rider through snow or mud. A 90cc engine running through a special dual-range four-speed gearbox added the requisite flexibility over varied terrain.
The next phase of development was optimizing the chassis to match the new engine and tires. Testing over rough roads, sand hills and slopes as steep as 35-degrees gradually established chassis dimensions effective for recreational riding as well as agricultural work. Laid out in the shape of an isosceles triangle with the footpegs located outside the triangle to optimize control, the ATC design was unique enough to let Takeuchi patent the arrangement.
Exhaustive testing brought other lessons to light as well. Using a thumb throttle instead of the typical motorcycle twist grip let riders shift their weight for optimal vehicle maneuverability while maintaining precise throttle control. A rear differential was considered, but discarded when a live axle performed better. Though suspension is an integral part of the modern ATV, Takeuchi's original balloon tires soaked up rough terrain best by themselves. Exerting less pressure on soft or sensitive terrain than the average human foot, those tires let the vehicle go places others couldn't, leaving little or no evidence of their passing--an advantage that looms large in hundreds of modern ATV applications.
The 1970s: The World's First ATC
The 1970 ATC 90
Officially introduced to America in 1970, the US 90 sent its 7 horsepower through a dual-range four-speed gearbox with automatic clutch, and sold for $595. It was renamed the ATC90 later that year as Honda trademarked the ATC name. Three models carried that Honda ATC monogram through the 1970s. The ATC70 gave younger riders a scaled-down version of the fat-tire experience. And by the end of the decade, requests for more power turned the original ATC90 into the ATC110 in 1979. The ATC was as evolutionary as it was revolutionary from the beginning.
The 1973 ATC 70
Good as the original fat tires were on snow and sand, they were vulnerable to punctures from things such as stubble from harvested crops. The fact that those original tires weren't repairable compounded the problem, so a fabric carcass was added, and steel hubs replaced the first hubless wheel design in 1975. Tougher, color-impregnated plastic fenders were added in 1975 as well.
Though it was primarily a recreational vehicle through the '70s, farmers were beginning to see the ATC as a tool to make their lives easier. Engineers followed their machines into the field, gathering data to guide the machine's natural adaptation to a rapidly growing market. The ATC was as capable at labor as at leisure, and America was catching on

In 83' the headlight/taillight/wire loom dealer installed option was the rarest of rare. Its a atc 90 tail light, atc 90 headlight, atc 70 wire loom, 6v bulb, and the forks had some headlight mounts that install into the front honda plate holes. I've found everything except the headlight mounts(factory stuff)..........this is a rare option folks and if you think you have it, you most likely dont. Because alot of cats ran headlights and various versions of aftermaket OEM combo over the years. Remember, other than 83' the option was never offered in the USA........and only a few dozen were even ordered in the entire country.
And the blue 83's are kinda rare, but not really rare. In California they sold a crap load. And honda made a ton. And they don't fetch any more or any less than there red brothers, and now that you can buy very nice blue plastic, they bring even less. But I think they are cool as hell.

It's an 83 and it doesn't have a parking brake. Looked at it yesterday and had Mom dig out the title.
The sticker on the side of the frame says... 1983. Just as my 1985 250R has one that says 1985... just as my 2004 50 has one that says 2004... as well as my 1984 200x that says 1984.The sticker is is better condition than almost all of my other bikes except the 50 and we have owned it since it was brand new.
My 1979 110 does have the parking brake.
My 1983 70 does not.

They are rare enough that I have NEVER seen one in 21 years of riding 3 wheelers.
I'll get the VIN for you though so you can tell me where it came from (was gonna do that with my 54 VW). That would be interesting.
It's always possible that the bars were replaced over the years with an older set.

My Mom and Dad bought it brand new off the showroom floor. All we ever did to it was add and change the oil and spark plug. The only things that are missing from that bike are the stickers on the rear fenders and the black plastic cover for the 4 bolts on the handlebars. It may be missing a tool kit but, I think that was on my TRX70 and the 110. It still has all 3 stock tires.
Nothing has been changed on this bike. It is 100% as it came from the dealer.
I didn't realize the subtle differences between these. Quite interesting. Is there a reason they changed the transmission shift pattern for the last year? Doesn't seem like they would have gotten much return on the investment of the engineering involved.
here's a link that has some year by year features...

This motor (motor style) I.E shifting pattern etc. has been used and is being used in Honda quads & two wheelers to this day.
I believe Honda continued with that motor in their 70 quads, which they went to in 1986 due to pressure from the public that the 3 wheelers were unsafe.
If you look at the XR50 & 70's you will see a very similar design.
So I'd say the engineering has more than payed for itself.
Toy collector. Not sure about your bars, but you know that the blue ones were a xmas promotion and assembled by the dealers,soooooooooooo maybe honda didnt have the parking brake on the blue ones? But I have seen mint ones with p-brakes 
Not sure. But I have a factory dealer assembly instrution manuel along with a factory owners guide to almost every one ever built and a few factory dealer manuels as well and magazine and adds, and they all support the 83 p brake issue, otherwise I wouldn;t be talking out my a$$. I worship the 70 and if Im wrong I am sorry, but not likely. I have a 70 fetish But Im in Ireland dring so excuse my typing, please.

The fork stop on the frame gets bent and the forks also can get bent, both of these are the main causes for dented tanks. Its very common. Sad also.

The fork stop on the frame gets bent and the forks also can get bent, both of these are the main causes for dented tanks. Its very common. Sad also.

That really sucks
oh well i could just have the body shop fill it when i get it painted 
OK SOMETHING NOBODY CAME UP WITH UNLESS I MISSED IT IS 1973 AND 1974 ATC70 HAVE DIFFRENT EXHAUST THE EXHAUST MOUNTS DIFFRENT IN THE FRAME THAT'S WHY THE REAR COVERS ARE DIFFRENT !!! 
Hi Guys
been reading these ATC70 posts for a bit now and figured I might add my 2 bobs worth. 73 ATC70 has angled silencer mounted in rear of frame, exhaust tip is angled and exits through hole second from top, 5 hole rear cover. 74 ATC70 has silencer mounted horizontal in frame, exhaust tip exits through hole also second from top but cover plate is 4 hole.
Also pretty sure 73 has no spark arrestor.

anyone want to take a stab at what SP WAMULASS stands for

THE 1973 EXHAUST AT THE BOTTOM OF THR MUFFLER HAS A BOLT THAT GOES THRUE THE MUFFLER FROM ONE SIDE OF THE FRAME TO THE OTHER AND THE TOP MUFFLER MOUNT IS A SHORT BRACKET WITCH BRINGS THE EXHAUST A A DIFFRENT POSITION. THE 1974 AT THE BOTTOM ON THE MUFFLER HAS TWO BOLTS ONE ON EACH SIDE OF THE FRAME AND THE BRACKET AT THE TOP IS LONGER WITCH PUT THE EXHAUST LOWER IN THE REAR AND THATS WHY THE REAR COVERS ARE DIFFRENT. THE ANGLE OF THE BAFFLE IM NOT SURE ABOUT BECAUSE I NO LONGER HAVE A 73 EXHAUST PIPE TO COMPAIR IT WITH A 74

Hi Tres
Thanks for the warm welcome, I'm a veritable mine of usless information, sometimes even usefull info too!
yes thats my site ATC Heaven, reading about these older ATC70s takes me back to the day when I got my first ATC, a brand new 74 ATC70, ahhhh those were the days.
Oh and my location is Newcastle NSW Australia.

Great to have you here Ric,
There are a few links here to your site, especially the 70 by year page.
Thanks for putting that up, has been a very good source for identifying 70's by the decal and so on.
for anyone that has not seen this it is right here:
Atc Heaven
Hope you don't mind the links Ric,
and once again welcome to the site.
Think you might want to make the 16 hr flight in mid march to attend the regatta?

My '85 shifts down also. Just ran out to look at the tag and it says 3/84! Quite a production window for the 1985 model year.
