I bought a Blue honda atc90.

[racinjason68]

Well found it in a barn and after talking to the lady, I bought it. Now learning that the two rear tires are shot as in holes I am in a mess trying to find some. Anyone? LOL My boy is wondering if we are ever gonna get to ride it as we have no tires. So any options? It did come with 1 rear spare, so really I need 1 rear tire that can possibly hold some air.

Also not sure on the year but the VIN on the neck reads us90-122473

I plan to clean it up and take some pics. Not sure what to do with it at this point.

Hope to read and find more info on this bike! cool looking so far.

[rdlsz24]

I may be wrong, but you should be able to swap out the balloon tires for some knobbies if you just want to be able to ride it. You would probably have to swap hubs as well.

Rob

[racinjason68]

Well maybe a option... Would like to find just 1 ballon tire. LOL

I have located a couple but the shipping price is crazy.... Things we do for tires.

[portland250r]

u looking to put it back to its original condition or mod it?
if i was you i would go too any lengh to get knobbies cause that specific model bike is a hard fine.
i say restore it and make it look like it did when it left the dealership but thats just my opinion.
its your bike and up to you what u think is right for it.

congradulations you found a early model honda!!!

[racinjason68]

still trying to figure out what year and any other cool info i can about it. Well it come with the ballon tires so I figured that would be the best to find.

[racinjason68]

If it did have the tires, what is a bike like that worth? Moddin it worth anything? I have several toys and not sure I will keep or sell.

[rdlsz24]

Those tires are hard to find and will bring good money if in decent shape. I think that's a 70-71.

Do you not understand what that bike is worth?

[MonroeMike]

Congrats on the new toy.

[racinjason68]

Nope no idea... Just got it... Found it and thought it was strange with the tires and being a "blue" honda.

[three_wheelin45]

ok well dont destroy it. does it run and them tires are about a grand a piece

[three_wheelin45]

not trying to be rude or anything but u need to sell it on ebay to a collector. it dont need to be in the wrong hands :(

[portland250r]

if u do sell it im sure theres lots of members on 3ww who would treat that bike like a king.

[Tecate 50]

Thats a rare find.......I would restore it, but thats just me! I personally have never seen a blue 90 in person! If you decide to sell it, you wont have a problem finding a buyer!

[atc500x]

You can swap the complete rear from a later model atc90.I have a front tire in stock,hold air since 2 year,but NO thread,it's a slick!

[racinjason68]

Well I do not plan to destroy it. I have a quad for my racin and mods. I have not researched much on it. I would like to keep and fix up but right now, not sure so many other projects I have. But the right money and I may have to let it go.

[racinjason68]

I have a front, but seeps air, and my spare rear holds a bit but seeps too.... ugh.. Tire slime?

[portland250r]

heres another us90 website

http://atc90.tripod.com/hondaatc90/

[TheRealFatShady]

Anyone ever tried using Fix-A-Flat?

And if this old three wheeler is worth so much - even 'as-is' - I'd suggest selling it and using that money to buy one or even two complete working ones, that way your son and yourself have something to ride without spending any more/much more money.

[racinjason68]

I have seen those sites, or most of them... Just not sure what to do with it. Thanks for all the info! Not found any production numbers or how to read the VIN yet... LOL

It is not running but think it could with lil work. pulls over good and looks to be running when they parked it. Rear tires have huge holes in them.

[Vealmonkey]

If you really want to ride and enjoy the trike, then it would be in you and your wallets best interest to install a later model atc90 front and rear axle and ride around on more modern tires. If you want balloon, then you can find them at you leisure since people who have them think they are gold when 3/4 of the balloon tires used aren't worth beans. The rear axle swap is simply a bolt in and the hubs are no big deal either. You may be talking $75 bucks for the rear axle and all 3 hubs and steel wheels or maybe even cheaper if you shop around. I've seen people pay several hundred dollars a piece for used tires that are out of spec by the honda shop manual standards. If you were just going to display, then I would say use the balloon tires, but if you want to ride the trike, then you really ought to modernize just a tad and make it easier on you to get going. But it's your trike. You will need the rear brake drum from the years axle you swap out as well. The rear bearings should be the same. And you will have the added durability of a one piece axle as opposed to the stock us90 multi-pieces axle and hub spacers and such. Those trikes were made to fit in the trunk of a car. The rear axle comes apart partially and the front end will sort of fold up as well. But then you will be finding all of this out shortly. I would change the axle and hubs and ride it with modern tires and enjoy the trike.

[racinjason68]

as much as I would like to just fix up and ride, when it comes to one this old and original I have a hard time being the one to swap it all out... I think I would sell befor Mod'n the trike. The tires I found have holes and need patching so not sure worth much if I am taking a chance. Grrrr... May put bike back in storage and wait till other toys are out of the way.

[n10sivern]

If you plan to ride it, I would not ride it on the balloon tires. You'll have to get a rear axle and hub assembly out a later model 90 or out of a 110. The early 90's had a wide spline axle and there are no hubs that I know of that fit it. If I'm not mistaken, the rear brake drum splines are different too. All that will have to be swapped out to use regular tires. The balloon tires are prone to puncture and are worth too much to risk damaging. Cheaper to do the swap. I have a 73 and we took the hub out of the balloon tires and fabricated a hub to use regular rims. I would gladly pay for tht bike and shipping it if you decide to sell.

[racinjason68]

Depending on what I can get out of it will help make decision if I want to sell or keep... really I want to keep but ya know the saying. Money talks, and I have other projects to take care of.

[n10sivern]

Here is my 1973 mean green Honda ATC90

[racinjason68]

Awesome! guess maybe I should see about some parts...

[n10sivern]

My bike has quite a few dollars invested in it. Sandblasting, paint, tires, another set of fenders since the others were all busted up, and lotsbof other parts that were rusted to pieces or not working. The stickers alone were $70.

[Northman]

a blue christmas limited edition i believe, tires would be costly

[andrew j hyman]

Bike is 1970-71 I would think 1971 because of ser # . Mike from VMS has the parts you need to put New style tires tires n the bike. www.vintagemotorsports.net Ballon Tires are hard to buy Because most people do not know what is a good tire, NOS tire is apox 68 3/4 round with 2 psi in it. Need to make sure about Dry rot ect. Tires over apox 70 inch are not too good Will rub on fenders ect. I do have tons of nos parts for bike So does Mike from VMS . All depends what you want to spend? And what you want bike to be? Rider or 100% show? NOS tires could bring up to 4500.00 each good used tire apox 200. to 800 each ?

[rdlsz24]

For the US 90, blue is not considered limited or Christmas. You could get it in various colors: http://www.3wheelerworld.com/Brochures/ATCsite/70atc90.html.

I agree, restore that particular bike to original! The only place you see them tires, is in the Early brochures! Then you ended up with the blue on top of it. I would go with a factory restore also! There would be no question! Not to mention, just an idea for now. But you can put inner tubes in those tires.

[keister]

Just my opinion:
If you want a rider for your kids, sell that, take your profit and buy a different trike (heck, maybe 2) if you got that real cheap. Someone will pay you enough for that to buy a nice shape (running machine).

I have ridden a US90 just like yours and can tell you the handling is not like any trike / quad you have ever ridden. Due to the handling characteristics (and rarity and price) of those balloon tires, it is not a good choice as a kids rider.

Clean it up real nice, post up some good pictures, and watch the offers roll in from collectors. OR
Save it for a complete restore someday and buy another trike for your kids to ride.
I'm not trying to tell you what to do, I just want you to make a good decision.

[Daniel 250es]

What is it worth like it sits?

[oldskool83]

i wouldnt ride that bike, its nearly 40 years old. it should be cleaned up and sold. a honda dealer near me buys old toys in stock form to hang up and display. if you clean it up im sure you can get a grand for it. its too rare to swap things out and then ride.

if not put it in your living room for a converastional peice.

[Vealmonkey]

Wow. This thread is getting all blown out by alot of people who don't know. There's been maybe 3 people on here who have had good info. Firstly, no Christmas edition 90/110s period. And as for what Andrew Hyman said, bank on that. Andrew probably even has nos Baloon tires for sale. As for tubes in the baloon tires, NO! The baloon tires were molded one piece to the rims. Is it worth $1000, I seriously doubt it. Even though the trike seems fairly complete from the pictures you've posted with little or no detail trikes aren't bringing all that mauch, but you could get the 2 bidders on ebay who just have to have this trike. But then again, you could get the schmoo that bids the trike up and then retracts his bid at the last minute of the auction and there you sit. Put the trike on CL and you'll get the guys from Africa who offer to send you a $10,000 dollar check and you send them your trike and the change. LOL IF you want to sell, take your chances, but I don't think you'll be turning this trike into your kids college fund. Don't expect high numbers, if you get them then you are lucky, but don't be disappoionted if you don't. And to do a rear restore on this trike, the tires willl be 75% of the cost of the restore. Just ask andrew or vintagemotorsports. They provide nos parts or vintagemotorsports will restore your whole trike. Vintage has done trikes for the "Honda Museum" in Japan! They are the real deal and they know and do this for a living. Best of luck with whatever you decide, but don't get caught up in what most of these people say that you are sitting on mechanical gold. You have a nice and neat trike, but the value is determined by the buyer and what the market will hold. And except for a few certain parts and a few certain crazies, well, alot of people have been disappointed by listening to alot of people who just don't know. I'm not trying to discourage you as I'd like to see you fix the trike up real nice and ride it around with non balloon tires. If you want to really put the shine to it, then I would advise you make it as nice as you can afford to and put it on display with whatever balloon tires you can get. As far as a restore, very few people on here have had thier trikes "restored" as they came from the factory. That is a serious commitment of time and money. But I can say without a doubt that vintagemotorsports are the people for the job if that's the way you want to go.

[racinjason68]

Thanks Vealmonkey! I feel you have offered some good sound advice. It has not really been my plan to "fully restore" the trike, nor do I wanna just fix up and let my son ride. I would like to see it be somethings of some value and setting in my garage with my other rare ride...... I plan to clean it up, and post some pics and go from there. If the right offer comes along so be it. Until then it may just stay in the garage. The spare has a crack and seems to leak some air so not sure if it is worth the value as one said to buy other tires.... The front is the same way. I knew the tubes were never gonna happen as I can tell it is a one piece wheel and tire.... Maybe on some honda site I can find out more about the "VIN"....

I have learned alot and several have sent pm's, so it must be worth something.... I will not sell till i get better Ideal on bike. Also was invited to bring it to a night class for small engines and we tear it down and clean it back up and get it running. Sounds like a cool project for a night class......

Thanks for all the info so far. Still reading.

[3wheeledjunkie]

Clean as good as possible, buy that one tire. Sale to a crazy collector for an ass load of money. Then buy a trike that's more common and easier to justify riding.

[racinjason68]

Not sure I will buy a trike.. My car needs money and work. I already have 4 quads. LOL also have a buddy wanting to sell his '83 125. May buy it for playing...

[vintagemotorsports]

How did i miss this thread till now, Lots of mixed opinions here . I can tell you right off i love seeing US90s coming straight from the barn they are just too cool to look at and just think if that machine could talk the stories it could tell you about the last 40 years . Just think about it thats a long time ago when these bikes started a whole new sport . I can answer most of the questions in a few short words . Is this bike worth any large amount of money answer NO. Is this bike an all original 1970-71 Honda US90 K0 in aquarious blue it sure is . everybody asumes because its old and rare its worth a mint its just not so realistically this is a $300 bike all the hard parts that are needed to pull off a nice resto are junk #1 item the tires . I would love to see a bike like this one become restored back to its original glory witch I can do for the price tag off 10K , you really have to have a strong sentimental value to something to commit to a project like this , but I think it would be just as cool given a good bath and a major detailing and hang it on the wall for people to admire . if you need parts or advice shoot me an email mike@vintagemotorsports.net
below are some pics of an aquarious blue US90 I restored . cool find you got there enjoy it !! Mike

[racinjason68]

My problem is I like the used look. How it is to me adds character. Will I spend 10k on this bike, no way. I may keep it and put it away for now. Think the value in like 20 more years. Lol. Thanks for the heads up and I maybe in touch.

Thanks, J

[racinjason68]

I am open to offers. I am not gonna put much effort into selling, due to I am not sure if I wanna sell right now... But money talks.

So dont expect me to make phone calls to sell it. LOL And the 100 dollar offers are not gonna work. LOL

[n10sivern]

i don't know what you are expecting to sell this trike for but i wouldn't sell it for $100. however, i don't believe it is worth much more than that, probably $200-400. it'll take a quite a bit of dollars to make that baby nice again.

[racinjason68]

I agree. But someone wants it enough, it will happen. I have had offers. Like I said, not in big hurry to sell.

[Fungo Wizard]

Where you at in OK?

[racinjason68]

Ponca City. I am wanting to sell it, wife says to many toys and I have quad that needs work for this season. I cleaned it up and really wanna try it out but know if I start in on it, it will be never ending....

[racinjason68]

I also have a spare tire. It has cracks and leaks air, like the front tire does... I was going to try tire slime but figured I would let the new owner make that decision.

[jason85atc250r]

Good luck with the sale but your going to have a hard time time over $300 for that one in it's condition. i bought my 3 for under $200 each on ebay in the same condition.

[racinjason68]

May go back into storage till I am ready to "mod" the bike to use newer wheels and tires....

[jason85atc250r]

the 76-82 atc90/110 rear axle and 76-85 front wheel assembly will bolt rite on. The 1971 us90 like yours the axle housing is the same so just get a beat newer one and swap the rear axle and all the parts over. Then you dont need the adaptors and get better axle asembly to boot.

Did that to all 3 of them since tires are so expensive. Did no cosmetic work to them just swapped axle parts and got them running

The red one with the orange front end ( must of had a mishap back in the day) i just stole the axle parts from a beat 1980 atc110 and it has 84 bigred wheels and hubs

the 1st yellow one everything is from a 1976 atc90 even the motor. Both yellow ones had bad trannies i found out after i won them. 2nd yellow has a aftermarket bandito frame i got with a axle assembly for $100 on ebay and has a 85atc110 motor and front wheel assembly stolen from trike with broken frame that runs perfect.

Did this bike ever sell?
If not I would interested in buying it and having it shipped to CA
