ATC250ES front fork swap upgrade to 350X explained.
Вставка
- Опубліковано 3 жов 2024
- In this video I explain the reason why I swapped to a 350x front fork. I explain how I used an ATC250sx front axle tube and a brake flange bracket cut from an 82 200E front axle tube. We positioned it on the bike to measure fit and clearances. Then we welded the flange on to use as a mount for the 350x 0EM brake disc. I was able to maintain the disc brake set up and put on a modern rim with a 4/110 bolt pattern. I think it looks great and rides great too! Enjoy!

Nice wheels
was wandering if you could maybe help me out with a couple of links
Brehnden - links to what? 😅Check out the comments here. Over the years I have answered many of these questions lol. Certainly if I can help - I will.
Awesome Video Daniel!!
Nice! Looking to swap out my forks on my 84 200es. Your video was very helpful !!!
Any luck @TwistedMudders?
@@agwoodwork not yet. hopefully next month or two. may have to reach out to you for pointers.lol
Awesome build dude. I have a basket 250 es and I think I will be closley following your mods for mine. Kick ass
Hey right on glad you like! If you have any questions I'm happy to help.
Bad news, I WILL be taking you up on that offer.LOL. I paid 150 for mine. It was off of a farm and not pretty at all but it did start.
That story is a familiar one. I bought this one for $100 it hadn't run in many years and was sitting under a shack for lack of a better description. Everything was broken, the tank was missing, the rear fenders had chipped away to the point that very little was left. The rear brake was locked up, all tires were flat and rotten. Last but not least -the top end of the engine was locked up due to someone leaving the air box lid off and rain filling the box and rusting the piston in place.
Instead of adding an extra left hand master cylinder. Maybe you could adapt a distribution block like they use on Polaris ATV's and run the single master cylinder you already have. You will not be able to actuate your brakes independent of each other but it might simplify the installation.
Jimmy Jackson that is a great idea! I'll investigate!
Hope it works for you.
Thanks Jimmy!
Consider: instead of a digital speedo, use an old phone so you can run navigation and speed simultaneously. Mount cheap android in a waterproof case. It runs on GPS so there's no need to activate the device. Plus, it's a Bluetooth media player. :)
Ah yes you are right! I didn't consider such an easy solution!
Thank you I'm was trying to fix my three Wheeler 👍👍
really nice I have one... on Monday I ll test the engine.... your is awesome
Thanks! Love to see your bike too!
So going to find another 3 wheeler I love these machines
I need help anyone. I have a 1984 honda big red 200 and I wanna stick 12 inch rims on it how would I do this?
Austin l - join Honda Hoarders on Facebook or go join ThreeWheelerWorld.com. Honda Hoarders on FB is a closed group with thousands of people on it. They will be able answer the question. These older trikes have really small hubs and bearings. I would be careful how heavy a rim you choose. Good luck.
Is this possible to do with a 200 es. I’m tired of crappy front end forks /shocks. I really did mine and they’re still horse sh*t. And I feel the rear hubs are too.
Is the triple original 250es? Would the 250es shaft work if I used stock brakes and just wanted a lift?
I'm doing a 350x front end swap on my 85 250es. Where did you find a rotor flange to weld to the sx hub? I'm debating whether to use the 350x front hub and wheel with a 25x8x11 tires or to convert to a 250sx hub like you did. It would be nice to have a sx 4x110 front hub but the rotor flange is my hang up. Do you run 5x2 offset wheels also?
It’s been a number of years but I’m pretty certain I had an ATC200S front axle tube and we ground off the welds on that one and it was pretty darn close- the correct size. We pre-assembled and spaced the flange and the 350X disc. We had to position it and measure carefully to get the spacing right. If you don’t get it on there square with the caliper it will wobble and the disc and pads will get worn out really quickly. Possibly even damage the caliper. Btw you must drill new holes to mount the disc. So take your time. It’s been working great for years now. I purchased a rear disc set up a couple years ago on Honda Hoarders (Facebook) from Brad. It works well enough when used in conjunction with the front brakes. The rear disc really needs a larger master. Hope this helps! If you haven’t joined HH on Facebook you should.
@@interglactc thanks for the reply. I plan to do the brad rye kit in the rear, I just sourced all the trx450r brake components. HH is where I found out about his kit. My main goal is to make my 250es handle/stop better and more reliably. Thinking of running a 300ex rear shock to complement the 350x forks. Did you use the 250sx front axle or 350x? And are your wheels 5x2 offset? That seems to be what everyone uses when they go to a 12" wheel. Thanks again
The wheels are 14” they aren’t 5x2. They each have 2” wheel spacers front and back. The front axle tube is 250SX. The 350X looks just like the 250R which is cast aluminum I think. I think I used the 350X axle since it is still the correct width for those forks. They all use the same axle bearings. The SX axle tube was perfect length. I didn’t weld or bolt on the fork stops. So that’s one thing I haven’t bothered to do. I have a plastic Clark tank. If I had a metal tank I’d probably be worried about the bars touching the tank. The ATC250ES shaft spacer must be cut down btw. If you look at my other videos I use a lift bracket which is very common and very inexpensive. I wanted to keep the adjustability. This also enabled me to put the OE shock on its lowest setting for a nicer ride. I have ridden the hell out of this bike for years with this stuff on it and never had any issues. But she’s about ready for a top end. I use this bike to cut grass all summer here in TX. lol btw you’ll end up using the 350X handle bars. The BR’s bars won’t work safely. 😉
How did the 350x mount into the bigred neck in the frame. Any mods to do it or does it just bolt right up?
adam - it just bolts right in with bearing kit. The 350x shares same bearing. I ordered from All Balls.
@@interglactc thanks for the info I be looking into finding a triple tree soon
The Part is called a FITTING,CROSS (Junction Block) OEM part number 7052292. They are $30 on bike bandit.
Hey is there any chance I can get in touch with you on how I can set my185s like that with the front end and the brakes set up so I can get someone to set it up like that please if you don't mind
danny cannon - hey I don’t mind pointing you to some people that could help. I am uncertain about what other forks would fit on a 185s. I haven’t owned a 185s for many years. Most people aren’t modifying 185s in this way simply because they are hard tail bikes with no reverse. If you have a FB account you should request to join Honda Hoarders. There are tons of people with tons of experience on all sorts of ATCs and bikes. Once you join the group you can post pics and ask questions.
Greg Myrick sells disc brakes kits for the front and back of the 85 big red 250es. Find the kits on Honda Hoarders on Facebook! Just in case you didn’t want to switch the front end up is all.
Hot Fuzz - I had hoped that’d happen eventually! That’s great I just sent a request to join the group. I wonder what the prices are like
Intergalactic After joining the group just search for 85 disc brakes. Prices and pictures are there and Greg Myrick can help with any questions. Over 80 kits sold I believe now with hoaders posting up the pics of the kits installed. Very friendly group. Reach out before you buy. It looks like you have lots of mods and just want to make sure nothing would be in the way for the kit.
Greg - yeah we need to get one of your kits installed soon!
Do you have to convert to disc up front when doing this?
Or can I reinstall my drum from the 85 BR?
There are multiple reasons why you can’t reuse the front axle tube from the original forks. The main one is that the original ES front axle tube and drum are too long to fit between the 350X forks.
Did you see the 350 bore kit for the big red? Well i got my 350 forks coming any day and now working on getting bore kit. I am thinking a rear disc brake would be a must have with the added horse power of bore kit
Tim Burrier - nice I think I may need a top end rebuild one of these days and I'm considering the same 350 big bore. The front disc is nice but you really do need something in the rear.
Nice! I've got one as well and I love it. Type in Honda big red 250 " General Lee" if you would like to take a look
josh tyndall - I see! Very cool... and the Dukes of Hazard theme song too!
Where did you get those wheels and tires?
Brittany Cato - I think I have a video where I describe that. They are ITP wheels.
If I was to run rear wheel on the front. I would have to run a spacer right?
louizianaoutlaw85 - stock wheels are interchangeable anywhere on bike.
How much did the rims and tires cost and cost of front end 350x. Where did you get the rims and tires
hey man great videos just got a 250es myself just getting into it, it runs pretty great now just a bit rusty round the edges, any chance you could send me a link for those fork boots and the hand guards ? Keep it up man!!
Hey Joel, glad you got one! So it's been more than 2 years I'd say since I got those hand guards. I gave a quick look and saw many different types that could be used. I liked this style because they were kinda old school looking but probably anything you'd find for a modern Honda utility with 7/8 bars will work. The factory boots for a stock front end (32mm) are found on eBay easy as pie for $25-30. I want to say I've bought them on Summit's website too.
yeah thats exactly why i liked them there not to flashy and they would probably survive anything i've been looking around but cant find them anywhere, i've found the boots now! i'm afraid my left fork seal might have gone though haha! thanks for the quick reply man so useful having these videos up while i am working away on it no one in Scotland really has any of these or they're few and far between so these vids are a life saver!
+Joel Lawrie - eBay is probably the greatest resource for us on these bikes. I will usually check three standard places. First I look on eBay, then Partzilla, and then Amazon. Of course when searching always search for "ATC250ES" not BigRed. Although you will find that some people will incorrectly list their parts using things like "80's Big Red trike" of course when they do that you can often get some really good deals because no one is searching for that verbiage. The fork seals I like to use are the "Leak Proof" brand. They work well. I use a mixture of 40% ATF and 60% Lucas oil treatment. This mixture works well and it's pretty thick so it doesn't leak very easily.
What is the bolt pattern and offset for the front wheel? I'm doing the same swap with a 200x front setup on my BR.
Tyler Ball - I used 350x forks. They are very different from 200x. 200x is shorter, and smaller diameter as well as the brake caliper is on the wrong side. I used a 250sx front axle tube and had a friend weld a disc to the axle as a mounting plate for the disc. The 250es /250sx has a wheel bolt pattern of 4/110. I used a two inch wheel spacer.
whats the blue bracket ? id like to get one for mine
Fucking mad bro. Nice work
Joshua Whitton thanks for watching and comments!
one more question i got my forks on anyway how did you put key pad on. and did you search disc brakes on a. 250es big red that guy used a super atv kit its kinda pricey and not really a direct bolt on but with your 14inch rims i think it wouldnt be to hard.
Tim Burrier - nice! I really like this set up on the front. I've seen the Super ATV kits. What guy are you taking about? I really want to finish my rear brakes. I haven't made time.
Intergalactic just searched disc brakes on 250es on you tube thats the name of video i would send link but computer here at work sucks. so how did you put the key pad on?
Tim Burrier - oh I'm sorry man! I meant to reply on that. So my handle bars had a connecting bar that went from one side of the handle bars to the other. I think it was a mount for a water bottle or something like that. Anyway it's hard to describe these but they are sorta like clamps and since they held this cross bar in place they were naturally a 7/8 diameter just like the bars. So I removed the cross bar and slid these clamps down into the center at the lowest point of the handle bars so that they'd line up with the holes in the dash/key pad. I just used some long machine screws and put nylon /locking nuts on the back so they won't vibrate off. I didn't torque them down tight. I wanted some play in the dash so I could lift or slightly spin it up to prevent breakage.
So I am just a little confused. I have been researching this fork swap and ended up just getting lost with this fork swap I believe you said the 350 forks and triple tree bolt right on ? whats the part number or link for bearings. and would you know if 200x forks will work the same, just bolt on? The 200x forks seem to be more ready avalible and cheaper. And how about the rear disc you get any where with that yet? thanks for your time
Tim Burrier - the 200x forks can be done but they are smaller and the brake is on the opposite side. www.ebay.com/itm/172326654003
It's just not nearly as nice 200x forks are 32mm diameter tubes. The forks are longer making them easier to bend than the short ones that the 250es comes with. The 350x is 36mm I believe. So they are much more substantial and harder to bend.
On the rear brake I've been so busy the last year I really haven't made any progress. 😕
How did you lift the rearend?
Triston Clary - I talk about it in my oil cooler video. It’s a cheap easy mod
Intergalactic could you send me a link for one?
www.ebay.com/itm/232117658628
it comes with 2 did you use both together ?
Chris Garneau - no only one will work. You can't use anymore than 2" of lift or you'll bind the drive shaft
Intergalactic I just put one on my big red how's your holding up? don't seem like they are very sturdy or would last....im gunna use 1/4 in steel and weld up a bracket soon but for now it seems good
Chris Garneau - I have done some hard riding through everything you can imagine and I have had ZERO issues. I also weigh 265 and I'm 6'3
oh nicce to hear thanks!
