86 250r subframe...

[250rRoostmaster]

Hey i just got an 86 250r and noticed it have a sub frame that can pivot under the seat section.. Just wondering if all the r frames are like this or if it's somebody modified it before i got this bike?? :wondering

[Kintore]

Like flip up??? pics please!

[250rRoostmaster]

Yeah it flips up, it has hinges at the top and they slide over the posts at the bottom,. i'll post pics when i get home later...

[250rRoostmaster]

I've looked at alot of R frames and didn't see any that had this so that's really why i'm asking

[bigpimpin]

pot pics sounds cool

[D-dub]

maybe its an ultra rare aftermarket frame from the 80s

[Red Rider]

Somebody has modified that frame. None of the stock R frames ever had a detachable subframe from the factory.

[dcreel]

Was it Laeger that sold an atc 500 frame with the flip up subframe so you can kick it rearward?

[NINJA]

Was it Laeger that sold an atc 500 frame with the flip up subframe so you can kick it rearward?

Yes it was. It was a kit to transform a CR 500 into a trike. On another note, CT used to sell an aftermarket aluminum subframe that would attach to the stock R frame after some modifications.

[250rRoostmaster]

So here are a few pics i snapped this morning, you can see the hinges at the top of the frame and the posts at the bottom, the guy i bought it from tack welded the posts so it wouldn't slip off:( and the gas resivour for the shock is also welded to the frame and the subframe so it doesn't pivot at the moment:crazy: But with some cleanin up it should go back to the way it was but my only question now is where to relocate the gas resivour and the how to get the air filter to work cause the stock one obviously won't work with a pivoting subframe, it's got a K&N filter so should i just take off the stock airbox and run it without it or just weld the damn thing together and forget about it?? If its a rare thing to have this frame then i would like to keep it since it sounds like it's pretty rare...

[RodKnockRacing]

I looks to me like the sub frame broke at one time and who ever had it just cobbled it together i would find a frame and go from there

[250rRoostmaster]

the frames in pretty good condition and there are posts that the subframe slips over so i don't think it was ever broken

[Vealmonkey]

I really don't see a practical use for a subframe that pivots forward. And it doesn't look like there was any way to latch the subframe down. It probably bounced alot in rough terrain. If it was on another trike where a rear kicking engine was custom mounted, it may have been a help but I don't see where it would make much of a difference on a relatively stock R. And it doesn't seem to have been very well thought out at all. I would be cool sitting around the campfire to show off the back end of your trike, but that's about it as far as I can tell.

[250rRoostmaster]

Thats kinda what i was thinkin so i'm probably just gonna weld up the subframe to the posts and leave the hinges on top and get the whole thing powder coated black and go from there...

[Vealmonkey]

Just be careful. These honda frames aren't the heaviest duty frames I've ever seen. And since your frame has already been welded on several times, it may have actually weakened your frame. It's your trike and your call, just be aware all those previously welded spots could be possible problem areas. If you do alot of jumping or really hard riding. Make sure to check those spots for cracks. It's better to be safe.

[250rRoostmaster]

Yeah i have thought about that,. that's why i'm making some custom gussets for the frame and i have a buddy whos a full time welder so i'm gonna have him do all the welding for me. Thanks for the concern though!! :beer

[dcreel]

That doesn't look to me like it would pivot. The way they were cut was to make a way to fasten the 2 posts together, not a pivot. Since the ends are squared and in close contact I think they would interfere with the pivot.

[AutoXer]

personally if you are going to powder this i would look for another frame (makes reassy much easier) not alot of money involved in a r frame

[250rRoostmaster]

Why would reassambly be easier??

[Dirtcrasher]

I looks to me like the sub frame broke at one time and who ever had it just cobbled it together i would find a frame and go from there

Looks the same to me........ Shock resi mount, hose clamp, exhaust support. Just looks like it was made to run.....

No worries, it can all be fixed up :D

[250rRoostmaster]

Well i guess i'll just have to work with what i got.. Kinda feelin like i got hosed on this deal Dammit but i'll have to make it work out:cool:

[dcreel]

Is the resi mount welded between the frame and the subframe?

[250rRoostmaster]

Yes it is....

[dcreel]

Yes it is....

So then how is the subframe removable at all?

[250rRoostmaster]

Well like i said before it has the hinges on top and the post on bottom but the dude who had it before me welded that piece in there so its not able to pivot at the moment

[250rRoostmaster]

I really don't know what his plan was with the frame but i'll get it all straightend out, i'm makin some gussets now to fill in the corners of the subframe to strengthen up his mistakes

[Dirtcrasher]

You'll be all set....... I use .125" steel for nice thick gussets!!

[250rRoostmaster]

yeah i saw your work with the 350x frame man!! Good job on that,. it looks like it was supposed to be there!! I'm using 12GA which is basically .125 so it'll be nice and strong plus at my work i have a laser so i'm doing some cool writing on them as well to make it look trick :cool:

[leviblue]

forget that and just get a new frame....looks dangerous and non-funtioning to me

[250rRoostmaster]

The guys before me was 6' 4" and weighed 300 pounds and he never broke it the way it is now, i talked to him and the frame was like that when he got it so i know it's obviously strong if it can take a 300 pounder that rode hard for 4 years!! And when i get done with it it will be much stronger :cool: If i could find a frame around i would but theres not much in the frame dept. around here unfortunatly... So i'll work with i got

[AutoXer]

it is easier because you can take a part off and put it on the new frame. It saves you from having to completely disassemble, refurbish, reassemble. But if you have looked and can't get a frame then i guess its not a option

[250rRoostmaster]

Ahh i get it :beer Yeah there's alot of parts around here but no frames that i've seen

[deathman53]

yes, CT used to sell a removable sub-frame for a atc250r, they also sold a front hub, some kind of swingarm and more. I have everything they sold for a 85/86 atc in a mag somewhere. Maybe you got one of those very very rare things. I called CT about those parts in 04 and they said they haven't heard anything about about those parts or knew they made them and asked the old timers. One of them got on the phone w/ me and said that today was the first time in ~15 years that someone asked about those parts. If there is enough demand, they still have the jigs for everything they sold for it. I have an atc250r w/ removable sub-frame. Also I am going to have a atc250r-like w/ a flip-top seat. Both are custom frames, both made by HRE ATV

[250rRoostmaster]

I can't tell if this is one of those aftermarket subframes or not, it looks legit up close contrary to what some people have said on here

[Eric250R]

I would investigate a little more before I just welded it up. Maybe it's a rare piece...maybe not, but I would want to know for sure before I hit with a welder. Maybe a few of our older ( and wiser....lol ) members can weigh in on this.

[bigpimpin]

someone drilled the gussets as well

[deathman53]

after seeing the pics, that is just a welded back subframe that bent, broke or was removed/modified for some reason. here is what a professional removable subframe looks like http://www.pictureposter.allbrand.nu/pictures/deathman53/top+veiw+side.JPG.html, the picture maybe too small for some to view good.

[250rRoostmaster]

Yeah this doesn't look like that... but when i'm done it shoould look pretty trivk with a few extra cool things that i have planned for it!!!
