My frame has cracked all the way around where the vertical frame rail meets the horizontal frame rail near the pegs. I just got a mig welder and welded the crack all the way around. If I make a gusset in this shape would it help take some of the stress off that spot on both sides? This is of course, assuming the gusset will not get in the way of removing the cases or anything else. I have a spare fully gussetted frame so its no big deal if it doesn't work.

im not sure but i have a similar problem on my frame above the pivot bolt i was gonna weld a gusset to support the whole vertical piece and tie it into the top and bottom

also on your spare frame did you use a gusset kit or make your own?

slightly extending and definitely beefing up that area is a pretty common and definitely useful gusset.

I bought my spare frame gussetted. I was thinking that it probably wouldn;t be that hard to buy a 400ex gussett kit and modify it to work. Heres some more pics of my spare frame so you cans ee where it has been done.

Rath racing makes a kit that is pretty good. It boxes in the pivot bolt area.

Dave is the man if you want gussets on your R frame...he has done many and does some of the best work i have seen.

thanks im probubly ordering a rath kit i spoke with b.a.r.e performance they are making a kit that should be avail. the end of this month but ive heard good feedback on the rath kit the bare is new so i think ill stick with rath

BUT im still open to suggestions on other kits for gussets

the trx250R frame only needs what you see hear in the link to the thread below ,..no more no less

more is a waste & can make the frame too stiff ,promotes more breakage at times
less is ineffective for preventing breakage ,cracks etc ..& wont handle hard core rding /jumping etc
I see how people / riders add all those ridiculous lil triangles ...& I think why ? I guess some dont really know what it takes to get the right balance ...so they just "hope" it works ..

the pics are of a proven a method & areas that frame needs to maintain some flex & still adds stength to prevent breakage ..

there is even a LSR kit(39 pcs I beleive) out for 450R that is an overkill & IMO is a waste ,too many parts & will probably promote more breakage than help ...
how do I know ?? .. I did one recently ...I didnt like it & but my customer wanted it ..so he got it !

just because it s available from a big name co. doesnt mean anything except .. when you buy it ...they make MONEY!!! B)

I bought a frame off ebay for 200$ and it has a full 1/8th inch thick steel skid plate welded solid on the frame and some pretty hardcore gussets around the swingarm bolt area (this is where I was having alot of problems with my original frame). so far it has held up to some pretty rough, fast paced trail riding and has worked great. theres a few pics of it from where I was installing my new 89 aluminum swingarm.

it would look better if there was a plate on the front tying the two pieces together.

 

[2R's]

well IMO thats an overkill ...the added weight is not needed ..& does nothing
my work looks much better if I do say so my self

yea your frame does look pretty slick, but I dont see anything wrong with mine. to me it looks freakin bullet proof and with my solid welded frame skidder, I dont have to worry about anything when im pounding through the woods, over rocks and logs. I know it is a good 10 or 15 lbs heavier than my original stock frame, but the way I see it, that solid welded skid plate makes the frame much more stronger and rigid. sure it wont win any beauty contests, butit gets the job done

yes it is more rigid.... but it has its ups and downs.
the frame is stiffer and probably can take a hell of a beating.
but with it being so rigid there is no flex. if the frame can't flex then it's going to break.
imo it's a fine line between just enough and to much.

you can see it anyways you like ..fine by me ....
hope all the extra weight & inconvenience of the gussets & skid are too your liking also

I am sure I am not the only that knows sometimes you can't always have bueaty & design but for a mere 200 you did you what you paid for !!

he has the key ^ here flex is very important ..mine have been tested over many years & have not received a single complaint to this date

I did a frame up rebuild last summer where I added gussets to my frame. I did a bunch of research on this topic and compiled all of the pictures that I could find where other people have gussetted their frames, whether it be on here or other sites, and did my best at replicating them. If anyone would like these pictures I could email them to you, just send me a PM and we can go from there. I'd post them, but there is just way too many.

Anyways, here is what I ended up with as my final product. As you can see, I basically copied Dave's (2Rs) design (Thanks B) ). This being my first time doing something like this, I think that it turned out pretty good. Enjoy.

I just find it hard to believe that any 250R frame, no matter who works on it, will hold up to hard riding. And Im not talking about your average mx rider jumping 80ft jumps and getting 10ft of air, Im talking about 110+ft jumps and dropping a quad from 30ft in the air. Out of all the quads Ive owned I have never had a stock frame hold up and Im even having second thoughts about trying my gussetted frame. I might end up just getting an aftermarket frame and hoping for the best.

 

[86 Quad R]

honestly!!! even an aftermarket frame being ridin under the conditions you mention will start to come apart.

^ tru dat !! ..nothing is undestructable ... & please know ..a good (not used abused) suspension goes a long way ....to keep frames,swingarms & A arms intact..
the suspension is where a lot of so called MX riders/racers cheap out ..then break stuff & cry !!
