can some one post up some type of dirrections to making a 12 bar? pics of home made bars and so on i am going to be making a bar i have a 94 900rr how do i go about doing this? well thanks for all your input!!

shawn

 

Post pics of home made bars for F3 cbr's. Im thinking of getting one and will be making my own bar...

 

we need pics of 900rr's

 

Do a search for some

 

www.terrehaters.com

go to archieves, then "tweak's 12 bar" near the bottom of the page.

pictures and details. very simple design and hasn't failed me yet.

i have a 94 900rr that i'll be making one for soon, i could start early and give you tips on how it went if you need them. it's pretty simple though, 2 bolts each side, 1/4" steel plate, that's about it.

 

cool thanks for the info Binder929. I am thinkin of building a 12 bar for my 03 R1 soon just I think I'll do a little sub frame reinforcing while I'm there. What do you think will the sub frame be okay without it or would I be better off reinforcing it while I'm there. Keep in mind I have all the materials to do this at work and I won't be drilling the sub frame whatsoever with my 12 bar installation.

 

listen to this guy he knows what he is talking about, told me a few things a few weeks ago, im rockin 12s now no prob

 

there isnt a problem with drilling the subframe as long as you stuff it first, (thanks to JackassRR) i have a gsxr not an r1, and my subframe is 3/4" hollow square tubing, i went to lowes and bought some aluminum strips, and forced about 4 in a row on each side, then when you drill through, and bolt it on, it is a solid piece (well almost solid) so it wont collapse, what jackassRR said to do was to get a solid tube .625" and mill the corners a little and it will slide right it, then just weld up the end and it is stay put!!!

 

can you weld? i just copied one off freestyle inginuity for my zx6r, it turned out a little different but it worked, well i never landed one but it didnt break

 

ya, you need to drill.

i drilled 2 3/8" holes in each side for mine and bolted it with grade 8 bolts. haven't had a single problem yet and i'm pretty rough on it. I've crashed some hard 12's and even flipped a crazy fast stopped and watched the bike go end over end and it didn't break my bar off or mess up my subframe.

just make sure you center the holes. putting something inside it doesn't sound like a bad idea but wiht 929's you can't because they have a crazy bend in them at the end.

i didn't reinforce my sub frame, but it's also a honda 929, i think one of the more stong subframes. bolts on 3 places, pretty stout. on r1's i think they are alittle weak so if you can aluminum weld some bracing, i'd go for it.

 

i got this on lock man i built one for my 94 RR myself ill send you pics and specs if you need jus pm me

 

oh yea and please muffler clamp that bitch cause drilling holes loses strength and i dont think you wanna be the filling in a 400lb taco when the sub snaps

 

i've saw muffler clamps break time and time again.

i've never had ap roblem with my drilled subframe, that's how all my team mates are and nobody has had a problem yet. i even flipped my bike end over end at 80 and the subframe bent, didn't even bother the bolts. also, tha'ts how freestyle bars are hooked up, if there is a problem with it i don't think they would tell everyone to do it.

 

well "Freestyle cages" break frames dontcha think they would tell ya...lol...i use clamps that i retrofit with a peice os 1/4" flat steel that i drill out for the backing plate....when i was learning i SLAMMED that **** on the bar and it never so much as moved....and im not 140lbs bro more like 297lbs...just my opinion man mines never slipped or damaged the frame nor has any of the others who have em like that that i know jus my .02

 

3/8 holes are little overkill plus it weakens the subframe, i used 1/4 bolts in mine and we used 1/4 in all my friends bars too. Clamping seems to be a better idea though.

 

fill your current subframe with alluminum, so its solid.

 

I could only fit one roll of foil in it. Is that enough?

 

I MENT TANK A .625" OF ALUMINUM AND SHAVE THE CORNERS AND PUSH IT INTO THE CURRENT PORTION...MAKES IT SOLID..

 

that's cause gixxer frmaes are small, on my 929, 3/8" left plenty of room on both sides, it wasn't taking up much of the subframe. like i said, ti's been flipped at 80mph and hasn't had a problem yet and neither have any elses bikes i've put bars on.

 

well whatever works for ya man...i know mines strong as hell....i like the filling the subframe part...only thing is that makes it strong enough to damage the frame itself...double neg. there huh
