so i READ alot of threads about "welding" the subframe.....

would this help against crashes on my f4i? and if so, what are you supposed to weld? OR what do you weld it to?

Herb

Weld it to your frame soo it wont have the possibility of ever coming off.

I'm not a huge fan of welding, I like to put steel reinforcements on. A lot of guys will tell you the f4i doesn't need it, and they are probably right. Infact no bike should need it: If you have a short 12 bar, or a round bar, and some throttle control, you shouldn't be slamin the subframe anyway.

Out of habit (owning a gixxer for a long time) I reinforced mine anyway.....

N/A

Never have had to reinforce mine, but I do need to tighten all my bolts up a lot. Thing comes loose all the time.

lock washers or locktite will do the trick^

N/A

It's the bolts on the back of my subframe. They come loose no matter what, even with RED locktite. I like to do bar tricks and usually always rock foot on the seat and it just wiggles loose over time.

ahahah you do bar tricks!!! ahahhaha


only issues i've had w a f4i subframe is if your pegs out and it pancakes, it can crack the pass peg bracket tabs... mine is cracked big time, haven't been able to do staggered in like 7 months.

N/A

Don't lie dude, just tell everyone the truth that F4i rear peg mounts have a weight limit and anything over 300lbs will snap them like a twig. Lose some weight fatty!

crtchrktrcr

no idea why you had to do that shaun... ok, max weight limit is 280.. if i'm in staggered it's only about 260lbs on there.. but i lifted my brake foot for a can can... and yeah, it was like a nuclear bomb went off in my subframe

N/A

Poor subframe never even stood a chance!

i can't see **** from that pic...what do you mean by "reinforcing" it?

old man roger

click on the pic ....

there is a bar going down the side of the subframe

inolen

You don't need to reinforce it.

If you hit it hard enough to break the stock one then I doubt reinforcements would help (something else will break or it will just tweak bad or something).

DirtyToes

i have to be blind cause i don't see the bar you're talking about.

DirtyToes

would a 12 bar help the situation...at all?

JB

dont know how to post pics, but there are some here. check out the 1st stoppie pic and the last wheelie pic. i'm on the black gixer. have a look at the flat allow strap i have from the rear set to the passenger pegs.

ohh i see. has that helped or u dont know?

what about the 12, would you say that its ever helped? (the subframe)

inolen

Like I said, you don't need to reinforce your subframe.

I've popped out my clutch while doing a rev limiter coaster and my rear wheel came off the ground I hit my bar so hard yet my subframe did not budge.

If anything, a tail is going to slightly lower the cushion the impact on your subframe if you loop out.

Quit worrying so much and go practice.

N/A

If you use an FI 12 bar you won't have any problems!! But if you weld up your own 12 bar and it's ridiculously heavy well then you'll snap your subframe pretty easy.
