I have a FI bar on my 04 GSXR 600 at the mount. I am breaking my sub frame all the time (at least once a week). More the less it seems to be NOT from scaping, but from the bike falling over and rolling to hit the bar. I am looking into alteratives. I saw saw the Sick Innovations round bar on there site. Does anyone have it and if so any problems? Let me know!

Thanks.

I have the sick innovations round bar on my f4i and its great, no problems whatsoever but your on a gsxr and those subframes are just weak to begin with..

Dean Ellis

Thats the problems... Haha

brace the subframe with metal strips from front rearset to passenger peg bolts

Bingo ! Get a local welder to place a few strips in the right locations.

Between the rear footpegs.
Between the upper and lower tubing on the subframe.

We also cut custom strips that fit over the subframe mount to the frame..

That seems to make a big difference..

Oh and the other thing is to always make sure your subframe bolts are tight.
Eventually they will ruin the thread in the frame and you will have to put locknuts behind them. Once thats done you should be good to go..

or if ur going throught that many subframs its time to buy a steel one

Lunchbox-

RACING 905 round bar... never broken a subframe.

Re-enforce it then it's easy.. You can gorilla scrape that sh*t all day if you take a min and add a few welds... Not hard at all... Bunch of cry babies I swear..

Let me guess some f4izzle **** slobber is going to say "get an f4i" because of a subframe..

mikkee

Very true.. Keep em tight.. 1 way is to start with the locknuts on the back to begin with..

mike1984

**** slobber? dont hate cauz the gixxer frames **** @ss and whats bad is you KNOW they are!!! you even say "Heavy PIG 750 w/ 4 reinforced cracks in the frame....." in you avatar.... i mean dont get me wrong... i like the low end grunt of a gixxer.... but the frames really are

Dean Ellis

How did you enforce yours?

Street Warrior

905 makes reinforcements but it's easy to make your own, just get some 1 1/4" x 3/16" x 16"(or whatever length just cut it) flat stock steel from home depot and bolt it from your rear set to your pass peg.

Ho_Hey

SI round bar on my f4i and love it!

mikkee

Took 3yrs of pancakes to crack.. $100 for pimp plated welds that will never crack again... Don't kno how that is crappy being that none of these bikes were made to be dropped anyways..

Don't get butthurt.. This is about SUBFRAMES... stay on topic hater..

mikkee

Well mine wouldn't help you since it's a different subframe... But I'll take pics of my roomates 05 750 that is the same subframe as yours with all his reinforcements and post em up 4 U.

"get an f4i":YEAH

f4stunna

I cracked my sub last night doing an endo.. It has prolly been weakend from the bar but the endo did it in. I was missing one bolt up front and I'm sure that had a lot to do with it. Does anyone make an aftermarket subframe worth buying? Also I am thinking of making a jig and fabing a tubular subframe either A- one made out of aluminum square tube and plate similar to F4i. OR B- One made out of steel square tube and plate. Has anyone seen a steel sub put on any of these newer bikes? I am just to worried about braking frame tabs even with the rearset brace.
