swingarm broke

[JohnnyP636]

That's crazy never see that happen before
Did you fly over the bars when you mouse trapped I usually do lol

Its actually pretty common with the F4i to break in the exact same way....Theres more then a few people on SL and SR that have posted the same kind of experience......F4i not so bullet proof I guess....

Now that you mentioned it I have seen those pictures before I'm just a burn out haha

U need re-enforced swing arm now

[2kgixx]

do you think rr swingarm conversion would be the way to go for f4is? Or are they just as fragile

[RockerGuy]

imagine wheelie-ing down the highway only to find your swing arm 10m behind you

Theres one thing about the F4i/600RR swingarm swap that I would be a little concerned about. When people are doing this mod they are using a mount on the bike that was not designed to carry swingarm load. Basically there is another set of bolt holes right below the original mounting location, and people are using that.

Its much weaker looking and was not designed to hold the swingarm

I don't think its common at all, made a thread On SR and sounds like its pretty rare. Especially on a bike that was made for 8 years and probably the most common stunt piece to have 3 swingarm's snap is A rare thing IMO.

Theres more then 3 people out there that have done the exact same thing as you, those are just the pictures I could find during a 2 min google search.....Ive seen many posts about it.....Its not as common as some other bikes failures, but your definitely not the first person to break an F4i swingarm in the exact same spot....

Few post from your thread on SR confirming it happens

didn't happen the first time, heard about that before, glad you are ok!

I've seen a few broken f4i swimgarms. They all break at the welds like the one in this thread.

Ditto, this is not the first time its happened

Yup...Heard of this before.
ANOTHER reason I would NEVER own a f4poop.

i've seen two f4i swingarms crack at this same exact location, always monitor that weld!

yep, i had the same in 99 f4 2 years agonormal leaving the bike to 2 wheels!!

My swingarm was cracked underneath and right at those two spots for a long time before I noticed it , never snapped but when I noticed the crack I'm surprised it didn't !!

I've had that same crack in my swinger for bout 3 years now....
