well, my boy high-sided his 02' f4i at about 40 mph. he's allright, just rashed up good on his right arm and back. the bike wasn't so lucky. it barrel rolled a couple times then slide on its side about 30 ft. left side fairings are trashed, subframe is bent, front clip is not too bad. i know f4i's are tough as sh#t but the frame cracked where i circled an f4i frame in the pic. my boy is gonna fix the bike if this can be welded and made good as new. has anybody ever seen an f4i frame crack there? :crazy sh#t.

 

yea it can be welded..but just make sure hes a good welder...ive seen acouple of bike with cracks in weird spots...

 

cool, he'll be glad the cast aluminum can be welded but has anybody ever seen an f4i crack at that spot before? just curious

 

is that were the subframe bolts on?

 

correct

 

I don't see why not.

It is a small weak point. Im sure the subframe is TRASHED, so just consider the amount of force put onto that one bolt area while it was flipping down the pavement. At least the tab wasn't torn clean off, like some other bikes do.

 

the subframe is twisted garbage. i've just never heard of an f4i frame breaking there. never heard of anyone repairing that spot.

 

yO i took an srad to the frame shop twice!!!
most of the time when the sub gets shreded that shyt brakes clean off or like in my case gets twisted all uP!!
find a real good alloy welder!!!
the right guy can make it like new NO PROB!

...an hope your friend heals up quick!!

 

i think it is common to see the frame break there on f4i's. i know in the stunt world that is where they usually break. but that is just my

 

I`ve Seen Them Break There,but Its Always Because Of A Bad Case Of The Gorilla Scrapes

 

i wore the freakin search function out trying to find something like this and nuthin.

 

if it rolled that many times and hit and skidded all that time id be glad if that is the only thing that cracked.

i guess those bikes really are bulletproof

 

It's not hard to break those frames at that point though, subframes always do that if you slam them way to hard.

 

anybody got a pic. just want to compare to my boys bike

 

anybody got a pic they can post up. just want to compare to my boys bike
