inverted forks for f4i

i was looking through a bike magazine and came about the bruce transportation group racing team and noticed that their f4i had inverted forks. has anyone personally done this mod and give a few tips as to where to begin or what forks to get?

Which magazine was that? Are you sure it was the F4i, and not the 954? I know that Erion uses standard style forks on their F4i, so I cannot imagine that Bruce, who gets mucho support from Erion, uses inverted forks. And if I am not mistaken, the rules would not allow such a change from standard equipment (in the same vein as the chassis restrictions).

definately f4i, it shows the front half of the bike as well as part of the rear... everything looks just like my bike except the front inverted forks and the seat, shocks, rear set.

go check it out. maybe there's something i'm not aware of.

Thanks, I'll look at it when I get home this evening.

In the meantime, take a look at the attached photo. If it's not clear enough, you can go to this link and enlarge it...

I think it's their 929 from last season. One big difference between the 600 and 929/954 is the way the swingarm mounts. The 929/954 has a "pivotless" frame, and the swingarm hangs off the back of the cases. While the 600 swingarm pivot passes through the cases, it bolts to the frame. Look closely at the smaller inset photo. You'll see that the frame ends just above the countershaft and swingarm pivot; that's a 929. On a 600 the frame extends downward and the swingarm bolt passes through it.

I made it home before seeing your post, and DataDan is correct as I suspected, and you, my friend, are wrong. That's the 929 with F4 bodywork to accomodate the ram air. Look at the tank. Look at the swingarm. Look at the rear plastics. Look at the subframe. And as DataDan points out, look at the frame.

If you're still interested in inverted forks for your F4i, I'd suggest contacting Dan Kyle of Dan Kyle Racing.

Your chances are a lot better at a baby oil wrestling session with those pit bunnies than getting your mitts on a pair of those works forks!
