assume so.

but im not sure why you would still want the upper parts of the F2 shocks.

F3 stuff is just better, newer technology.

Default New guy alert!

Hey, all! Awesome forum, and I'm thrilled to be here! I figure I'll just jump right in, hope no one minds. I've got a '92 F2, and want to swap the forks. I'm leaning toward the 2nd gen F3 fork (as well as the wheel, fender, and brakes) with RaceTech guts; but I'm seeing a lot of comments about losing the speedo if I go with '97-'98 parts. I'm curious, why is that? Isn't the speedo on the 2nd gen F3s cable-driven off the front hub like it is on earlier bikes? I'd appreciate anybody's input. Thanks!

I'm wanting to keep the F3 internals, just replace the chrome upper part. Mine are bent and I have some F2 forks lined up and don't want to replace the brakes and wheel

The speedo on F3's is driven by the transmission.

here's my question -

I have a 92 with the stock fork in it now, and a bought a set of 94 forks that I have all of the seals and racetech springs to rebuild.

I'm looking the 94 fork over and there's a little pitting/rust here and there on the uppers. My 92 uppers are clean. Can I swap the uppers on the forks so that I have the better uppers from my 92's and the internals of the 94's? I hear the lowers are identical, which seems odd when the seals are different part numbers.

The uppers I have on my 97 are from a 91 so I would assume that a 92 would fit a 94. Just take them apart and compare

Does anyone know where I can find more info. on this bit? The FSM doesn't go this deep.

Thanks in advance.

I have a 93 or 94, and the fork tubes are pretty screwed up, have changed the oil and dust seals twice but starts leaking again.
In India its very difficult to find spare for an imported bike.
there is a friend who has converted his F3 forks to 954 forks and he sold me off his F3 forks along with the tripple T's and stem which is very very good condition. Now the plan is to drops the complete upper sets into the existing legs of my F2.
Below is the pic of the existing upper side of the forks.
