Rake, Offset, Trail...Just another R1 fork swap

[iluvmyfz1]

When I did it, I had Ravenrider do the machine work to make the Gen 1 FZ1 stem work with 07-08 triple clamps. You can see the results in this thread. The way we got it to work was to make a sleeve that went between the stem and the lower clamp. The assembly was then pinned together to prevent the stem and/or sleeve from coming out of the clamp.

I forget who I sold that setup to but as far as I know it's still working.

I think I have that setup in a box somewhere......

He was talking about gen2 fz1 USD forks. which you can also use.

And its usually cheaper to just buy an r1 lower and re use the fz1 thats modified

Yeah i know and i was wondering because it uses the same inner cartridge.

About the FZ1 gen1 stem:
I would have to buy one, because i cant destroy mine.
We have TüV in Germany, every second year we have to show the bike and let them inspect it.
If the TüV guy isnt happy or had a bad day, R1 forks on a fazer is a no go.
So it is highly recomended to have a stock version in the basement.
Transfer for one day and back to R1.

This is also the reason i want to go with FZ1 gen2 upper yoke.
It looks so much NOT modified wich is a blessing in my case.

Maybe buy a gen1 stem is cheaper then letting the CNC work. This is really possible and a good option to keep in mind.

Gen2 oem forks, one fork does compression, the other fork does rebound, and they do it poorly. IMO

Okay guys project started.

Lower clamps of a 02/03 5pw R1: 100€ from the Netherlands
Upper is 2006 FZ1 2d1: 45€ from Italy

Both stunning looking parts no wear or damage, perfectly straight.

Tomorrow i get in contact withe the stem manufacturer.
They press out the old, measure, build the new one to press fit into place.

Next is ordering the bearings at AllBalls, and decide wich tubes(legs)
02/03 is pretty nice i think, keeping costs as low as poss. but still getting major improvemnts over the OEM forks.

Axle and Fender are not very expensive.
Would like to go the best possible parts like 07/08 but the wheel alone would maybe double up the budget, without brakes wich i imagine could be as expensive as the wheel. If not more.

I keep you updated

Can ATF be used instead of fork oil

[WileECoyote]

Is there a solid reason? Fork oil is cheap and comes in many different weights.

Can ATF be used instead of fork oil

It can it does have anti foaming buy you may not get the same results as you would with fork oil. ATF maybe to light of a oil depending how the bike will be ridden and your weight !
