Finally got them together and on the bike. Rode a little. Very plush. Had to replace o rings on the free piston. Now to figure out the shock.
Thanks everyone for the help and info in this thread. And thanks to Jim at shock zone for figuring out the o ring deal.

I bought a set of SSS forks off a 2013 WR450, they have the 56mm upper clamping area but have forged 35mm offset axle lugs with the 3mm thick bottom sections. Was going to have them machined like Marty Moose but got to thinking. Does anyone know if you can swap the lower stancions with 35mm lugs to the uppers of a newer style SSS fork that have the correct diameter fork tubes? Basically mix and match 2 sets of forks to make one correct fork to mate up to a Beta?

I sure you could but getting the lugs off KYB forks are a bitch to get off.

Yes I've read that. I'm talking about disassembling 2 sets of SSS forks, one with the correct 35mm axle lugs needed and one set with the correct upper fork tubes to mount in the stock Beta clamps. Can you swap the lower chrome stancions (not removing the lugs) and install those into a set of upper tubes wth correct upper 54mm clamp area. The lower tubes are all 48mm just not sure if they are interchangeable to the upper tubes with 54mm upper clamping area.

I see what you are getting at. I would say sure as long as tube length is the same. I have mixed and matched a few to make one good set out of two.

Hello,
i am fitting SSS forks from YZ250F/06 to RR300/2017.
(i had them on previous bike, Yamaha WR, which is sold now)

Tubes are machined now to 54mm(enough material left there), i have YZ250f Axle. I need to do spacers.
My plan is to let it do little longer and then fill them home to exact length.

Can someone send me approximate length of the spacers ? /maybe from fork lug to seal is enough for me./
If i good understand, i should start with the brake side spacer first, to center the wheel between forks, then do opposite site ?

Many thanks.

I also am hoping someone out here knows which years Yamaha 450 SSS have the 35mm offset. I’m looking at 2010-2013, 450 forks and hoping they’re gonna work.
