Phil, measure the upper and lower tubes on your 45mm Zokes (if thats what you have). Both my 2010 and 2013 Gas Gas triples measure up the same. The forks swap from one bike to another easy as. Only difference is in the spacers and axle as the Sachs lug sits inwards further than the Marzocchi.

I'd love someone to confirm the 45mm measurements if they could.

I need to spend more time comparing the overall geometry of the 2010 chasis vs the 2013. I won't know how the extra trail feels until I've tried it. I don't think I'd want any more tip in or activity in the turns on the 2010, but the 2013 feels much less flighty and doesn't corner as well imo. It may like it.

All of my zooks and wp's where interchangeable in the triples.

I had a local tuner confirm some WP measure 54/60. What I'm thinking is that Gas Gas actually only runs a single triple clamp on all their bikes, and the various 45mm/48mm configurations all clamp on the same outer diameters.

I was looking at the KYB SSS dropping into the 2013 GG triples, I must have misunderstood your measurements in the early posts.

I have 2011 gasgas 45mm zoke triples
2011 race 48mm zokes
2011 Sachs 48mm
BRP upper triple clamp.
The uppers all interchange.

The lower 45mm and 48mm gasgas clamps are different size. Not just bored out. But bigger OD and ID

Thats the info I was looking for. Thanks roverhybrids.

Still looking into info regarding axles. Have a mate measuring up a 2013 CRF450R with 2012 YZ250F forks for me after the weekend. I also need to confirm that he used the Honda axle and wheel spacers. I know he went to an oversized disk with carrier, while I plan to use the stock Gas Gas disc (and will require a YZ250F 260mm carrier).

Center line of fork to center line of fork on both our bikes is 190mm.

I'll need to source some smaller ID wheel bearings in order to run on the 20mm axle. Measuring up spacers to center the wheel will be an easy task, but if I can get away with finding an OEM setup that slips on it'll be even easier.

I'd be thrilled if you can find an off the shelf solution. I'm about to service my 48mm and am curious what might be found.

I'm hoping you don't find what I did. I've just finished cleaning mine thoroughly, revalved them again, and will continue to ride on them. I expect the damaged one to continue to wear but would be stoked if it stopped. They don't feel too different in action when filled with fresh oil, but if you have them pulled down the good one slides much nicer. At least I still have some nice stacks for these forks. Now for the next 6 months to revolve around KYB revalving.

Honestly, first service, there was some crud in the oil. Second same. I'm dreading my third oil change at 135ish hours. I wonder if it is even worth picking up a set of bushings. Regardless, I'm going to ride them totally into the ground but it would be nice to know there is a nifty backup.

I'm very curious about your thoughts regarding the change in trail. I love the bike's slow speed handling, but if it was a little more stable at speed without knifing excessively in gnar I'd be thrilled.
