Anyone know if I can get a 650b into a 2011 Rockshox Sid RLT Ti?

I have a 2012 Revelation XX and can just squeak a 2.25 RacingRalph into that. My 2.3 NeoMoto and 2.1 Nevegal have more clearance than the Ralph.

Anyway if the arch clearance in the Sid is the same as the Revelation I may be able to squeeze it. Thanks in advance for any answer.
