Based on what I've seen of the frames, the XP Pro (current 64" width, turbo 2cyl model) cage should fit a Turbo R (new 74" width, turbo 2ycl model). However, XP Pro cages won't be a direct fit for the Pro R (new 74" width, 4cyl model).
Good to see some confirmation. Hopefully Kevin will figure it out soon, maybe he'll have to take my Pro R as the guinea pig! 😉
