While I see the new Sirrus with the new suspension as really cool, I am always worried about proprietary parts. We had a recent thread on this forum (don't feel like looking for it) asking if regular Sirrus could be upgraded to this new suspension.

Looking at the schematics of this suspension, it involves replacing not just the headset, but the fork is a specific fork to the new suspension. Meaning to me, that you can't just change out one part for various upgrades with out changing the whole system.

Most likely not a big deal for anyone really wanting these bikes. But just food for thought if something breaks in the future and well, suspension does wear out and possibly break.

The fork suspensions are easily changed out for a better suspension or non suspension forks in the future.
