We've had our new 950 Sport for a couple weeks and love it.  Still in the break-in process but can't wait to really open it up soon.
My one disappointment so far is the availability of cage mounted accessories, specifically a spare tire mount.  There are generic ones but nothing I've found that's made for the 950 Sport bar design.  I'm hoping that the aftermarket just needs to catch up, but gees the 2023s have been out for a year now! 

How long has it taken for accessories like that to come available on previous year models?

Sometimes.. never but it took about three years for gen-1 accessories to start being available. It think its pure numbers and demand. SuperATV usually leads pack on that kind of stuff though. Drop them a line and express your interest.

I am finding items through kemi-moto. Also read certain can-ams use the same pro fit cage and so far their fitting on my 950 trail.
