• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

According to the '21 Operator's Guide (quote):
Ryker 600 and Ryker 900 (NON-Rally)
WEIGHT CAM POSITION
Up to 100 kg (220 lb) - driver alone (Factory setting): 1
More than 100 kg (220 lb) - including driver and cargo: 3
With a passenger: 5
If you ride often with a passenger, talk with your Can-Am On-Road dealer to determine if the purchase of a rear spring specially designed for riding with a passenger could be a good option for you.
(end quote)

For a more quantified approach: On the rear shock, put a small zip tie tightly around the piston rod. It needs to be very snug. Try not to scratch the rod. With the bike on solid level surface and no gear/passengers, slide the tie wrap all the way till it stops against the piston rod seal ring. Load up as anticipated including driver, passenger, beer, whatever you expect to want to carry. Go for a ride. Unass/unload the bike. Note how much the zip tie has moved from its starting position and contemplate this as the resulting stroke of the shock under all your load and specific road conditions. If it got close to bottoming out, you need to adjust. Most people I know use the rule of thumb that if the movement is (was) over half of the available rod length, they will adjust. Alternatively, you can run the test with just you on the bike to get a baseline for comparison to the fully loaded test. The resulting ride characteristics are also an additional, subjective factor. You can just leave the zip tie on there if you like. I like having it on there myself.
 
Unless they've changed in the most recent model year (I have a 2019), the rear spring doesn't hold much in real world applications once you start adding passengers and cargo. I've read others who added cargo racks that are making contact with the rear fender when bottoming out. I added the available 2up spring from Can-am, but have since upgraded to a custom rear aftermarket shock and spring from Elka. If you think the 2up spring would suffice, I'll gladly sell you mine! It's already mounted to the shock, less that 1k miles on it!
