That is an interesting looking front end on that bike, but I'm not so sure about all the rest built into the tupperware behind that!!  And seriously, unless you like a crap ride, worse handling, and a bunch of computer problems messing up with your riding and causing things like Limp Home mode &/or VSS errors et al to crop up at random, then I'd STRONGLY recommend that you DO NOT switch to 16" rims!! 
Because of all the sensors & the VSS Suite/the Nanny, which is really one of the better Traction & Stability suites out there, these Spyders of ours really don't have a great deal of tolerance for changing the wheels on just one end to different sized wheels &/or making largeish rolling diameter variations from what the computers expect; so if you increase your front rim size to 16", then you'd need to run an even lower profile tire than OEM or you'll mess up the rolling diameter relationship between the front and the rear tires; &/or you'd also need to change the rear rim &/or tire size too, only there really isn't all that much scope to change anything much about the rims & tires back there!! 
Besides, if you do mess with the front/rear rolling diameter relationship too much, then you WILL have errors and quite likely bike/ride stopping computer errors cropping up! And even if you do run lower profile tires up front on the bigger rims to avoid messing with the rolling diameter relationship front to rear & the consequent computer errors, then instead you'll screw with the ride and handling, making it a lot harsher than it already is due to the even lower profile tires and less tolerance built into the tire/suspension set-up; loading up the suspension more in areas where it barely copes already; and you'll basically be compromising your Spyder's comfort, handling, and safety all for the sake of those 16" rims!! 
But it's your Spyder, and if you're into that type of pain, then you certainly can do what you will with it - I'm just pointing out the likely drawbacks!

Thanks for the good point. 
I'm currently trying out some interesting research. Currently, my CAN-AM RT 2020 front tires are 165/60R15 and my rear tires are 215/65R15.
With this setting, the number of rotations at the front is 550 and the number of rotations at the rear is 482, which is a difference of 68 rotations between the front and back. So far, there have been no VSS-like errors.
The 16-inch wheel tire currently ordered is 195/45R16. The rear tire was ordered as 215/60R15. In this case, the number of rotations of the front tires is 547, and the number of rotations of the rear tires is 498. The difference in number of rotations between front and back was around 49.
This is a lower rotation number than the currently installed tires. The number of rotations of the STOCK can-am spyder tire is 556-526=30. I think it will stabilize.
In terms of weight, including the forged 16-inch wheel and hub space, the weight was the same as the original wheel.
I hope it succeeds... hahaha

Yes, the rotations may be different, but because of tire size limitations there are no combinations of sizes that will upset the NANNY ..... About the 16" wheels I agree with Peter 110%, IMHO the size of the tires can make a HUGE difference in the ride comfort .... tires are part of the suspension system ....and the lower the ASPECT ratio THE HARSHER THE RIDE .... If your Spyder was used for RACING purposes only, absolute performance would be the goal .... also, IMHO there are no shock/spring ratio's that will make those tires comfortable .... good luck ....Mike

I have 16 inch front wheels and I love them. They ride great, handle great, and have no VSS issues.

So apart from all the hub & track width etc concerns, you can't just stick any 16" rim/tire combo up front; you will be restricted to running something that's either pretty low profile &/or very likely fairly narrow too, which might be doable, but isn't necessarily all that good for traction, ride, & handling; even if you are prepared to accept or ignore the changes/compromises that will come with running significantly different sized rims & tires. 
Plus, the lower the profile &/or the greater the change in size/width/rolling diameter/revs per mile you make by choosing different rims &/or tires on either end, the more you risk compromising the traction, ride, and handling of your Spyder as well as the longevity and compliance of your suspension, cos as has been mentioned earlier, the tires are an integral part of the suspension and how that works/how long it lasts; as well as being a major contributor to the comfort, ride, and handling of your bike! You can't escape any of that, and while it's your choice as to what tires you put on your bike etc. the bigger the change you make, the bigger the compromise and the bigger the risks you face!

I have 16 inch PPA wheels. Not sure they are available anymore. The tires are Achilles ATR-K 165/50-R16. Absolutely no issues. I have 4 different sets of wheels for my RT and run the 16's because I like the ride and handling the best.
