Ok installed Ride 3 and gave it a go in VorpX.

Perfect world scale, full geometry tracks, great sense of speed, performed well with everything maxed out (3090)

AI riders looked like stuck on projections on track, control and immersion is difficult to grasp with a gamepad, the lighting at night and it's projection isn't VR fixed (like in project cars 3) You'll need your VR feet if going with full VR and head tracking.
Reasonably impressed with it, turning off the AI and taking a free ride around the nordschleife on a fireblade was rather thrilling, as much as doing the same in a lotus49 in a native track racer is in a native VR title.
The major problem is the control and immersion, it left me feeling much the same as pcars did in 2016 when i played it on the keyboard. If there were a handlebar controller and you somehow rigged it up to a standing bike, you'd be in the same kind of dreamland as sitting in a sim rig.
Perhaps if your more versed at bike games with thumb sticks (of which i am not) then you'll get more joy out it. Recommendable, but take the negatives in to consideration, the AI riders look pants (probably due to the lighting and shadowing) and the whole control thing.
Not the perfect VorpX experience, but not the worst either. Thanks for giving me a reason to try it though
There's a free demo that works with MX bikes in VR. fair warning though, it's very motion sickness intensive when you fall off.
