The trick with getting some engine braking on a long fast downhill is to gently blip the throttle until the clutch engages again. If you get it just right, the shoes will be spinning fast enough to stay 'out' and engaged. They'll eventually disengage though, so this is a rinse and repeat. Better than getting brake fade!
The clutch won't disengage until it gets below it's engagement rpm so going downhill it will not disengage until , in my case, about 17 kph or 11 mph. If you stay above that threshold the transmission will stay in the highest gear. So some engine braking but not much.
On long slow downhill stretches I alternate between front and rear braking.
I have not tried blipping the throttle to get the CVT to "change down" as it increseses the speed and will then revert to the highest gear or the same as before.
If the OP wants a Vespa then he'll need a minimum of a 150 to get the same power as his previous TW200. If he wants to stay with Yamaha then an NMax
