A CVT cools itself by air drawn in through the forward rubber tube (positioned in a clean air space within the bodywork) by the action of the spinning variator fan blades, and this heated air is forced out through the two vents in the belt cover of our Kymcos. The forward motion of the scooter through the air helps to suck the air from the vents.(just an assumption - science to support that probably exists)
Some scooters have additional air intake openings directly over the variator fan. Some of these intake vents directly over the variator have filters to catch debris (usually grass like stuff) , some do not.
But all seem to rely on the forced=air action of the variator fan to move the air along to the exit vents for internal cooling.
If you do not ride in rain, or through farm fields - you might explore the various 'open CVT covers' for the ultimate in cooling.
Sorry, I know you prefer proof rather than opinions.
I can't offer anymore proof than that Kymco has made millions of scooters - and have a pretty good handle on the science of CVTs.
If I saw a white paper exposing that Kymco Inc. purposely builds extra heat into their scooters to increase their belt sales - then I'd get on board with a need for 'correcting' the way Kymco vents their belt covers.

I actually see it this way - if the Agility CVT cooling system was such a “perfect” design, why would other manufacturers have add-ons like additional air intake openings directly over the variator fan ? Surely they would not bother to have such additional add-ons if it it does not make any diffidence in cooling CVT components on their scooters ?
That is just one example. I am quite sure such an add-on would improve cooling on the Agility CVT components as well.
Other manufacturers of more expensive scooters like Yamaha, Vespa, Suzuki, Piagio, etc. have other add-ons which Kymco models don’t have - add-ons like engine oil filters, rear disc brakes, cooling fins on bigger oil sumps, ABS brakes, etc. etc.
Again - if the Agilty was such a perfect design, why did other manufacturers bother to have such designs on their scooters ?
The Agilty’s are obviously a very good design - but I do not think for one second it is a “perfect” design. If it was so “perfect” , I think other manufacturers of high quility scooters would never bother to install add-ons which actually make their scooters more expensive.
Again - the Agility’s are a good design and it is good quality. I am not bashing the Agility’s at all - but I think we got what we paid for. Other high quality similar sized, or even smaller scooters have add-ons which could easily make a positive difference on the Agility.
