Question for Erik regarding Track CVT

[Throttlepansy]

..I test rode an Aprilia Mana 850 the other day, more out of interest in the CVT gearbox, and very impressed I was too. The dealer mentioned that the CVT belt required replacing every 20K miles. I was wondering whether 1. the belt used on the Track 800 was reinforced polymer or metal (as in car CVTs), & 2. what the approximate lifespan would be. The cost of the belt on the Mana was ~£90, BTW.....
