That is actually a clever move from Aprilia as it would turn their racing department into a commercial money earner too.
as much as we'd like to think Aprilia is doing us a favor by giving us access to their go-fast technology, it's ALL about the money.
Nicky Hayden decides to leave MotoGP and go to WSBK. He talks to Aprilia first - they have a fast bike that he could be instantly competitive at the front with. But Aprilia isn't even sure if they can be in WSBK, so Hayden goes with Honda. Honda's stable. Ten Kate can pay him an actual salary and American Honda can kick in sponsorship money.
Nobody thought it was weird that, after Guintoli wins the championship for Aprilia, they DON'T renew his contract? And Eugene Laverty, who was extremely competitive on their bike, is also sent packing?
The problem with successful riders is you have to pay them, oftentimes a lot.
Even Ducati ran into issues - they pulled official Ducati Corse support from WSBK when they hired Rossi. $15 million is a lot of money - you can run a team for a season in SBK....or pay the salary of the world's most famous racer. So not only did two years at Ducati ruin Rossi's streak of domination in MotoGP, it surely delayed the development of the Panigale as a competitive race bike.
Anyways, Aprilia Racing needs money to fund their MotoGP and WSBK efforts. I don't think any of their riders are getting a salary. With the end of the 250cc era, Aprilia no longer got the $100k per team, per season, for leasing out their 250cc two-stroke racing engines.
So, in a master stroke of genius/desperation....sell Aprilia Racing products and services to the public. Extremely wealthy trackday junkies will pay the big bucks to have real Aprilia race-prepped bikes under their pop-up tents next to their toy trailer and fancy RV.
