Wheels were Brembo as standard (no Oz wheels on the SP), and the suspension was a more exotic version of the RSVRs that followed it, but sorry chaps, its never worth £12K. I had the opportunity to buy a minter less than two years ago with 6500 miles from new for £6750. It was genuine and mint, all present and correct. I bought an Edwards instead. The SP is fine if you ride very occasionally and want a slice of Aprilia exotica but it is not an everyday bike and cannot be run on a shoestring or set up properly by the novice. Also, they were not 150BHP (crank) out of the crate, more like 110BHP (rear wheel) but tuneable to 150BHP (they needed setting up). The other issue is that if say a head gasket went, erm...they're no longer available as pattern parts and one of the few genuine spare ones apparently sells for over £400 on it's own. Its a very specialised bike. Counter to that is if it is set up properly (and that means frame, suspension and engine) then it still hold's its own today as one of the finest handling bikes about. For me though, the Edwards (at a claimed 147BHP at the crank) comes plenty close enough. More low down grunt than the Gen 2, more power than the Gen 1 RSVR (which was 132BHP in 2003 trim) and more useable as an everyday machine without wetting yourself about spares including body panels etc.
