| Having now spoken to the guy selling them it appears they originally came off an ST and the fact they have the cush drive built in says they're more than likely the standard 5 spoke alloy wheels (badged Marchesini but made by Brembo(?)). This means they only weigh 1 LB less than the 3 spokes fitted to SS's. They also look different from the "genuine" lightweight Marchesinis.
As Jools says a track school will improve your riding, although the wheel was standing at £150 with no bidders, so you'd have trouble finding a decent school that cheaply.
As an aside apparently Motorrad (a German magazine) did a test fitting lightweight wheels to one end of the bike at a time. It turned out that the rear had the most noticeable effect. Can't see it myself and I only read it on the Interweb thingy so..... |
