dropped my forks about 1/2" through the tripples and the bike will turn alow quicker without messing to much with the geometry. get some racing rearsets they push your legs up and back slightly pushing your top half forwards more and change of tyres switch to something like the michelin cup v profile it turns on quicker due to the v profile which gives better contact area in the corners.

only done this on a track bike so dont know how it would be on the streets i found the bike to be fast enough on the streets, although my riding style is erm different to most racers.
