Another thing to bear in mind with lowering a bike is ground clearance and the stand. When I bought a lowered bike it took ages for me to work out why it was so hard to get the darn thing on the centre stand : : Just something to bear in mind if you are going the lowering route.

I'm sure some bikes are fine lowered but having had lots of different bikes I bought one unknowingly which had been lowered and it took several days to work out what was 'wrong'. It just felt odd and handled really badly. At the time my OH had exactly the same bike and I took his out to see if it was the same and couldnt believe the difference and why his cornered so much better...until we parked them side by side.
