For some reason my 06 640 came with a bullseye located squarely on the left front and side of my tank.
It's pretty easy to spot - it says "Drop Here" encircled in red and white. In spite of throwing my body in front of my left-side-tipping-over bike to save yet another tank scrape (resulting in breaking of ribs, foot and wrist) the bike simply continues to go left and plop onto the tank at speed! Oh well - if I get these tank guards, I bet I'll never use 'em, cause that's how my life works.
So please add my name to the list of people looking for some protection!
