I've done just under 5500 on my Diablo's on a GSXR600 which delivers power a little different to the SV. I'd say my front is good for another thousand possibly but the rear is squared off - less than 1mm tread in the middle but a good 3 on the edges. Even though they have been used on the track and twisties, alot of the riding was on A roads hence the squaring off. 8000 I can believe if you look after your tyres, 16K for the front would be exceptional. The 2 rears to a single front depends on lots of things, if you push the front on the twisities/track, or use a lot of hard front braking, it soon gets used. If you wheelie everywhere should last 100K
