If you're just riding on the road you'd be crazy putting on these tyres. They'll never warm up properly and they'll likely give you less performance than the ones you've currently got on. If you want to upgrade to a better tyre, then a good sports touring tyre (Road Attack, Z6, BT 020) will give you all the performance you could wish for. And if you're that fast that you honestly need more, then a Pirelli Diablo would be hard to beat.
Don't believe all the hype, the real world is where it's at
