Yeah, of all tyres I've used on my CBR600RR, radial Shinkos have been most troublefree and long-lasting over 10k-miles; on my 3rd set now. As grippy as the Dunlop Q2s I had previously, but much longer lasting.
Balancing is important as well, especially if you go fast! Before mounting, I find actual heavy-spot on my wheel (all previous weights removed). Then I mark this spot (not always at valve-stem), and line up yellow-circle of new tyre to that spot. This lines up heavy spot on wheel with light spot of tyre and minimal balancing weights needed. If less than 10gm weights needed, I don't bother putting any weights on at all. I use
one of these eBay balancers. Verified balance after 1st time with one from
MotoGuild SF and it was spot-on.
