From what I read, here are the better ones over the stock Dunlop. Only trouble is whether or not can find here:

Michelin Road Pilot 4
Pirelli Angel GT

"Added 150 miles to the tires today, nothing too major but a nice ride none the less. Stayed out of the twisties but I can already tell they have so much more grip than the stock Dunlops. Small bits of sand and dust had no effect that I could feel, where as the old tires would slip and slide everywhere.

I would highly recommend the Pirelli Angel GTs to anyone looking to switch up from the stock Dunlops."

"I went with a Michelin Road Pilot 4 and now up to just over 19,000kms (9,000km tyre life). Very little sign of wear compared to the Dunlop stock tyre. They grip really well in the cold and wet."
