Good info in this thread. I rode into work today in the rain - nice back roads - about 12 miles or so. I'm new to the sport. I bought my 2007 Agility 125 last Thursday. It is totally stock, including the tires. I think the stock tires are decent, but I have nothing to compare them to. Since they feel safe, even in the rain, and since the bike has only 3,000k on it, I think I will keep them for a while. I will be curious to hear how the various tires handle at speeds over 40 mph. My bike feels stable at 50, but I must say I would be even happier if it would be the next level more stable at such speeds.
