I have 1 winter and 2,500 miles on my T660ST and I'm very pleased with the performance, even stepping down from my 03 ZR800. The only disappointment that I have is the lack of top end. With the amount of torque it has coming up through the lower end I can't beleave there is no way of improving the top end. Has anyone made any proven mods to the top end speed ie:gearing. I am only getting 85-87 out of mine.
