Yixing is 1.5 hours south of Nanjing, 1.5 hours northwest of Shanghai, 45 minutes west of Wuxi. Our retreat is west of there by about 30 minutes in the mountains but not mountains like you have there in Chengdu! Great riding at our retreat during the week. Weekends are OK if you avoid the tourist traps. I like Chengdu and go there for work sometimes. Looks like a wonderful place to ride. Hopefully, I will get to try out the F800GS there in the future!
