thanks ChinaV,
besides since they look almost perfect for my tours (and they are asking 2000US$ - at least if i purchase 10pc) i might give one a try ...if i can find a way to get them registered. right now i am going after the ybr250 as per your suggestion. (22.800Y in chengdu) keep you up-dated
heiri
p.s. will meet chinabiker in vienna soon..
