Why do you want a 200/50? It will slow the bike down. That's why the don't offer that size readily.I was thinking of getting 200/50 rear and 120/70, but it seems that they only offer 190 width. So I was browsing thru the net and found this site http://4wheelonline.com/motorcycle/Motorcycle_Tires.106588. They are selling the exact spec that I need with a good price 200/50 for $176 and 120/70 for $106. What do you think guys is it worth it?
