It's time to put new rubber on my 07 XR650L. I ride 90% on the pavement and hop on the trails from time to time. I'm kinda liking the D606 Dual Sport tire but when I size it up at Rockymountain's site it calls for a 120/90x18 but also gives option for a 130. This is a wider tire correct? And if so has anyone tried a wider rear tire, will this one fit? Any suggestions for a better tire or even somewhere cheaper than r.m.atv/mc?
