I just put a set of mefo tires on. They seem like very good quality! On road they are great, especially compared to the 606's I've been running. Front tire hooks up just as well as the 606 off road. Rear works surprisingly well in grass(better than the 606!!) Lacks alittle in the mud, but what do you expect. So far its been great, about 700 miles on them, the tits are still on the front and rear. Hopfully I'll get the claimed milage out of them(14,000). I knew they were not a knobbie, but they are working better than I thought for a high mileage tire! Just thought I would pass on the info. I have tried many differant tires, and are not completely happy with any. And all have dissapointed me in mileage. http://www.klr650.com/MEFO%20Sport%20Tires.htm Thease tires are more agressive than they look in the photos! Rear tire has realy deep knobs, looks very long lasting. But on pavement this thing corners great!!! Can't say enough about on road handling(remember though I am comming off of knobbies) I am going to post some mud handling photos to show you how they work there also. Obviously hardpack they would work great. Its the slick stuff that always worries us. Front end still slides out on slick mud, defenatly is not a knobbie. But as I said before the front is about the same as the 606 off road, but alot better on road!
