Last week I received my 130/80/17 E07 and mitas heavy duty tube. I wanted to try them after seeing the posts here at ADV. After receiving the rear I wish I had ordered the front at the same time, as now they are sold out of my size in just 1 week after receiving a new shipment from Mitas! Seems they have become very popular for MX1canada!
I plan to run my k60 with only 8000kms on the front now, the k60 rear was toast after 8000kms.
The E 07 is a 4 ply tire that is noticably stiffer than the K60, the K 60 says 3 ply on the side. I'll know more about the perfomance when I spoon these on in the spring.
O yea there is a wear strip down the middle which will provide some extra life near the end of the knobs life for anyone on an extented trip.
