I had Mitas E-07's fitted to my WeeStrom on Tuesday but not the Dakar version which has a 4th ply for "a more rigid carcass and greater puncture resistance".
I took them straight out for 120kms to bed them in. Yesterday I checked the pressures and went on one of my favourite 350km loops which has 10% motorway, 20% dirt and 70% sometimes very rough and narrow back sealed roads.
On seal the E-07's are at least as good as the Karoo 3's showing neutral handling and no tendency at all to wander on patches or track along seams in the seal. I could even brake into corners with no tendency to stand up. One corner caught me out and I was so impressed I deliberately tried it a few more times for fun. The K3 is also good but not as neutral as the E-07. I have found that the K3 is very nervous until bedded in, whereas the E-07 is not.
On dirt the front E-07 is less susceptible to small bumps and ripples or even hitting stones on hardpack. Definitely less impact/vibration through the bars - perhaps the 3 ply vs. 4 ply?
The E-07 was also superior on loose surfaces, but only just. I liked the K3 as they were so much more confidence inspiring everywhere than the terrible OEM Trail Wings but the E-07's are even better still. I rode up a very steep and rutted hard pack dirt road with a covering of dirt and stones and neither end ever slipped. https://www.youtube.com/watch?v=h9ru...ature=youtu.be
Karoo's = 8, E-07's = 9.
I did not drag a peg on the seal but I would think that the Karoo 3 should be better here as the E-07's outside tread is knobbly like which is no doubt why they are better in deep dirt/gravel. However you can still punt your V-strom down any winding road at a very respectable pace without having to worry about the patches or poor surface that would have most R1 pilots easing off. I have yet to wear in the very outside knobs even after some spirited riding but 50 years in the saddle has shown me that those who ride 10/10ths don't do so for more than a year or two.
The biggest advantage to me though is the silence of the E-07's. Those that think they are noisey should try a K3 front as it fair howls at 60-80km/hr – just where you spend most of your time around town.
Seal – Pretty much equal but a peg dragger might find the K3 preferable as the K3 has more rubber on the road at full lean.
Dirt - The E-07 is a nose ahead for its better manners in deeper loose surfaces.
I have yet to try them in the wet..
I chose E-07's after reading that they give better mileage than the K3. So far they seem to be at least as good everywhere and cheaper, so to last longer is now a bonus.
