E09 front is crap
I tried E09 Dakar front and rear on my bike ( DRZ400) and I wish to advise that on sand the E09 profile is too small to provide any flotation in softer sand. The hard side wall wont flex even a low pressures ( 8psi) and the knobs are very short.
It is fine on gravel roads/slab , slightly scary in mud and downright dangerous in sand. It just digs in and spits you off. My fractured leg has healed a year later!
The rear seems OK and fairly hard wearing.
