In wet conditions I find the E4 not convincing. The front covered 13,000 Km and the back needed replacing at 8,000Km. They where OK if a little vague in the wet. I've just had Conti Enduro's fitted and so far, summer conditions and no real rain, I like them alot. You seem to be able to crank the DR over alot more.
Bump start is quite simple.
No need to jump on seat or so. 20m to move should be enough. Fitting fine, not too large, no problems with tank venting. Reaches up to the bottom edge of my helmet and is rather slim. Both side cords ripped off at the first mild storm.
