Might be the difference in the power characteristics of an electric motor vs. a gasoline engine. Tires have been built around gas engines for decades. Electric motorcycles are relatively new. I suspect once we start seeing more and more electrics on the road, the tire manufacturers will find it profitable enough to design tires specifically for electric bikes.
Clutching and shifting introduce little "shocks" to the tire carcass... something your (and eventually OUR) Zeros never experience. I suspect the same goes for my CVT-driven scooter, as I go through front tires on that faster than rears too.
Yeah, I thought about that with a buddy, but I font thing that is the case.
Yet, the absolute miles on the front looks like its going to be poor.
The Zero is relatively light compared to other sport bikes and I'm only 160 lb myself.
Maybe a wider tire front tire with more rubber would be good and you could replace the tires in a set.
I know on bicycles, the front tire last at least twice as long. I usually rotate them.
