As i have driven the Zero SR 2015 on two occasions i can tell that the handling is very different.
Until now i have just driven in normal mode ( i also have sport Mode because i ordered it with the Corsa Kit(OZ Racing Wheels, Sport Map, Tech Seat, Carbon Kit and Fast Charging) i can only tell that the handling is great because you can really control the acceleration as if the bike is a part of you and the recuperation braking is perfectly setup on this bike it is not too hard and not too soft it is softer that the recuperation braking in my tesla but that is a good thing.
One of the many things to love except the look is the turbine sound that really gets startet at about 20 km/h+ so at about 15m/h+ it really makes you addicted to this bike and the acceleration is a total different dimension compared to the zero sr and you feel much more confident on this bike then on the zero sr.
I came from an Yamaha FZ 6N and sold it because it wasnt accelerating as good or better than my tesla and the running cost were much higher here in germany (we also pay like 5-10 times what you guys pay for electricity too but it still is cheaper that taxes insurance and gas bills for regular cars or bikes).
i bought the bike for my birthday as i turned 31 (last years birthday present was the tesla p85d).
Unfortunately i did not have the chance to drive that much and when i drove it was 5-10 °C and until now the weather here is terrible but i will write a lot when the next season starts (also bought the bike to drive less with the tesla(drove over 16.000 km in the first 9 months) and i can charge for free near my work place with the short charging CCS system of the ego). i plan to drive up to 15.000 km with the ego per year and i dont have it as some sort of collectors item as i only own those 2 vehicles as it is pretty expensive to own more and we dont have that cheap prices on land here so i dont even have a garage as i live in a bigger city ;-)
But you guys will read more from me -> if any question may rise just feel free to answer and yes the software language can be changed from italian to english :-) helps a lot
