Electric systems are so much more efficient, there's no way we can avoid this...but I would hope the legislation only pushes for city centre use of them in the long term. Getting rid of all emissions in city centres is important. But I still want the choice away from that.
BMW, racing a S1000RR derived bike would be intriguing to watch especially at the TT. I'd be interested to know how many other of the big manufacturers are already doing similar development work.
The end for the petrol engine is not nigh, but it's certainly going to have to up its game. I'd love to see a "torque fill" hybrid system on a bike ala the P1.
