Are you talking about grand prix bikes?
They'll all be electric by 2035 anyway.

No what I mean is that UK goverment intends to ban all sale of new petrol cars by 2030 , bikes included but maybe 2035 in their case.
Petrol vehicles already on the road will be able to continue as before.
Many other countries will probably,or already have plans to do the same so bike manufacturers will almost certainly have withdrawn petrol bikes from their model ranges by then.(BTW Yamahas electric bike engine comes with what suspiciously looks like a oil filler cap and spin off oil filter,an electric motor with some sort of gear transmission maybe ? , or maybe just to keep it cool-ref.spontaneously combusting Teslas). ******
The big bike market is tiny compared to world wide bike sales anyway (which will increasingly be electric small bikes and scooters) so any contraction in the big petrol bike market would make any future development of new models economically unviable .
My point was that any petrol bikes that do remain available to buy in the early 2030`s will have become so emasculated by increasingly stringent emissions and rider safety regulations that for all the difference there is you may as well be riding an electric bike anyway.
****** Yes , Yamahas 350 KW motor , which looks the most suitable for installing in a motorcycle , due to it`s extremely compact size is definitely oil cooled,hence the filter.
One of these installed in a motorcycle would produce the equivalent of 470 bhp , although only available in short bursts , continued use of power of this scale would see a gradual fall off in performance and decimate battery range . Obviously battery capacity is limited on a bike compared to a car due to space available , although in automotive use one could be fitted directly to each wheel to give a combined output equivalent of nearly 1900 bhp , which I believe Yamaha have already done , although there would I guess be a weight penalty compared to a similar sized petrol car.
