And more the VNAs point I cant see it wiping the engine out completely. It'll just mean more investment will be needed into the development of said engine to make it fit the mold thus increasing costs to us....... definitely not cool 👎
I suppose there’s pros and cons.
It’s gonna be interesting to see how the car and bike markets evolve over the next few years.
2020 is going to see far greater choice in the electric car market.
Small 125cc bikes and mopeds might turn to batteries.
For bigger bikes,ie longer distances I don’t see electric working well yet.
What we are already seeing, and going to see more of, is variable valve timing. I’d say that’s a good thing. I was well impressed by the R1250R I tested. Just a shame I can’t get my hands on one right now, that is unless I pay for endless pointless options.
Turbos and superchargers. We are going to see more of these.

You might think that a piece of EU legislation is relevant only on that continent, but European emission rules are fast becoming the closest thing we have to a worldwide standard. Massive international bike markets including India and China also base their legislation on Europe’s emissions limits, and Japan also aligned itself with Euro 4 back in 2017.
It is not just in the automotive sector that EU legislation is becoming global. EU legislation and standards are fast becoming global standards across many sectors.
The UK has influenced and shaped these EU/Global standards. Soon we will be left with no influence whatsoever with respect to new legislation/standards but will have choice but to comply.
Politics over.
The issue apparently for air cooled engines is temperature stability.
