I sincerely hope I am wrong. the drive has always been to build one bike that can be sold around the world, and only modify that single design the absolute minimum to allow the maximum sales. All of this emissions stuff has come about from California, and now Europe following in the footsteps.
When the EU was formed, one of the goals was to reduce red tape and import restrictions BETWEEN THE MEMBER NATIONS. The entirety of Europe is a large market, probably on par with the US/Canada market in volume for motorcycles. Maybe less, but not by a whole lot. If the EU sets a requirement, it is economic suicide for a manufacturer to build something that cannot be sold there. The EU can (and does) limit competition from outside vendors by creation of limits which favor local manufacture. The term is barrier to (market) entry.
This is not unique to Europe, Asia does very similar things. Many, many countries require local content in items sold in their market, as a way to keep their money in their market.
Building old slow heavy and overpriced bikes in a captive market makes for uncompetitive machines. When Honda started selling reliable low priced fun bikes, it was a severe kick in the market to the old guard. The 600 cc sport bike owes it's existence to HD getting Regan to put a tariff on imports of motorcycles, 750cc and larger. If it hadn't been for that tariff, HD would have died/gone bankrupt, in the same way that Triumph, Norton, BSA and many others had gone under.
The big four Japanese responded by decreasing the size of the engines in their 750 bikes to 700 cc, and hunted for a way to make a bike that was exciting on a smaller lighter form. Selling bikes that are just as heavy and just as expensive with 80% of the power, is not something the market was really interested in. You could easily buy a Harley, if that was what you were after....
The Japanese home market had a lot of 400cc inline 4 sport bikes. When you bore one of those out to the maximum it can take, it comes in at roughly 600 cc. Sales exploded, and the vicious cycle of newer and better took off resulting in replacement models every couple of years throughout the '90s. Ever higher compression, and RPM limits meant those displacements could produce almost as much power as a 750 within a very few years.
Market driven product development, how ever stupid the decisions of the legislators involved is. I guarantee that if there were any way for the big players in motorcycles to avoid developing electric bikes, they would do so in a heartbeat.
