I can't speak with any authority but I believe Energica does refer to them by a different model year than the US.
Yep. I learned that from the TTSE forum. The 2012 TTSE in England is the 2013 model in the USA.
In England, if you buy in Dec of 2019 it is not possible to buy any 2020 model. But it will be called a 2020 model in the USA. They use the date purchased new instead of a model year. Perhaps it is that way throughout Europe. And perhaps a better idea.
Here in the USA it can get confusing at times.
For one example:
I have a 1984 Yamaha Venture. To buy parts, it is an 1984, 1983 parts often are different. But my 1984 Venture MUST be registered as a 1983. It has a frame date of "9/83". But a special federal tax started on larger foreign made bikes made in 1984. IIRC, it was to give Harley a much needed break back then when sales were very low. Since my 1984 Venture was made in 1983, it avoids that tax, so it must be registered as a 1983.
This Yamaha Venture of mine is often referred to as the "1983 and a half" Yamaha Venture.
