Here in Asia there is a lot of restrictions and taxes on bigger CC bikes. Here in Japan anything over 250CC's require an expensive bi-annual inspection. In this regard, I think that a lot of performance enhancing parts will continue to to be developed for the bike. Rather spend $2000 on extra parts then spend that amount every two years for inspection, tax, etc.
On the other hand IMHO... this bike was developed to: A) Look Cool B) Be Economical
Having those two features satisfy 90% of the buyers here in Asia.
