Why Yamaha stopped the production of FZS Version 1?

The Yamaha FZS version 1.0 was surprisingly laid off from the Indian market, also cutting down other bikes like Fazer version 1.0 and Yamaha Crux. The move was made in order to promote the new products in the Yamaha lineup while FZ 16 has been kept on the list for some secret reason. Yamaha's blue core technology on the newer entries has made them class leading with excellent refinement and mind blowing efficiency figures. Currently only FZ 16 can be bought in the first generation and even it will be soon discontinued from the official lists of Yamaha motors.
