There will be 17 models in 5 years by Yamaha. Source, well dig out the main Yamaha thread which is locked.
Now according to source what I am thinking:
There are 3 Ybr variants, now let's assume Yamaha launch 5x 125cc bikes and 5x 150cc bikes total 10 bikes right?
7 models are still to be launch in different CC categories. Off course there might be some scooties in the lineup but my guess is Yamaha will go for 250cc category as well.
BTW Fzr 150cc will be here in 2016 according to that source.
And read this post with a pinch of salt.
