Nice this yellow Tiger ....
By accident I have the same colour
About the tunes ; I don't think there will change a lot by just get another one and another one and......
Every tune has some difference feelings , but if you really want a change you'll have to do things with the Tiger itself.
Air box modification , different exhaust are the main parts bringing a different bike.
But , I must ad mid it is nice to try out a lot .
So , just think about it.
