Sounds great to me ,dont know how it copares to termi on 749r.
It certainly dosnt have the base of my 890, but does seem to have a metallicy deep rasp much like the wsb bikes.
I feel a comparrison test at rocky comming on!
I think if you are looking to go no further than ive gone already then the 54mm system would be the best bet (£300 cheaper,and no fairing fitting problems) but with my passion for visiting John it had to be the 57mm jobby
