I have had many bikes in the past 36 yrs of riding.
Most recently M109r I thought I would never get another bike.
I miss the RUMBLE but this new bike is amazing, my 6 into 6 pipes on order.
I know it wont sound like the 9 but hopefully it will be sufficient

It may be me but the way my 9 was set up I dont think the F6b pulls as hard
