Nope, 5500rpm.
Triple, all the power and noise is mid range isn't it. IL4's sound like they are on idle at 5500rpm, they scream at the top end don't they.
Its an Arrow Titanium system.
Was shocked to say the least, was expecting around 104db myself, but 107, bloody nora
Muffs, yeah, popped down there at lunch and had the bloke test it.
