My dealer let me ride a 675 today with a Micron slip-on. OMFG! I have never seen such a HUGE increase in power on a bike from just a slip on. The mech recommended the standard tune, no need for any downloads and even just guning the throttle in neutral, it`s easy to see how much more responsive the engine is. On the road it`s a sensation, I just wish I could get one on the dyno to give you some hard facts on the HP. It`s way quicker than the Akrapovic and Arrow full systems and 3.5kg lighter than the standard. I`m starting to save up for one...
