I am loving the full Brock exhaust and ECU flash, I had both the 300 and 400 at the track this weekend that passed. NCBIKE. The 300 pulls very strong and I saw 118mph and 116mph consistently. The other 300 with just a slip on and ECU flash at NCBIKE in June was running consistently 109mph in the straight. I was in 6th gear and didn’t hit the rev limiter, so I could have squeezed a little more out.
Maybe I will keep this 300 a little longer!
