I have a bad shift solenoid in the gtp so 90 is all i have had it to.
150 plus in the mustang before the 410s, now she tops out in the 130s.
186 (speed limiter) on my 04 ninja 1000.
173 (speed limiter) on my 04 gsxr 600.
With all the laws they can throw at you plus being older and realizing the danger that a vehicle traveling that fast is to others I dont think I will push any of my toys that far again.
