I saw a video 14T front sprocket made the 390 .28 seconds quicker to 60mph. Quick throttle seems to be a nice edition. Rapid bike ECU claims 44 rwhp and better low end with stock set up. Open air box and full exhaust systems add power .
Most people don't have a dyno handy. What I am curious about is how much quicker same rider. Like I hit 5.3 0 to 60 stock now 4.7 as an example.
