ok ok before you all go chomping away at the bit about this thread already being out there, lets calm down. My best friend and i both own '07 R1's and his is stock and mine has just aftermarket GYTR exhaust slip ons. we have done our share of speeding when no one is around and always wanted to see what the bike could do. well we grew some balls this weekend and decided to open them up wide open on a straight road that no one drives on. We did our first run and my best friend said he hit 186mph on his, but i hit 189mph on mine. We thought this was because i had aftermarket exhaust, so we went back to check this theory and ran them wide open again. this time he said that he hit 189mph also and i had done the same. We did this 7 more times and held them at 189 for about 30 seconds at a time trying to touch 190 but never did. they always just read 189. My other friend mentioned that the reason they wont read faster is because the speedometers digital is set up to max at 189mph. is this true?
