At those speeds, there's a big difference between indicated speed (what your speedo says) and actual speed (how fast you are actually going).
Bike speedometers are notorious for showing a higher speed than you are actually going (5%-10%)
I would not expect a stock r1 to go much faster than 160 (actual speed). If the speedo says 170, then you are probably actually doing between 157 and 162.
If it reads 180 (I've personally never heard of an R1 speedo reading 180), then you are actually doing between 162 and 171.
All that being said...... I still call BS on the yamaha 170 claim. I would suggest that anyone inclined to believe them should wait for 3rd party confirmation
Hmm, I could say the same thing for you, bro.Originally Posted by stay_up
