SOURCE: How fast
Contrary to what the speedometer might say (and GSXR 750 owners), a 2008 GSXR does not have the displacement to reach 180mph. A road test conducted in germany had a rider reach 181mph - or what said 181mph on the speedometer - but was actually clocked on radar going 173mph. 173mph is what a GSXR will reach at around 1200 feet altitude and 65 degrees fahrenheit. Depending on the altitude and temperature, you might have slight fluctuations. If you want to go 180mph+, just get a GSX1000R
