With the advent of speeding intolerance by the French authorities {announced last month: link}, where even a slight excess of the speed limit is severely punished, you now need to ensure that your motorcycle's speedometer is accurate. Although speedometers are calibrated, they are not calibrated individually, so they will show deviations. Even two identical motorcycles can show different speeds, but usually it'll be a difference of 1 or 2 kph.
French motorcycle magazine Moto Revue  has published a very long list of most motorcycles out there, and their deviation in speeds shown on their speedometer. They tested the motorcycles at speeds of 50, 90, 110, 130 and 140 kph.
Most motorcycles show a higher speed than what you are truly riding, but there are some exceptions. Here are the motorcycles that show a TOO SLOW speed, so in other words, motorcycle were you really need to watch your speed.
These are the exceptions (only the too high ones): - Ducati Hypermotard 1100S (2007); Shows 110 but is really 112 kph
- Buell XB12X Ulysses (2008): Shows 130 for 131 kph
- Moto Guzzi Breva V750 (2004): Shows 50 for 54, 90 for 96, 110 for 115, 130 for 134 and 140 for 144 kph
- Moto Guzzi Griso 1100 (2006): Shows 50 for 52, 90 for 91 and 110 for 111 kph
- Suzuki AN 650 Burgman Executive (2004): Shows 110 for 116 kph
The Guzzi Breva is the one to watch out for, since you'll get fined at almost any speed. FYI, here are the ones that showed the lowest speed deviations:
