On the Suzuki TL1000 web sight they rave about a 15t instead of a 16t.

I read on there that your speedo with be about 7% out. Think some body clever did thier maths.

Therefore if you speedo shows 100mph your real speed will be 93mph.

At 30mph on your speedo your real speed would be 27.9mph.

Also speedos are made to be acurate to within +or- 10%
Manufacturers tend to go on the side of safety all the time and be acurate or read over what you are doing.

The last 3 lines are from an old Top Gear program where the tested car speedo accuracy.

In the real world forget about it being out and treat it as correct and you will be on the safe side of being wrong.
