I was thinking about that too then I did a test with the Busa ODO and the GPS ODO and they were DEAD ON. Ill try it out again today just to be 100% sure.

yep they tested this back in 2000

its strange...seems like suzuki planned for the speedo to read low...

My understanding is that it is very common in vehicles.
