my bike speedo reads 15-17 90% of the time... However.. I passed my supervisor today on base (just to be a smartass

) and he said he was traveling at 26 when I passed him, however my speedo read somewhere around 24.... so take it for what it is.. He told me he would laugh alot of the MAs gave me a ticket for speeding
Edit: I only covered maybe 20 feet passing him, so it was a pretty quick move around
