I'm looking at putting a new speedo on my dual sport converted 99 XR400. I currently have a analog speedo from an older XR250 and am looking at getting a more modern digital backlit version. I am leaning towards the Trail Tech brand but don't know which of the 3 versions to choose from Endurance, Vector or Vapour. I've read that the versions with the tach don't work so well. Anyone have a opinions or experiences with these?
