Have the clocks ever been replaced, and/or has a white dial kit been fitted?

If you're sure the clocks have not been messed with, whats the max speed on the speedo?  Check the gear on the end of your speedo cable (gearbox end)

120 or 160mph = red
140mph = white

Be careful though, the gear likes to fall off into the box!

its red mate as i have already replaced that cog that always drops in, they are probably original clocks on 200k, they have 120 on them cheers
