Speedometer fix?

[dougl]

With the older Rockets, I could have just adjusted my speedo difference with Tune ECU. I went with a 55 profile tire instead which brought me close enough.

My complaint with the Triumph speedo is... why does my speedo only track in KPH? Why not a dual MPH/KPH model like those sold in the States? Been down south of the border for the last 5 months and have had to use my phone on a Quad Lock as a speedo %^&*$%&!!

Tuneecu doesn’t have a speedo correction for the 2500cc Rockets.

This is an issue with nearly all vehicles, it is not just a Triumph or motorcycle issue. I understand that the speedo can be fixed to read accurately. The workshop Supervisor told me this, but he did say it was very expensive, I never asked how much.
I fit a 55 profile rear tyre and this brings the speedo to almost exact, I am only out by couple of km
