2021+ Yamaha WR450F - How to change wheel size for speedo (Grey Wire Mod)

Remove the clocks from the bike, then remove the metal bracket from the rear of the speedo. Remove the rubber plug and behind it should be a grey wire loop. Snip the loop and tape the ends off , then reassemble. You should have access to the tyre diameter adjustment setting on the clocks now.

I just tried this on my 2021 WR450f Aussie Edition Wow this actually works!! exactly how he says in the video, I don’t know how he worked it out but great job buddy. I was very sceptical about doing this but had to try it, I only fitted supermoto wheels last week and the Speedo was about 20klms out, now it’s correct again . Just want to thank this bloke again as no one else knew anything about it including Yamaha themselves so bigs thumbs up to you mate👍 Cheers

Do you know if this works for the 2020 model? ive been trying to find out since i brought the bike... Great video 👍👍👍

You are the man!!! 😂

But where is the speedo located on the bike? By changing the wheel doesn’t remove the speedo?

[@t0mmyP1cklez]

There’s a disc that goes under rotor and the axle goes through

Is you have fitted an ignition with key will it effect it if I cut that wire?

[@1972butchy]

Hiya it’s a 50mm long looped wire so pretty sure it has nothing to do with the grey ignition wire
