I'd look around for another set of clocks.

My DT200WR came with kmh clocks which I've swapped the speedo unit for one from a DT125X which are mph for £40 used

@mhbikesnbits sorry - think it looked local that's all

Where are you in the UK? Not near Nottingham are you?

@Minia glad to hear that you're sorted

@CalDT125 Great result - learnt something new today

@NINJA I'm not sure but I could have sworn that the X forks were shorter not longer but like anything in life I could well be wrong!

@AndyJay that would give you a 12.5 weight - I'd stick with stock unless the springs are too bouncy for you and some stiffer springs if you're larger than an average rider

You'll need that welding and then tapping as I think a 10mm hole would be too large for an 8mm helicoil to fit into securely.

If you remove the cylinder a local engineering place should be able to tig it up for you reasonably cheaply

@NINJA I thought that the R and RE had the same forks and only the X had the shorter ones to work with the SM wheels.

Bargain
