Hi,
I have had my bike for 2 years and been loving it, but last week the wire at the base of my speed sensor on the front wheel snapped and I don’t have a visible speed on my Speedo anymore. I have been looking online and cannot find any speed sensors that use the same 3 wire design and puck at the front.
Does anyone had any ideas as to alternatives I could buy or am I now just stuck without a speed reading?
Thanks

MotoGB (real Hyosung UK importer) wants ÂŁ200 for it.  Used ones on fleebay can be hit & miss unless the seller guarantees that it’s been verified (they rod the bike before stripping) . Hyosung is not making new ones for your carb model as they are moving on to the EFi 125cc starting with GV125-S (no news on new EFi GT125 yet but even then their speed sensor wont fit yours)
But I may be able to get you one rapidly for less , depends how urgent it is! Send us an email.
Otherwise I have a fully working used one from a donor bike (it will be on ebay around Thursday/Friday for purchase)
Hyosung’s wheels are unique to the GT , and the speedo sensor also acts as a big spacer.  Personally I have not tried other sensors front different bikes because I stock piled my own spares (Yes it failed on me too!)  and plus there is cameras everywhere , i dont trust a china speed sensor to tell me its 30mph when the wheel is rolling at 38mph and i get flashed!  I think OEM is best but have a spare copy yourself too!
If i ever discover and test a genuine japan suzuki speed sensor & fits on our wheels without needing calibration, I will make it known on this site!
Hope this helps ?

That’s a shame that they don’t make them anymore.
How much are you looking at selling for/ could you send me a link when you do put it up?
As I said I am currently without a Speedo and while I can use GPS, my problem is tracking miles

Send me an email for a sale quote now  (GPS on WazeApp is a good backup!)
