  1. SXS 2 stroke cylinder kits(125)

    General Discussion
    Hello from Colorado....figured I would ask you fellas, info seems scarce in the USA. Are these kits worth the expense? My bike is ported, head work, GET CDI, etc. Curious how this set up works versus modded stock stuff. Thanks a bunch.

    General Discussion
    Morning, Had a bad week in terms of bikes this week, my commuter (Duke 125 ’11) broke down on Friday, wiring issue, bike lost all power when at anything other than full lock to the right. Managed to fix that by running a bypass. This will eventually need sorting, it seems to be a break in one...
  11. What is this? (Duke 125)

    Supermoto
    My dad bought me a Duke from an auction house, where it got sold by an insurance company due to the bike being stolen and the costs being too high for the company to pay. So we bought all the parts needed, even a wiring harness. Now i've attached all of the parts and the Duke is working as...
  12. Stupid ambitious Turbo 125 DUKE

    General Discussion
    I know what you're thinking why not buy a cheaper bigger bike and get a better resale on your DUKE 125? But I'm an engineer so I can't resist :P First off I was thinking of buying a used small diesel turbo. Then disassembling, removing the turbine. I would then be able to power the shaft and...
  13. KTM Duke 125 - Coolant level

    General Discussion
    I think my bike has a small coolant leak. I often see drops of green coolant at the radiator connector. I tried checking the level today and I couldn't see the line of coolant between the minimum or maximum. Which would indicate very low coolant right? Yet when I open the filling cap it's full...
  14. Rear Brake caliper removal KTM DUKE125?

    Adventure
    Hey there, I'm a winter rider and as a result my brakes get coated in rock salt etc and tend to stick. I want to remove the rear caliper to give it a clean but I can't find any obvious bolts to remove. I'm not sure if it's a bit different because it's fully floating. :confused: Much appreciated...

  17. Is the KTM DUKE 125 Limted to 62mph 100km/h?

    General Discussion
    I bought a 125 2nd hand off a learner, so I am unsure if his has been restricted in anyway. I have a full car and bike licence so I don't need to worry about the 11kW EU limit. The bike gets to 63mph then jolts like the fuel has been cut, falling back to 62mph. I think it's no coincidence that...
