    Yeah i know that its not a rocket ship. But i hope for little more throttle response and 1-3hp more

      If I wanted to go silly fast I'd take my ZXR out for a spin 🤣

        No disrespect meant from the start! But I’m guessing that you’re about 17 and haven’t ridden a great deal of bikes?
        Every 125 Has been restricted to about 12bhp since the late 80’s AFAIK. Any bike that is significantly above that has been de-restricted and/or tuned.
        You can unrestricted early dtr’s by ‘pinning’ the power valve open. This will give you higher bhp but will basically make the throttle an on/off button with terrible response.
        Later bikes I don’t know as much. You can unrestrict them and the variable power valve will still give you better low rev torque/response (I’m guessing that is what you mean by throttle response?)

        Do some reading up on deristricting your year model bike, then do some riding. Stop worrying about numbers bud, enjoy a wicked little bike for what it is, before yearning for more...

        @SpookDog I believe you could also show your License to Yamaha at time of purchase and they'd fit the YPVS for you. Hence why some came with the valves.

        The latter models were restricted in other ways and probably came with the valves fitted for emmissions.

          I did wonder where all the 3 wire servo’s came from. I heard that a 1000 exup had the same servo. Thought that was a 4stroke though.
          I love learning new shit!

          Did you mean the 5 wire were emission related? Dunno, I still think they are for improving bottom rev torque. Interesting though...

            Off topic. I saw the most beautiful bike ever. It was a Ducati with a ‘space frame’ of steel with about a 750-1000 v twin engine. 80’s looking. I never got a look at the numbers, never had any decals. Cafe racer, clip on looking dream boat!
            I’d really love to find out what it was...

                The consensus is a fully de-restricted - Pre 1999 DT125R (Light Generator design) , All the ECU's are unrestricted pre 1999/8 will make around at 18hp stock, only because they rev out to 10,500rpm or so.

                Keep it real

                      Different dyno's read differently and also manufacturers often claim at the crank not back wheel 😉

                                      Genuinely, Brits are so lazy, the fact you guys can just switch between both of the languages is incredible. And to be fair, your English is better than people I know. English is a frustrating language too! So hats off to you 😛
