    I dynoed the dt it produced 13hp full power. There is this streetbike with dt engine that produced 14hp on dyno. The dyno is diy one. It doesnt like for some reason big bikes with small mopeds it works quite good.

        How is it possible because it has atleast 23-24hp. And in youtube there is a videos of similar hp to manufacturers claims.

          @jonne123 What! They do not make 24 horse power out the factory.

          15 is what I'd expect from a fresh DTR motor.

            But why they have dynoed some 24hp? Thats some bullshit everyone sais that it has 24hp and it doesnt.

                Tuned? I'm sure it's possible. But not stock.

                  I have giannelli exhaust but even here says stock. How does yamaha have so shitty engines because every other 2 stroke 125cc 1990-2019 makes more power.

                    @jonne123 That's not stock though is it.

                    That's tuned.

                      It's not shitty, it's road going.

                      It's designed to be commuted on daily with virtually zero maintenance.

                        Reads original so full power? 24hp. Do they have regional differences?

                          There were a few differences depending on region. But 15 Hp is about what I'd expect to see out of a factory DTR.

                          A pipe will make a difference and a decent CDI.

                          The rest will be marginal gains.

                              @jonne123 TUNED!

                              What's so hard to understand about that? They've tuned their bikes.

                                What does tuning mean? Heres one with stock motor. Maybe pipe? https://youtu.be/bAzNrjtCfps

                                  @jonne123 It means it's not what it was out the factory.

                                  That DTR in the video is heavily modified. It doesn't even have an airbox.

                                          @jonne123 How is crazy?

                                          The DTR uses an engine designed in the 80s and wasn't changed in its entire lifetime.

                                          The WRX is a modern four stroke engine and you're comparing it against something made 30+ years ago.

                                          The two stroke engine hasn't been developed massively for a long time. Four strokes have come on leaps and bounds.
