    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 Probably about it unless you want a headache.

                        @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.

                            @jonne123 To get 25hp out of the stock DTR motor? I wouldn't even know. Port the barrel, increase the compression ratio, correct the squish band. Widen the exhaust port. Use an aftermarket ignition system. Use an underslung exhaust. bigger carb, uprate the air intake. Lighten the flywheel.

                                @jonne123 Not really, that sort of power at the wheel is good. And is still faster than the WRX. The WRX will be making that power for a very short time at the upper range, where as the DTR produces max power at 7K and revs to 12k.

                                The two stroke engine produces more power end of. Then it's just a case of how you tune it as to where that power is made.

                                My RS easily trumps my DT for power. But you really have to be in the powerband to use it. The DTR I can ride at low RPMs happily.

                                    That's a motorcross bike! You can't compare a full blown motorcross bike designed to last 40hrs of use to a bike that is designed to last 4000hrs!

                                        Speed and power are not the same. Throw the DTR off a cliff and the top speed is going to be quite high.

                                          I understand. Is it like 120?
