Dt 125r dyno

@jonne123 170KMH is absolutely pushing it.
My brother has a mito and we were going down some private road and he said the speedo read 120MPH. I said, funny that mine read 90
But his was standard with an exhaust and 28mm carb.
My RS will touch that sort of speed but it has every mod conceivable on it. But you could touch that speed with a light rider.

I don't know, why don't you Google it.
The TZR wasn't anything special, so I'd imagine about the same.
If you absolutely must have the most demanding HP bikes then go for the Italian bikes. Aprilia/Cagiva or look for the absurdly rare and Overpriced Japanese bikes.
The TZR RR SP or the Honda NSR RR.

@jonne123 You literally don't understand do you?
Why does power = better?
That's not what the DTR was about. It's got nothing to do with power. It's a road going bike for learner legal. The requirement for that was 11Kw. It makes 11Kw on the nose. As does the WRX and every other 125 available today.
Power != Better!
The DTR is not a competition bike, the YZ is. And the YZ 125 makes like 30+ hp. it's got nothing to do with power so why do you keep harping on about power.
The competition for the Yamaha were bikes like
Suzuki TS125
Kawasaki KMX 125
And it was competitively marketed and priced against those accordingly.
Stop equating power to better.

One more question why did they restrict the newer dt is they didnt have too much power 11kw
@jonne123 The dyno doesnt seem accurate if it made 14hp with the exhaust, better head, reeds dont really increase hp numbers more feel and throttle response. But id say 14hp from that seems off. But like calum has been saying, you wont make competition dirtbike style numbers. They go 5 hours and then you change the oil, air filter and the piston is like every 40 hours. Like calum said the dtr is the opposite, its not meant to win you some dirtbike race rather made to be a reliable commuter bike that has the possibilty of going offroading.
However, first learn the difference between torque and horsepower, you can have a bike with loads of torque but not that much horsepower, or the otherway around.
Secondly learn twostrokes in general, how they work, how you tune them etc, theres literally an endless amount of stuff you can do to your bike if you have the skill and knowledge to do it, but you barely knew what calum meant by "tuning".Learn the basics first and stop fixating yourself on numbers and other bikes.
If high hp numbers is what u find important, then sell the dtr and get a yz or what calum mentioned above -

Sorry to intervene but a bone stock DTR can and will make 23hp?
(I have a dyno printout to prove it but once again Iām on my phone and canāt upload it)
However and this is a BIG however... I honestly believe that there where only ever 2 models of DTR capable of producing that figure from factory and without modification.The legendary fast boi UK 89 model and the French 97-98 4BL that came with the rare 3nc-20 CDI. (however even this model came with a 3BN head so could be argued that its ārestrictedā or generally not reaching its full potential.)
Now I could be wrong, but every other model bike even regardless of area code that Iāve seen has had some kind of ārestrictionā or something thatās hinder its performance more then those other two bikes.
However, Callumās right about quite a few things. Firstly, remind yourself what your machine was designed for, itās a steep learning curve for some of us me. Your DTR, just like mine, was never designed to be sending triples whilst waving a Ronnie Mac flag mid air. It was however designed to be bullet proof, see 14k on a set of rings and be as happy taking you to the shops as it is with some hooligan on it popping wheelies and blasting through some woods. The moment you realise that is the moment youāll gain a whole new level of appreciation for the very capable little deee teee arrrr.
Secondly another thing I had to learn is a two stroke is only ever as good as itās last/current owner and with near enough all our bikes cracking on 20+ years old unless youāre lucky enough to own a very well preserved French bike or someoneās build you may as well just assume it has 15hp as you will never know what all of the bikes previous owners have done to it

im thinking of buying zeeltronic and then for dyno adjustment. "rather slow bike with good tune than fast bike with bad tune"
