Dt 125r dyno

[Calum]

That number sounds about right to me.

[jonne123]

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

[Calum]

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

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

[jonne123]

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.

[Calum]

@jonne123 That's not stock though is it.

That's tuned.

[Calum]

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

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

[jonne123]

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

[Calum]

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]

I guess i have to buy another bike but how could some dynos get 24hp from small changes and another 13hp

[Calum]

@jonne123 TUNED!

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

[jonne123]

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

[Calum]

@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]

Shoot. What i need to do to get more power? I have the better head, giannelli exhaust, carbon reeds.

[Calum]

@jonne123 Probably about it unless you want a headache.

[jonne123]

What i need to do to get 25hp? And thats its grazy that yamaha wr 125x has higher tuning stage and more power tham my 2 stroke

[Calum]

@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]

Now im sad i shouldnt dynoed the thing
