Decat Test Ride - KTM Duke 125 

It would be best to change the ecu map with powercommander but I haven't done it and it works like a charm. Just the noise is a bit too loud.

I don't think it makes it faster, but it feels more responsive to the throttle.

@@natasfresas If you decat your bike and not give it some backpressure on exhaust side, you will lose power. Your bike will work with lean mixture cause of easy flow exhaust. If you want performance increase you should do decat + mid pipe + performance exhaust + air filter AND REMAP. Or at least buy afr (fuel mixture) tunning module. How should I know these? I did same on my Duke390 :)

You're right on that, thought about buying a K&N air filter, but it costs like 50€ and not to talk about a programmable ECU, those are like 200€. Not the money I was willing to put on a 125 and risk a fine. (Although it was fun to ride, I removed the decat and left it stock. Also I recently sold the bike and got a Z650)

@@natasfresas yes unfortunately costs are amazing for these type of minor tunnings :( Hope you enjoy your new bike. I love z650 and planning to get one of it like you did.

@@natasfresas PLanning to get A2, is 650z enough and good after having duke?

Not really, it's just louder. I think it's 110, 125 with wind on favour and on the highway

It's probably the lambda, if it doesn't read the oxygen level it will give you an engine error, run a diagnostic. I can't help you much. Good luck!

@@natasfresas yeah it stalls if i not give it some gas

I haven't had any heat related issues with or without the catalytic converter

Petardea parecido a cuando lleva el escape cambiado solo. Lo único que suena exagerado, más fuerte, no del todo bonito

@@natasfresas esque voy sin dbkiller pero no petardea nada y era por saber si así petardearia

Que raro, debería hacer algunos pops al reducir marchas

Hi, it's an European 2019 model, it came with the TFT screen from factory

@@natasfresas so lucke man, i have the 250 duke 2021 and still have the old display. Happy new year bruv

I didn't change the ECU, it's stock. It probably would've been better to use a power commander to fine tune it but it's also okay like this.

@@natasfresas thanks for replay keep make videos i also have duke 125 its such a great bike good brakes and handling, also design is amazing

Thanks for your comment, I'm glad you liked my videos! The duke 125 is an awesome starter bike 😎

​@@natasfresasso the power isnt lower?

It's actually more power when you remove the catalyzer, maybe 1 or 2 HP more. The mivv exhaust alone gains 0,5hp according to the manufacturer tests

No, this was with an aftermarket exhaust, mivv m2. The stock one is super silent.

It's aftermarket, mivv m2
