DT125X Exhaust pipe de-restriction question

Spartan · DTR Senior Member

Hi Martyna, welcome.

I have a DTX with a full dep exhaust. A full tank of petrol costs me around £8 and gives me about 90-100 miles. But I do only use it at the weekends and tend to be abit throttle happy with it sometimes. Depending on it's purpose, if was going to be a commuter bike everyday i'm sure you would get some more MPG out of it.

Thanks for reply. So it's not so bad. Maybe I will de-restrict it.
Is the difference big between full dep and gutted stock exhaust?

gutted front pipe is the next best thing to a dep

So if my bike 'eats' 5 liters for 60 miles, if I gut the pipe it won't be a big difference?

Not to the fuel consumption, I can still get more than 60 mpg if I want to.. hand can be abit too much throttle happy though haha.

my aerox 21mm carb is well not econimal , prob do 60mg to a tank , i read dt can do 100mg to a tank, and thats not even going slow all the time .

I dont think thats too much the truth haha. Dont think it could do 100. Ive had 70 when I was commuting at the weekends.

So can you just tell me how much bigger it gets? It was 5l/60miles. Will it be around 7-8l or more?
Is there a big defference in acceleration between stock and gutted stock?
Cheers aww
