Are Yamaha YBR125 exhausts Interchangeable


Recommended Posts

Earlier YBR125 had a carb (upto about 2009 I think)

Later ones have fuel injection. The fuel injection ones have a Lambda sensor in the exhaust.

So unfortuantely although they will bolt on, you would not then have a lambda sensor, preventing the fuel injection system working correctly .

Check where the sensor is bolted into the original pipe. If you can drill the replacement pipe in the position and weld a nut with the right thread into that position you may be able to adapt the older pipe to take a sensor.

Not always easy to weld bike exhausts though if you have got the right kit. With it off the bike you can always take it to a workshop and let them do it.
