Chrome Exhaust Yamaha YBR125 2009
N.B This is not as original for the later injection YBR's but is fine for the earlier models.
The exhaust fits straight on to later models but there is no inlet for the breather pipe from the crankcase.
It is fine to use the exhaust without the breather or just use a bung to blank it off.
Your bike will run without any issues if you do this.
