I don't know of anyone that has done this on their Trophy.

If you remove it prior to the MOT, expect it to FAIL the Test,
as it is a legally required component of the engine's Emissions system.

What are the advertised benefits of doing this ?

thanks for the reply coconut.
it says better midrange and smoother power delivery as I corrects the dip in the fueling to account for the emissions test.

Hmmm ...  :084:

I can’t recall ANY Member, Worldwide, saying they have a problem
with the Mid-Range or the Power delivery not being smooth.

Sounds to me like the words of someone trying to sell their product,
for no real gain, and that could have potential problems !

Removing the O2 Sensor and fitting an adapter to “fool” the ECU
would not be strictly “legal”, and it may void your Insurance or result
in an increased Premium as most Insurance companies require to be
notified of any such modifications, not to mention the possibility
of increased pollution to the environment !

Cheers  :821:

Disconnecting, removing or bypassing the O2 (Lambda) sensor will throw up a code unless you fit a emulation plug in it's place or disable the input in the ECU. Doing this will put the fuel mapping into "Open Loop" mode, i.e. it will get no feedback and generally speaking will tend to run rich.

I will not offer an opinion or advice further than that, just saying  :038:

I removed the O2 sensors on both my Pans which smoothed out the  throttle response significantly. Dont feel the need on the Trophy. I didnt know emissions were checked on a bike, I dont recall seeing them doing it when I have taken it for a test anyway.

They do now, depends on the age of the bike and the regulations in force at the time of build / registration (can't remember which). The rules for many things have changed over the years and often you don't hear about it until you have to do something that requires involvement of the DVSA / VOSA. I could spend days reading up and go full anorack on you quoting this and that but these days I just deal with it as it happens  :038:
