Well, it does not explicitly say that they are rigging the bike to pass the test.
It just says that for £50, they can tune the bike to pass.
And in some instances, it costs £100 to £150.I imagine that they'll pop a new air filter, install some kind of bolt on catalytic dB killer, then tweak the carbs to make the old bike run lean then run the test.

Maybe I was being a bit oversensitive, due to lack of sleep. On first read I just thought the copy could have been written in a more generalised way - "many older bikes can actually be tuned and serviced to reduce their NOx, meaning they meet the ULEZ".
And to be clear, I don't see anything wrong with tuning a vehicle to meet emissions regs - it's basically what 99% of new cars nowadays do, to meet the specific regs of each region.
Also it means my faraway dream of a Suzuki Savage/L650/Boulevard bobber thumper is back on the table... albeit a long way off.

Getting the bike to run properly.
2 strokes pass the NOx test easily as a major factor NOx creation in combustion is combustion temperature, the higher the combustion temperature more NOx hence diesels have the issue more than petrol fuel vehicles.

That's good to hear. But if I were Riverbank I wouldn't be overly happy with an article which reads like for £50 they can rig the bike to pass the test.
