I own a ZZ1400 and I want to know if it is illegal to remove the catalytic converter? I see loads of people on various forums who have done a ‘de-cat’ and they reckon it makes the bike quicker.
However, just because loads of people do it doesn’t make it legal. I don’t want to go to the time and cost of taking off the exhaust pipes and taking out the cat only to find I have to but a new exhaust system later.
Firstly, good choice of bike (I too have a ZZR1400!) I have been asked this question a lot lately and you are absolutely correct. Just because someone on a forum has done it does not make it legal. In recent years, there has been a real push to make cars and motorbikes alike cleaner for the environment and to be fair none of us want to be breathing in smog.
The law has evolved over the years and long story short, it states it is an offence to use on the a road a vehicle which has been modified in such a way that it no longer complies with the air pollutant emissions standards it was designed to meet (if you are ever struggling to sleep I recommended reading the Road Vehicles (Construction and Use) Regulations and the Road Traffic Act 1988. It is WAY more effective than counting sheep).
If you get caught doing this i.e. ‘de-catting’ a motorbike that should have a catalytic converter etc. you could be looking at a hefty fine. Bizarrely though, as matters currently stand, motorbikes do not have their emissions tested as part of the MOT and there are load of companies out there ‘de-catting’ bikes.
