Do Motorbikes (two And Four Stroke) Have Catalytic Converters?

Motorcycles, for the most part, do NOT and have never had catalytic converters. The standard for emissions did not change between 1980 and 2008. Advancing technologies allowed most motorcycles to meet the standard without converters. A few models have had them. The catalytic converter is one more thing to break down on a motorcycle, just as with any additional system. So if you can buy a compliant motorcycle without a converter you are much better off.

Catalytic converters cannot, in most cases, be added to any kind of vehicle for one reason. The fuel system must be designed to deliver a specific level of unburned fuel to the converter for it to be long lived. Too much unburned fuel hitting the converter significantly reduced it's life and performance. Additionally, modern catalytic and fuel control systems use one or more O2 sensors to make sure the mixture going to the "cat" is correct.

Motorbikes built since the 1990's more often have catalytic converters than those prior to this time. In countries throughout the world, there have been studies regarding the impact of 2-stroke and 4-stroke motorbike exhaust contaminants into the air. The conclusion has pretty much been a change in policy requiring the inclusion of catalytic converters be an added feature on these motorbikes.

From all I read, it appears most manufacturers have included catalytic converters on 2-stroke and 4 stroked motorbikes, for quite sometime. The majority of these motorbikes sold today, will have a catalytic converter. In the event you find one without a converter, if would probably not be a good idea to purchase it.

An older 2-stroke or 4-stroke motorbike, probably could have a catalytic converter added, although it might be expensive to do this.

Yes, the newer bikes do, there are 2004 and updated 2007 emission
compliance on all bikes, soon all bikes will have cats with a closed
loop, EFI system with O2 sensors, even HD.

Most bikes are getting away without cats now cause they leaned the EFI
and it passes the emissions without installing cats, but with that lean
adjusted EFI many bikes suffer from dead spots in certain RPM's, Yamaha,
Triumph, KTM is having that trouble.

Hello everyone, if it’s possible for you, just like me, to ride a motorcycle with a dead battery, and I will answer you with this article that it depends on the motorcycle, since they actually made several types of motorcycles. Many of them can be launched by clicking on it. With a dead battery, you can damage the motorcycle's charging system.

It is best to charge the battery. You can do this in several ways. Charger, charging from another car, installing a charged battery, etc.
