I am not so sure about that.  Bikes are more fuel efficient, but their emissions/mile are typically much higher than a car. 

Here is a comparison I posted up in this thread

Hydrocarbon Emissions (grams per mile)
2002 Ford Expedition 4WD : 0.15

2002 YZF R6 :**4.19**
2002 BMW R1200C : 0.97
2002 Honda VTX1800C : 0.48

I stand corrected. You wouldn't happen to have those numbers for a bike with a cat would you?

This is the study I pulled those from:


It is kinda dated, but there may have been a bike with a cat in 2002-2003.

That study was eye opener for me too, I had no idea until I started comparing numbers.  I still think two wheels > four wheels, but if we want to promote them as a green option, there will be a sacrifice in performance.

Maybe not so much a sacrifice in performance so much as we leave them stock or start the dreaded emissions testing.  If bikes had the same emissions standards as cars do then they would pollute much much less.  Don't flame me on that one, neither of my cages have any emissions stuff and my bike has stage 2 jetting.

monsters had cats back in 2002

Which one?  I've worked on a few and the DSS sure didn't and the SSS bikes didn't show up for a couple years on

My 2003 620 has cats in the pipes and the pipes are the same back to 2001

Interesting... they changed up stuff.  620 do have then in the headers.. though they moved them to the silencers for the 695 - or maybe added...

Well... color me corrected

I'm just curious as to the HC count of a new unmodified bike. The R6 numbers can't be that bad in stock form.

I shouldn't have said pipe, they are not in the header

They are in the slip-on

If you are talking about hydrocarbons, carbon monoxide and oxides of nitrogen you are correct, but the story changes when you talk about carbon dioxide and fuel consumption (carbon footprint), which, right or wrong, is where the pressure is on.

Also note that these bikes are pre Euro 3 emissions and only the BMW has a catalytic converter.

I don't think so.

Give people incentives to ride their bikes to work. That will cut down on pollution, congestion, and wear on the roadways. let's say a tax break for someone who rides 8,000 miles a year. Everything is in place to monitor mileage already, such as state inspections or yearly registrations.

The only incentive I would accept is a personal valet waiting to hand me my suit after I have a shower upon arriving at the office.  It was 96 deg the other day and I have a 25 minute drive (by car) to the office.  And I have to wear a suit.

I know there are plenty of people who don't wear suits to work, but when you are talking about the bulk of people in many cities -- you are talking about suits and ties (and blouses and skirts etc)

Bikes don't cut it.  I have a hard time even on the Monster.  Just doesn't work.

Nope.  Incorrect.  Motorcycles did not require catalysts until 2006 MY. 

My 2005 S2R udder weighs half what a 2006 S2R udder weighs.  The MY2005 models had no catalyst.

Tesla did well.  Now Honda.. wow they just cloned the prius with their new hybrid

Except for the whole Hydrogen Fuel cell thingy
