I had an R100RS that got about 50 on the highway, and an 1100cc Suzuki
a few years later that did substantially better even though rear tire
life was poor. I expect that newer stuff is at least a bit improved,
but whenever I hear the hogly stories I always figure it's an urban
legend designed to make wives more amenable to an insane purchase. :-)

My first bike, a 65 Suzuki 80 had a 1.5 gallon gas tank, top speed 55
mph, 62 downhill with a tail wind ;~).I filled it up once a week and
drove to school all week ( 28 mile round trip per day) by Friday night
I'd have to flip on the reserve. I'd have to drive it wide open to keep
up with traffic. My 1966 250 Ducati single, primitive carb and all
manages 68 mpg on the highway. Here's a link to high gas mileage bikes.

ICE Fuel efficiency can be maximized on highway. Recently,
I got 55 mpg on the highway using a 2006 Toyota Prius
(1200miles Ohio/Pennsylvania Turnpike, avg speed 55 mph) and
I got 32 mpg on the highway using a 1990 Honda Accord LX
(1200miles Ohio/Pennsylvania Turnpike, avg speed 50mph)
however in both cases I was driving in temperatures above
60 F. When the temperature drops below 40F and I'm driving
in city stop and go traffic - my fuel efficiency drops signficantly
( the 1990 Honda Accord drops from 32mpg to 20mpg).
The fuel efficiency of motorcycles and scooter  is going to
also depending on the driving conditions. Your reported
top FE experience for motorcycles is much better than
what I've heard in the washington DC metro area which
is 40-50 mpg range.  Maybe its the colder weather.
Alternative sources also suggests that 45 mpg is a more
realistic number for 1200cc Harleys.

1966-1997 Harley with 1200cc gets about 36 to 49 mpg
1998-2009 Harley with 1200cc gets about 38 to 50 mpg

While a scooter might get 55 mpg and it might be
able to achive speeds of upto 55 mph - it may not
accelerate, brake, or handle well enough
on the highway to safely do so.  As stated earlier,
safety is not entirely in the control of the bike's
operator so even with a more capable operator
- the risk are still higher for the bike's operator than
on a enclosed motor vehicle like a car or truck.
With the exceptions being three wheeled
vehicles which totally enclose and protect
the operator like the Aptera models (which
are only sold in California) .


True. However,
VW will be selling the Polo in the USA in 2011 and
Toyota is planning to sell a hybrid version of the Yaris in 2011
both should get up to 60 mpg if my preliminary
information is correct. However, in order to get 60mpg
both vehicles would have to operate under a kind
of computer controlled throttle economy/urban mode.
Both should also sell for less than 20,000 USD too.

Currently - the only way to 60mpg from any
ICE vehicle in the USA is via hypermiling techniques
- cars in the USA are just way too heavy

One of the reasons some Japanese and European
cars can achieve 50 to 60 mpg is because
they are much lighter in weight and can be
mated with a smaller more fuel efficient ICE.

In the UK, Axon Automotive has taken
this to the extreme and has built an extremely
light chassie for a 2 seater coupe that gets
100 mpg. See

With cars gas mileage is a matter of gearing, streamlining and how heavy
your foot is. During the summer I can coax 53 mpg out of my 99 saturn at
55mph drafting tractor trailers, which is the perfect speed for it's
gearing (1800 rpm @55mph). City driving is another matter no matter what
you drive, scooter or car, but a scooter is going to get much better
mileage than you claim on the highway  (30-35mpg).




Here's were I got my figures:
http://www.totalmotorcycle.com/MotorcycleFuelEconomyGuide/Harley-Davidson.htm





It's a matter of power to weight ratio, a 240lb scooter with
10 HP is 24 lb per horsepower, my Saturn weights 2400lbs and
has 100 HP, the same power to weight ratio. In town a scooter would have
no problem keeping up with traffic, few people are going to use one for
anything other than short trips anyway and off major highways.


As stated earlier,

Which at that weight is likely no safer than a scooter or motorcycle ;~)

So a fat guy has no gas economy on a scooter.
LOL
