Ben: motorcycles tend to have alot more power per pound then cars, an exception of this is my cb125, with it's 12hp engine, of course it gets about 65-70mpg, but it's air drag that keeps it's top speed at 55-60mph, to reach that 60mph I have to duck down, and tuck my knees in, but alot of motorcycles have ungodly amounts of power for their size, and engines that rev to 10,000-15,000rpm, and even crotch rockets aren't very aerodynamic.

i wish the war would end so they would start building these for sale.

but when the war ends fuel is going to go down and then they might not build them.

Oh, two wheelers, how did I miss this thread!

I've got a couple of bikes:

2005 Suzuki DL650 V-strom: 55 MPG (never tried to hypermile, but we shall see this summer)

1987 Honda CN250 Helix: 72 MPG, but getting better with every ride. Soon to be sporting fuller tires and some aero bits. I just have to figure out a way to start it without having the read brake depressed; it has a CVT, so I figure I could do some EOC and get the FE way up!

I was anxious to get a feel where the bike is at on consumption, so I took a fillup at 100 miles. Very rough first indication is ~88MPG I'm in the hunt!!

I like Craig Vetter's webpages about the motorcycle mileage contests of some years ago:
http://www.craigvetter.com/pages/470...PG%20Main.html

Aerodynamics seem to be the biggest factor in motorcycle mileage.

Best I ever got on my RC-51 was 42 mph. My '68 airhead BMW R-60 gets about 45 mpg.

I have an old 1975 Kawasaki F7 175cc Enduro that I've used to commute with off and on for many years now. It is a 2-stroke rotary valve single, and it usually gets between 65 and 70 under normal conditions. Recently I began riding it on a 40-mile commute on secondary country roads at about 45 mph and got as high as 77.1 for a couple of tanks, when the wind was mostly at my back. It does not like to go much faster than that under any circumstances, and neither do I, when I'm riding it... Know what I mean?

Ecomodding techniques have driven the mileage on my V-strom to 60 MPG! Would never have guessed a 650 could get that high with so little effort.

I have been doing a little "pulse-and-gliding" on the electric cycle.

As long as I am not turning the throttle, the motor isn't using any power. It is suprising how far I can just coast.

I have noticed that it takes more juice now because of the 36V contactor. I think those things were never designed to be more efficient, because the forklifts had such huge battery packs. I might eventually want to swap out for a better contactor.

Also, I would like to convert to LED lighting, it's just time and money that prevents it. Plus, the cycle works just fine the way it is, and is fairly efficient, so I find it hard to justify the expense right now.

Cb250

My Honda Nighthawk CB250 has similar characteristics to Ryland's CB125 but with a top speed of 75 and a rock-bottom of 70 mpg. If dcb is really up for the challenge i'll run a tank clean (~230 miles) and see what happens...
