I would love to use a higher capacity bike such as a 600 like you say, but the MPG would need to be above 60-70 before I would give it much consideration. Ive heard good things about the new 650GS but budget will not stretch to that unfortunately

Consider any bike that has fuel injection and I don't see the Honda Varadero 125cc mentioned in the HUBB but it is a tall 125 bike that looks good for travelling.

BTW, yes, the F650GS single returns 70-75 MPG running on tarmac (personal experience) and the new G650GS has the same twin spark FI engine. That engine is in the F650 from about 2003/4, such as the Dakar model.

I hear that the parallel twin cyl F650GS which is a 800cc engine returns similar fuel economy.

I'd be thinking total lifetime cost. First rule IMHO, don't buy new, the hit you'll take by riding out of the showroom buys a lot of petrol. You can insure a 2007 650cc BMW or similar for less than some new 125's and filters/brake pads/ bits bought on e-bay are cheaper than the dealer. It gets even more worth thinking carefully about when your Chinese or Korean 125 manufacturer goes bust and no one can tell you which model year Honda they'd been copying.

Greetings thrifty DaveK,

I have been thinking along the same lines as you for a while now. I made the switch from big BMW for touring down to Honda and Kawasaki 250 dual sport bikes and haven't looked back. In my case, I have limited funds for travel and would rather go out longer on an inexpensive fuel efficient bike. My Kawasaki 250 super sherpa has a top comfortable cruising speed of 65 mph and the XR250 with high gearing about the same.

I was racing a high school kid in the mountains of Mexico last year. He was on a Honda Cargo 125 and had a top speed of 60 mph so I could catch up to him in the straights, although he was pulling away from me in the corners leaning that thing over like he was in a motoGP race . So these small bikes aren't really capable of high speed cruising like your stated goal of 70-75 mph, but riding a slow bike fast is an awful lot of fun. And the small bikes are perfectly acceptable for travel on third world back roads and byways.

I intend to tour South America on a 125 Honda. Have read of others doing the same. You can buy the small 125 Honda in Chile for 800 UK pounds brand new off the showroom floor. These bikes are quite common throughout the third world and finding parts and tires is much easier than for big dual sports. Most people in the US where I live think that a 650 is a small bike, so it involves a different mindset to go small. If you are coming from a large dual sport, it feels like you are riding a fast flickable motorized mountain bike. I pack light and only take the essentials which keeps less weight on the bike. If you can make these compromises then you can save a lot. Everything is less expensive on a small bike, less for fuel, bike parts, initial purchase cost . It all adds up.

With that said, I have traveled with folks on BMW fuel injected f650 and they get excellent fuel economy. The gal I was riding with was getting 60 mpg or better (non-imperial wimpy US gallons) regularly. Not as fuel efficient as a 125 Honda but still quite good.

Honda also is coming out with a 125 fuel injected motor that promises even better fuel economy.
Others may have better ideas.

Cheers,
John Downs

Im a bit of a fuel economy obsessive and i got my first DS bike with that in mind, i figured the more economical my bike the further i can afford to go touring.

On my Suzuki DR350 I get 64 mpg (US) on motorways at around 70mph (any more is a bit windy for me but she will go to 80+mph) and nearly 70mpg on country roads plodding along at 50 odd mph. If you are happy to go slower i think something like a DR250 or a Yamaha Serow (225 cc i think) will doubtless give better economy but still hit reasonable speeds.

I should point out that it is possible to get my mpg way down, when i ride in the city and race cars off the lights etc. but i guess thats true of all bikes.

I used to do a 100 mile partially motorway commute on a 125 bike (suzuki GN125) and i found it to give back far less than its stated mpg just because i was reving the hell out of it to keep myself at speed (and out of the wheels of the lorries).

I havent tested the new DL650 2012-model long enough to know the exact figures... but I just read, that a Finnish magazine got 4.1 liters per 100kms average consumption (and in the same article it says some German mag had got 3.8 per 100kms). I do wonder, if those could really be AVERAGE consumptions, as bikes usually do get a hammering by the journos! But anyway it teems that there´s an improvement over the old model, which in turn wasn´t thirsty at all.

The new one´s got a 20 L tank, whereas the old one has 22 L. But if those figures are right, then their range could in fact be roughly the same (almost 500 kms without refilling - which is nice for a non-aftermarket tank!) And regards consumption, it would also put the new V-Strom just about on par with the small GS, but with the bigger tank, the DL650 would have a longer range.
