How much milage on the road can I expect with a full tank on a 2009 250s?

 

I hit reserve at 100 miles and can get about 30 more miles till dry.

On my 07, which has a 1.9 gallon fuel tank ( I think 09's and 10's have 2.0 gallon tanks ), I hit reserve consistently at 85-88 miles.

although in a few days mine will have a 2.7 gallon clarke tank.

 

120km or about 80 miles to reserve on my 09 with Q4 and jetting on the road.
if you do a search theres lot of treads on the same subject

 

07 250, 1.9 Gal tank, TM36 carb. I hit the reserve at 80 - 85 miles on the trip odo.

Pretty crappy mpg isn't it? That's less than 50 mpg. Those big bmw adventure bikes get 50mpg. Heck, there are cars that get 50 mpg. Our little quarter liter engines should be able to do better. Oh well, lots of smiles per mile.

 

On my D-Tracker, I get 66-68 mpg in town. Best I got once was 71 mpg. I´ve been riding around 110-115 miles before I have to make a gas stop and still have some left.
I´ve been logging it since I got the bike from the dealer last February. It´s a quick and easy way to know if there´s something wrong going on.

 

Think you got your mileage math a little mixed up. I get 88 miles per tank when I hit reserve.

On a 1.9 gallon tank, reserve is set at 1.4 gallons. Meaning there is 0.5 left for reserve.

So 88 miles on 1.4 gallons comes out to 62 mpg.

When completely stock, I was hitting 70 mpg.

 

I read 80 miles to reserve and then 30 more until dry, worse case from above. So 110/2 is 55.

Remember that our odos are 10% off too. = 49.5

Why not 100 mpg? Even a solid 60 is **** poor. Just the way it is I guess, I get 15 in my pickup.

The KLR650 guys claim to be well into the 50s as well.

 

I think it comes down to physics and technology. Yeah it is a small engine with a small carb, but it still has to work really hard to please us. With a strong headwind we still try to do 60 mph with the engine straining. I think its amazing that this little 15 cubic inch engine can do so much. If we limited the KLX to 40 mph and power wasn't important and tuned accordingly, we could probably avg 80 mpg. The bigger bikes are close in mileage because they don't have to work as hard to produce the same results. So this is the physics side of things.

In terms of technology, our bikes are still stuck in 1981. They have crude inefficient carbs on very basic engines. If our bikes had computer controlled fuel injection, variable valve and cam timing, computer controlled engine diagnostics, etc. We could probably get a lot more mileage out of them, but our bikes would cost $12,000.
