Fuel Mileage

I was surprised (and happy) to see just under 50 mpg on a tank that consisted of a mix of back country roads and almost half a tank of trail riding in mostly 1st gear with a little 2nd gear. The knobs really kill highway mileage since 55 - 60 mph, 30 #, straight line riding nets < 55 mpg.

i have only done rough calculations but i think i am getting about ~50-55 ish. last time my fuel light came on at 81. i run premium 93 octane fuel in it but am rather disappointed with the mileage because it is nothing like the 71 advertised... i ride pavement mostly for now and push it hard from corner to corner on the twisties however so that may kill some of it it is all completely stock.

65-70 MPG on the highway, depending on how fast I go.

70-75 on the street.

55-65 if I'm having fun.

You folks realize that 70 mpg is not going to be possible for everyone........we all weigh differently

Hi ibismojo:

I can guarantee you the weight of the rider has a far less impact on FE than the weight of his or her right hand as the latter makes all the difference...

Good Luck

That's not a guarantee as a person weighing 400 lbs on a 300 lb bike will most definitely have a severe impact on FE vs the riding habits (good or bad) of someone who weighed 150.

Hi ibismojo:

I can see Jager rolling his eyes about now

As stated above, FE has a lot more to do with the weight of your right hand than it has to do with weight of the machine... Would I like to see the WR250R/X weigh in at 250 pounds vs. 300? You bet but in terms of FE, I am losing about 2 mpg with the additional gear weight yet still holding what I consider decent enough FE numbers while heading into the prevailing headwinds of an East to West, Northern Continent crossing.


2010 Yamaha WR250X Adventure Touring Project Bike - X-Country at 100 + MPG

Total Miles = (2227.52 miles)/Total Gallons = (21.511 gallons) = 103.553 mpg so far...

Weight hurts FE; your right hand hurts FE a heck of a lot more...

Another that has everything to do with our right foot vs. our right hand…


The 11 Super Duty w/ the Power Stroke's aFCD is ~ 1 mpg over actual from the FE calcs during the Phoenix to Chicago drive to place the 11 Super Duty in the Chicago Press Fleet.

Good Luck

Yes, I agree with how you ride has a lot to do with the MPG you'll get, unfortunately, one cannot change how much they weigh on the fly. That's fixed amount no matter how your ride. All things considered equal, the heavier rider will be less likely to hit the advertised fuel economy rating. That was my apparently-not-so-obvious point.

Greetings,
My first post here after reading some good threads. I was hoping the experienced members could give some advice:

I am considering buying a WR250X purely for it's mpg potential. Toward that end, should I / could I...

replace the 13 countershaft sprocket with a 15?
In addition to the above would reducing the rear from 42 to a 40 or 38 be a good idea as well.
Please bear in mind that performance is almost irrelevant to me.

Would removing the AIS and/or flapper and/or EXUP would actually hurt mpg?

My goal is to achieve 90mpg at a steady 65 mph,

Any advice is deeply appreciated. Thank you.

Dave

Personally, I'd just leave everything stock if you only want the bike for fuel range out of a gallon of gas.
It already comes overgeared, and basically putters along at a low enough RPM at 65mph, low enough that you're really not into the meat of the powerband while cruising at that speed.

Just wondering what kind of mileage you are getting off road ? I was out this afternoon rippin up the fire lanes and 68 mi later the fuel light is on I was thinking more like 85 or so. I am running 13 48 fmf power core opened up airbox and yes I probably ride it a little harder than I should

The first tank-to-tank fillup netted me 68 MPG. This was at almost 0 miles on the odometer. I never calculated it after that but the low-fuel light usually comes on just at just under 100 miles. This is almost up in scooter territory! Note that this is pure street riding. By contrast, my Triumph Thunderbird street bike nets about 47 MPG on a good day, about 38 MPG on a bad day. My four cylinder AWD car gets about 26 MPG tank-to-tank. I include my WR250R in my "green" credentials.

i just filled up and i did 230km's from 8ltrs 3.4l/100km as we use here.

I'm getting 60-70miles before my low fuel light comes on.

Got quite a few chuckles out of this thread.  Dont mean to  but I couldn't resist.  

I picked up a brand spanking new 2013 WRR last week and I'm beginning to think that either the fueling map has changed or you guys that get 70 to 80 mpg are running on magic fuel.  

Bone stock bike, unloaded, and I weigh about 190.  If I use the throttle for a bit of fun, I get around 50 mpg.  I did that for a few tanks and was a bit surprised by it since my KTM 990 gets about 43 with spirited riding, and its a 1 liter fuel eating machine.  

So for the next few tanks on the WRR, I really babied it, slow acceleration, short shifing, keeping the revs low riding mainly 55-60 mph (speedo indicated) flat roads, very little wind, sea level, temps in the 60's.  The absolute best I have seen is 61 mpg.  No way in hell this bike is fueled lean IMO.

So given that I will be seeing 50 or less more often than 60, does anyone know if they coming out with 7 gallon tank anytime soon?   

Fuel mileage aside, I really like the bike, very nice machine.

Since they put ethanol in pump gas everything gets a few less mpgs, 60-70 mpg might be possible on good ehtanol free gas if you can find it.

I ride mostly offroad and to have fun not save gas so my mpg are pretty low.

I took a guy for a kinda easy offroad ride a couple of weeks ago, he was on a stock wrr, I took my klr650 (I thaught other klrs were coming), we burnt about the same amount of gas lol. He did make it 157 kms without running out of gas tho, I thaught he was going to run out and I'd have to drain some out of the supertanker klr lol, the trip was longer than expected.

I've found most four stroke dirt bikes reguardless of motor size get about 50 mpg while riding on the road or easy open offroading, my klr does, my wrr does, friends 450s do, its more about pushing a non areo dynamic tall bike down the road than what motors in it.

60+ is easily possible if you stay under 60mph. Even with my commute being mostly 65mph I still get 58-61mpg... but one trip across town on the loop at 70-75mph and I'm into the mid 50s. Best mileage I ever got on it was before I knew about the speedometer error lol. Hence I was driving about 8mph slower than I am now at all times and the fuel mileage was consistent mid to high 60s.

Yeah.....um....... no.     

Did 200 miles total hwy (65mph) and another 200 miles off-road (ave 45mph) in 2 days. Mostly flat elevations.  Spent 60mpg.  13-46 gearing, Kenda270s, PCV + Autotune, Muffler redone by Ramz, carrying about 195 lbs (rider and gear).
 
Best .... Raymond

Just did 140 miles the other day doing a loop near Glacier National Park, some slab but mostly national forest/parks gravel roads.  Took 2.05 gallons to fill 'er up... you do the math.  The guy on the 500cc KTM got even better fuel economy, which I commented on elsewhere.  My bike is carrying about 225 once I have me and all my stuff aboard.

This kind of riding does not involve twisting the throttle for fun, lofting the front end, etc.  And the tires are at their full pressure as I don't need to air down.  Riding styles, tires and pressures, etc have a lot to do with how many miles you get out of a tank - but I assume we all already know this.  If you have fun riding whatever way you do, don't worry about it.

Well, then something is not right with the fueling on my bike or something has changed with the fueling map.   2013 R, bone stock right from the floor, slab, 55-60 mph (speedo indicated), flat, little wind, short shifting, 200 lbs max with gear, tires 28/34, I have not been able to get better than 60-61. Just tried it again today, 88 miles to the light, around 59 mpg.

You get better mpg's than I do.

I never get over 55 mpg and am usually much closer to 50 mpg.


But I get it with a smile on my face

If hes doing national forests, I dunno about up there but down here the speed limit is 25mph on park roads. The slower she goes the better her mileage since aerodynamics is her main hurdle. At a displayed 55-60, 60mpg isn't far off. My bike would be in that range depending on wind, hills, and gas. Winter blend gas has about 1.7% less energy, 10% ethanol knocks off another 3.3%. Winter gas with ethanol will knock a chunk off your mileage!.

Thanks for the replies folks.  Well see what happens when I load it up, air it down, bumping off the rev limiter on the trails.  

My guess is upper 40's, lower 50's.  Range is pretty important where I ride this bike, dirt or pavement, doesn't matter.  So I'm trying to get a feel for what I can expect under different riding conditions.  

Where I ride, a 200+ mile range is almost essential to do any serious exploring.  I reckon with 4 gallons I'll probably be in the 190-240 range dependent upon conditions.  That will work.  I tried out a bike with the 4.7 IMS.  Too wide for my tastes.  Makes it difficult for me to get my crotch over the gas tank to make the front wheel stick.

I'm going to try out the 3 gal IMS and carry a 1 gal or 1.75 gal rotopax and see how that works out.

Commuting to work and back roughly 12km one way I get 3.85L/100km (61mpg for you imperialists  )

my first gal used I went 70 miles and used 1.026, that was 68 mpg

My first tank, back and forth to work this week. 85 miles low fuel light came on and rode to 114 miles and filed with 1.808 gal. 63MPG
