Miles per Gallon: would that be US or Imperial (UK) Galloons?
Or Liters per 100 Kilometers? Or km/L? |
I have a 2009 KLX250S with 22,000 miles on it. I've owned it since new and have made no modifications to it. The speedo is off by about 10%, when compared to a GPS. I believe my ODO is also off by 10%. I regularly can ride about 100-110 miles before having to switch to reserve, and then I can go another 35 miles before I start getting nervous. The fill-up will generally be about 1.8 gallons (tank is 2.0 gallons, including 0.5 gallon reserve). The last few fill-ups I averaged right about 75 mpg, but that is with the bike's trip ODO reading. I use my bike to commute to work, mainly on 45 mph city roads with about 2 miles on the expressway.

I get about 55mpg, mix of city, 60mph highway and trail... I'm not gentle on the throttle...

I gotta ask...was that mileage corrected or at least verified with a GPS or something? I don't doubt it, I'm just curious. I'm sure shifting at 4.5 helps a lot.

No, but I didn't go above 45 mph either. However getting on it, or riding like I stole it I usually stuck around 58-60. My 250 never got better than 53, and when I did my 351 I never got better than 55. The big change was going from the cv carb to a properly tuned pumper tm36-68. Hell even Bill Blue was getting 70 I think from his tm34 pumper. Most low mpg comes from the CV carb imo
I ask because I just got back from riding back roads. Some were well paved and we were cranking it, others were rough pavement/gravel/dirt. I was on my KLX650 running it a lot harder than normal, running 4500-5500 against a 7000 rpm power peak, yet I still saw over 60 mpg every tank. Stock gearing, full truly race exhaust sold by BajaDesigns in 94-95 or so, big bore 678cc, Dial-A-Jet on the carb for fueling properly, cut up air box lid, yet it still does around 60 mpg no matter how it is ridden. That is why it seems so wrong even a big bore should do so lousy. I'm going to check mine while commuting to school starting in the next week or so. |

Pretty pathetic. I wonder why. What sprocket?

My vstrom gets 65mpg and it's a whole hell of a lot faster haha |
