why klx250 has limited low end torque?
 

I mean if this is designed as off-road bike shouldn't low end torque be obvious to have? I read somewhere that even crf250l has more torque and low revs.
Is that somehow adjustable at all?
thanks

Hey, you may get a better response posting in the klx 250 sub forum
KLX 250S - Kawasaki Forums

"Each scoot makes 20 peak horsepower coming on in the low- to mid-8000-rpm range. Only half a foot-pound separates peak torque, with the Honda registering 14.0 ft-lbs and the Kawi 13.5 ft-lbs. However, the Honda scores a bonus point here since it churns out its best twisting force earlier in its rev range (5800 rpm), whereas the Kawasaki doesn’t peak until 7100 rpm." - Motorcycle.com

"The Kawasaki’s power delivery is generally linear, but engine response at small throttle openings during on/off throttle transitions seem ever so slightly delayed, again likely due to lean jetting to meet modern emissions standards. If we owned a KLX, we’d definitely look into fitting it with a jet kit. But when the Honda starts instantly, and without thought on the rider’s part, well, why not have EFI…?"

I can give them one good reason. If the Honda performs close to equal with the KLX and the Honda has EFI keeping at peak performance, just think about what happens when the Kaw is jetted proper and then do the Marcelino mod to pump up the performance. Now you have hotter engine with stronger mid-range after the cam mod for sure. So with under $100 worth of jetting and some well documented cam timing play you now have a hotter performing bike than the Honda. Based on my personal experience the jetting and cam timing makes the KLX start extremely easily and warms up within seconds.

Remember, all those tests are stock bikes. A bit of tweaking of the KLX picks up as much as 5 hp and makes starting a non-issue. Perfect for a rider willing to do a bit of work. I did it with mine and it does the job. Unfortunately motorcycle media don't do any work anymore. If that was a 1970s DirtBike! test and they knew about fixes they'd have done them and reported the results. Listing them as "off road only" modifications of course.

well since in Europe we have klx250 fuel injected I was comparing both EFI models.

Then simply refer to the Marcelino cam modification that boosts both horsepower and torque over the stock bike. He used the EFI bike, living in Spain. So really, the same is still true.

I'm sorry I omitted the fact that he increased power by doing a simple retiming of the cams to a relatively common known level. For whatever reason Kawasaki had the timing set up significantly excessive advance on the exhaust and significantly insufficient advance on the intake per his comments. By modifying the setting it can be remedied. The beauty of it is that it can be done for nothing more than the labor to do so.

I guess we now have Europe covered too. Of course had you done a bit of a profile simply listing your being in Europe I'd have known it was EFI.
