I would have to say one of the biggest changes for the 2011 CRF250 would be the 94db Exhaust system. It may not sound like much (pun intended!), but Honda isn't one for just bolting on a muffler, so this change resulted in a lot of other changes. First off, to make up for the quieter muffler, the CRF250R received different mapping and also changed the rear sprocket from a 48 tooth to a 49. This resulted in better throttle response and a much improved bottom to mid range power. How does this help us? Well, the 2011 CRF is a lot snappier than the 2010, and it's now able to pull higher gears at a lower RPM. This makes for a great bite in the lower gears, or if you want that smooth delivery, than shift up a gear for controlled roll-on power. We were all surprised with the roll-on torque of this machine because it is not common on 250Fs, especially for the larger riders. Honda has definitely figured this one out. So the little Red engine improved over 2010 with better response, better torque and a much more expressive motor, all while dropping the sound down to 94db. The funny thing about the 94db muffler is that it doesn't sound a lot quieter, but it gave the bike even more of a deep throaty growl compared to last year's model - Not bad at all in my book. And to show Hondas attention to detail, the subframe, side panels and rear fender were also changed to accept the new muffler. Well, maybe not only to accept the new muffler, because now, most of the CRF250 parts are compatible with the CRF450. That makes the subframe, all the plastics, gas tank, and of course most of the already matching hardware interchangeable.As for the handling, well the CRF250 has always worked amazing. It's light, nimble, easy to throw around, while still being very controlled and stable. It doesn't take much time for the majority of riders to feel right at home on this machine. So for 2011, Honda decided to give us even more of that feeling. They started off with a larger piston in their Honda Progressive Steering Damper - Going from 20mm to 24mm on the damper piston givving the new CRF improved tracking traits over last year. We didn't have any complaints, so she must be doing her job.
