Last week on the YPK blogspot, we informed you that all three of YPK Motorsports' brands: Yamaha, Polaris, and Kawasaki had all delivered their new 2011 vehicles to the store. This is always an exciting time of year for us....kind of like Christmas in July, if you will. We love seeing the new specs, improvements, and colors that all the brands bring!
We discussed the crazy list of new improvements for the 2011 Polaris RZR in our last blog. This week we will be discussing the specs and improvements for the 2011 Kawasaki KX250F motorcycle. Now, it used to be said that the factory guys get all the good stuff. Their bikes are faster, lighter and just plain more tricked out than the bikes you can get off the showroom floor. There may be some truth there, but that’s changing....Fast! The gap between production and factory-prepped motocrossers has never been narrower. And with the introduction of Kawasaki’s massively reworked 2011 KX™ 250F, that gap just shrank a little more.
For 2011, there are nearly 30 upgrades to the Kawasaki KX250F !! These many upgrades reflect the rigorous testing and development happening at Kawasaki. Their engineers started with what’s become the gold standard in 250 class racing, the 2010 KX250F, (winner of the 2010 AMA East and West Supercross Lites titles), and improved this great bike....even more!
Loads of engine modifications have made the latest KX250F an absolute corner-to-corner screamer. Refinements to the 249cc single include higher compression, a modified top on the exclusive Bridged-Box Bottom piston, higher valve lift, longer spark plug design, and a new coil that offers a hotter and longer-lasting spark. And, the addition of Digital Fuel Injection (DFI®) produces stunning – and more useable – power. The system automatically adjusts to suit track and climate conditions, even when the going gets rough.
An optional ECU Setting Tool allows racers to select from several different ECU data maps or fine tune a custom map. The tool can also record up to six hours of data, including engine rpm, degree of throttle opening, coolant and air temperatures, ignition timing, fuel adjustments, gear position and system voltage.
Headlining the chassis changes on the KX250F is Kawasaki’s new Separate Function Fork. Instead of a conventional fork design, the SFF separates spring and damping duties (one in each leg) for improved performance, less friction, lower weight and easier adjustability. The right leg has the spring, with a larger main spring/rod assembly than traditional forks; the left leg handles damping, with rebound and compression damping adjustable on the fork tube.
As for ergonomics, the KX250F’s bodywork offers riders a slim interface and a natural positioning that make going fast a simple affair. The upgraded seat provides excellent seated grip and rider mobility, and features firm urethane foam to hold its shape longer.
With all of the changes for 2011, there is no limit to the fun you can have on this bike! Whether it is riding the trails or racing at the track...you will get there in record time. Come by YPK Motorsports today and check one of these bikes out!!
