2011 Suzuki RM-Z250

0

For 2011 Suzuki has taken its potent RM-Z250, and have fine-tuned it into an even more capable machine. The 2011 RM-Z has seen numerous updates: it now meets a stricter AMA noise limit (94db) while maintaining smooth engine output; the intake and exhaust timing has been changed for better engine feeling with lower noise output; the exhaust pipe length has been changed for better engine feeling with lower noise; ECU settings have been updated for more linear acceleration and improved over-rev; and the radiator hose routing has been changed for more efficient cooling.

In addition, Suzuki has focused on improving operation and overall feeling (primarily in shifting and starting). The 2011 RM-Z250 features improved lubrication on the center of the clutch and counter shaft for better durability and improved clutch feel; an updated transmission (focusing on 3rd and 4th gear) provides improved durability; and the kick starting arm has been redesigned for improved starting.

2010 Yamaha YZ250F

 Key Features:
     
  • The all-new, Bilateral Beam frame is specific to the 250 and is more compact than the previous generation chassis. This places the rider closer to the front wheel, which delivers superb rigidity balance for unmatched lightweight handling and cornering. This nimbleness lets the rider get on the gas sooner out of corners and cross the finish line with less fatigue – even on long motos.
  • The optimized engine delivers a new level of power in low-to-midrange, with a great torquey feel, exactly where riders want it. That is due to the new straight intake boot that enhances breathing, new carburetor that provides excellent throttle response and fuel atomization, and redesigned valve train components that reduce inertial mass and boost low end torque. Exhaust is also enhanced with a new D-shaped exhaust port and newly designed exhaust system. Ongoing refinement to the suspension and engine produces an amazingly balanced, light-handling machine with performance that’s accessible to all levels of riders.
  • All new styling emphasizes the bike’s light weight and nimble handling character. The sharp, horizontal lines set the bike apart, with a clean, aggressive look.
  • KYB® suspension has been recalibrated front and rear and is tuned to work with the new Bilateral Beam frame for unmatched handling. The clutch lever has a lighter pull feel even though the clutch has stronger engagement. The new clutch also has a wider engagement range that will give riders an advantage off the line. . . shift after shift, moto after moto.
  • There’s no disputing the YZ250F’s unmatched four-stroke prowess – it was the 1st four-stroke 250 motocross bike on the market, the 1st to win an international race, the 1st to win an AMA® Supercross ® and the 1st to take an AMA® U.S. Supercross Championship® title, as well as the first to win an AMA® National race.

2010 Honda CRF250R

0

The CRF250R likes to win. Plain and simple. In fact, this machine has grown so used to taking checkered flags that it considers the top of the podium home. It’s not easy, though, because when you’re this good, everyone else is always gunning for you. And that means you always have to stay that much better, which is exactly what this year’s all-new-from-the-dirt-up Honda CRF250R has done.

And we didn’t have to look far for inspiration, adapting many of the same cutting-edge features found on the open-class-leading and championship-winning CRF450R. Like Honda’s revolutionary batteryless fuel-injection system. A lightweight, more potent Unicam engine. An innovative new single exhaust setup. An all-new twin-spar aluminum frame. And our exclusive Honda Progressive Steering Damper (HPSD). It even takes some serious new styling cues from its big brother.

2011 Kawasaki KX 250F

Introduction
 
It’s an old refrain: The factory guys get all the good stuff. Their bikes are faster, lighter and just plain tricker than the motocrossers you can buy off the showroom floor. There’s some truth there. But that’s changing. 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.

2011 KTM 250 SX-F

When you have a bike in your range like the 250 SX-F, which has been the dominant force in the World Championship MX2 class for years, then it would be very easy to just sit back and carry on as before. Luckily, however, that’s not how things work in racing, or at KTM for that matter. That’s why the new 2011 generation is being launched with a completely reworked chassis, new bodywork and the next stage in engine development with fuel injection.

– New chassis (PDS)
– New airbox
– Air flow optimized intake boot between filter and carburetor
