2010 Kawasaki KLX250S


Posted on by 5

Dual purpose motorcycles have never been quite the same ever since the Kawasaki KLX250S was presented. They are now even better! Combining awesome engine performance with light enduro handling, the KLX250S is a never ending source of fun both on and off the asphalt and a very possible leader of the quarter-liter dual-sport class. Let’s just see how.

 

Introduction

The original Kawasaki KLX250S has made a name for itself thanks to the practicability and fun that characterized it. In order for a bike to be practical, it has to be street legal, but the thing with this KLX is that by taking a look at it, you frankly don’t know where to situate it best.

Kawasaki KLX250S

The 2010 bike features quite a few chassis refinements or better said changes. To begin with, the 43mm inverted cartridge fork now joins the steel frame at a rake angle of 26.5 degrees and a trail of 4.1 inches. Also, the 16-way compression and damping adjustable unit now offers 10.0 inches of travel instead of 10.2 on the 2009 model year. The bike’s overall length was reduced to 86.6 inches from 87.5 inches and, also, the bike is overall 0.2 inches wider (now 32.3 inches). Shortening length also meant reducing the wheelbase to 56.3 inches from 56.7 inches. The ground clearance has been increased from 11.0 inches to 11.2 inches, which also positions the seat slightly higher, at precisely 35.0 inches from the ground. The curb weight now equals 297.7 pounds, but at least the gas tank capacity is of 2.0 gallons.

Given the fact that the Kawasaki KLX250S was new in 2009, this model year comes to correct a very possible enthusiastic approach towards the given class and equal up the bike’s scales.

History

Riders seeking the perfect dual-sport motorcycle are not impressed by big displacements or dimensions. They simply crave for a lightweight bike with decent power which would have to be properly delivered. Oh…nice styling won’t heart anyone and the riding position must be dream-like. This is what Kawasaki engineers and designers concluded before taking their clean sheets of papers and designing the bike that would raise dual-sport standards and become a true riding companion for people all over the world.

This wonderful initiative was taken no more than five years ago (better late than never), and the bike first saw the motorcycle saloons and test drives as a 2006 model year.

The motorcycling public received this bike with great enthusiast as it proved capable of enduring harsh riding conditions with the help of its 250cc four-stroke, liquid-cooled, DOHC, four-valve single.

Proof of the fact that Kawasaki people were right when designing it, the KLX250S went way further than its target public and managed to be the right choice for the most advanced enduro and motocross riders.

For 2009, Kawasaki decided it was time to upgrade the bike’s main features and give it a nicer look. Ideas became facts and the bike featured an updated braking system, smoother engine, a more comfortable seat, and a new exterior design.

Competition

Suzuki DR200SE

Suzuki’s closest dual-sport motorcycle to the KLX250S is the DR200SE. Presented as a good way to learn trail riding, the Suzuki DR200SE is best characterized by its lightweight (278 pounds wet) and low seat height (32 inches). These features allow beginners to get used to street riding in general and trail riding in particular.

Suzuki’s 199cc, four-stroke, SOHC, single cylinder, Twin Dome Combustion Chamber (TDCC) engine is ready to power it up through the rough terrain and in collaboration with the suspension, brakes and tires, it is a true dual-purpose machine.

Yamaha XT250

Yamaha’s alternative to dual-purpose quarter-liter motorcycles is the XT250, which isn’t heavily refined but still a 2010 model year. No matter the conditions out there, this bike is ready to take the XT name even further with the help of its 249cc air-cooled, SOHC, 4-stroke single. Easily identifiable by its round headlight and distinctive white/black color, the Yamaha is not just another motorcycle on the trails, it’s the one sitting right next to the KLX250S.


Exterior

Kawasaki KLX250S

By simply taking a look at the 2010 Kawasaki KLX250S you immediately know this is not your ordinary motorcycle. Dual-sports are known for combining elements from off-road bikes with those of road bikes, but sometimes, just sometimes, manufacturers blow away any expectations and deliver an incredible looking motorcycle. In 2010, when it comes to dual sport bikes, the Kawasaki name will be on everybody’s lips.

The Kawasaki KLX250S features a high-mounted front fender, mudguards, a petal disc front brake and it seems ready to hit the trails. It actually is, but where you would expect to see a number plate, surprise: there’s a street fighter inspired headlight. Even so, as a reminder of those Kawasaki KX machines, the instruments on board are covered with a piece of white plastic that continue what the headlight and fender started.

Unable to take our eyes off of it, we continue admiring the side panels with the Kawasaki name on each side, complete with new decals. The seat is made out of urethane for a firmer feel, but what really stands out is the straighter handlebar profile.

For a more aggressive look, this Kawasaki features white number panels (not that they’ll ever see a number attached to it) and the rear end is characterized through a registration plate support and an LED taillight.

The wheels also look aggressive with the help of their 4mm thicker spokes, and the D-shape swingarm makes it look smoother and less of a jumper.

Color choices for the 2010 model are Lime Green and Ebony.

Press Reviews

Kawasaki KLX250S

"The KLR650’s little brother has quick throttle response and feather-light steering to help avoid obstacles in your path (helping to keep the desert tortoise population thriving). The whole package makes for a motorcycle capable of almost anything." – motorcycle

"Everything about the KLX250S is on the gentle side. The suspension is as soft as the mellow power delivery and the riding position is painless. On the trails the shock and fork absorb the rough stuff admirably so advanced riders will be able to easily push the KLX to its limit." – motorcycle-usa

"Displacing 249cc and with one 72mm piston moving through a 61.2mm bore, the KLX doesn’t so much accelerate but more gently gathers speed. On two-lane blacktop this takes a little reprogramming as you get up to road speed, but once there, the KLX will zip along at 65-75mph quite happily." – motorcycling. Speedtv

"This engine is perfect for a beginner straight from the factory, this is mainly because the E.P.A. has enforced restrictions that limit it’s potential. The good thing about the restrictions is the bike is pretty forgiving, also you will be able to get 70+ miles per gallon out of this little monster." – bestbeginnermotorcycles

"It’s not what you’d call comfortable for extended highway stints. And though nobody’s going touring on a 250cc single, the revamped chassis is quite stable at speed. It’s a perfectly agreeable way to reel in the paved sections of any dual-sport loop, or stand in for some fuel-swilling four-wheeler around town." – motorcyclistonline

Price

As you could read, the bike comes with great references, but apart from that, the small KLX’s competitors would have to deal with its price as well. A key factor for dual-purpose motorcycles, the MSRP has to be kept down in order to decisively win the battle and start writing heavy pages of history.

In this case we are talking about Kawasaki’s talent to offer so many positive features for the advantageous price of $5,299. Do I hear a good bang for the buck?

Conclusion

Kawasaki KLX250S

Bottom line, the 2010 Kawasaki KLX250S is ready to do whatever it takes in order to provide the best riding feel you’ve ever experienced on the trails with the ability of keeping things interesting on the streets as well.

By offering a well balanced motorcycle which looks good, traverses any kind of terrain in the weekend, and still manages to take you to and from work on Monday, Kawasaki proves it has the power to adapt motorcycles in any possible way.

i love kawasaki...i am 14 years old and i am wondering wat bike would be good for me... i am interested in going fast and a bit of motorcross.

Hey DaveW same cold problem here,Bike is firing, and compression is good??dealer & techs from Kawasaki Canada tried everything with no luck approx 20 hours into bike? last resort is new Carb. now on order..?? my fingers are crossed.

The bling doesn’t stop there, either, as there’s a set of 43mm inverted cartridge forks, which offer excellent rigidity and consistent damping performance; plus 25 centimeter travel contribute to the straight-line stability, and perfect handling.

I recently purchased an 09 KLX 250. The jury is still out. My biggest complaint so far is that if the temp drops below 50 degrees it flat won’t start. Won’t even fire. It’s been in the shop now for the past week because the pilot jet is plugged. My dealer tells me this is pretty common. They leave the factory set extremely lean and the jets plug easily. Larger jets will hopefully fix this and maybe improve the performance. I know it’s only a 250 but the performance is pretty poor. Right now, I wouldn’t recommend that someone buy one of these. If I keep it, I guess I better look at an extended warranty. I think I’ll need it.

Great looking bike really like the look.I switched from a 2007 to a 2009 .Awesome bike for dual purpose.So far I added a k&n filter,muzzy pipe,jet kit ,front 13 tooth sproket. Bike nows rocks,also the new dash instrumentation is awesome
