The single-most dominant motocross bike of the last decade.

Motocross was a sport enjoyed by Europeans for the most part of the time. Then the madness spread like wildfire and it was not long ago that it came to India as well. More and more people started entering the sport, for outright fun and competition.

By basic definition, motocross is a form of off-road motorcycle racing held on enclosed off-road circuits that boasts of terrain, uphill’s, downhill’s, corners, jumps, etc. It is a great spectator sport and equally challenging to compete in. The reason it is so good is because one gets the fine combination of thrills, excitement, colour, speed, strategy, endurance and above all smacking dirt. It offers the satisfaction and every man’s fascination with motors and wheels to which the traditional ‘stick and ball’ sports cannot respond to.

The Japanese manufacturer is all set to enter the Indian Motocross scene in a big way by offering two of their renowned machines that has dominated the Motocross scene across the globe. Kawasaki India already sells the KLX 110 dirt motorcycle priced at ₹ 2.65 lakh. It is powered by a single cylinder, air-cooled 112cc engine mated to a four-speed transmission.

The biggest guy in this story here is the all new Kawasaki KX 250f. It is hands down is the single-most dominant motocross bike of the last decade. But for some time now, the Blue Crew has grabbed some of the limelight. And for Kawasaki, who have captured 16 titles already with their 250 motorcycles, are in for a setup that can make the Blues a run for their money and reign the territories again.

For 2017, the KX250F has received a full makeover, with a new lighter chassis, improved suspension settings, increased power delivery, and comfortable slimmer ergonomics.

STYLING

Let’s face it, nobody buys a motocross motorbike for the way it looks or for the way it is designed. But, not many people know that for a fact that the these design elements and minimalistic bodywork keeps the motorcycle at the top of its game.

The 2017 model features slimmer shrouds as a result of revised radiators and their new orientation. You get a flatter everything including fuel tank and the seat with reinforced ribs. This combination of the new tank and seat aid in a more seamless design, which also makes it easy for riders to move around on top of the bike. And of course you get a bash plate. Overall, the look of the bike is similar to the elder brother, the 450F.

Making the motorcycle be even more compact is the aggressive new bodywork that features front and rear fenders, number plate and fork guards all falling in line together. Also creating a distinctive Kawasaki identity are black excel rims, black fork guards, and green highlights.

POWERTRAIN

For 2017, the Green team have given the 250f new redesigned engine with offset cylinder layout, for more efficient power and lighter piston designed by the company’s racing pedigree.

The power mill is tuned to suit the rider’s race experiences and boasts of a 249cc liquid-cooled, 4-stroke, single cylinder motor. It has a wide power band that focuses on high-rpm performance and is made to even extend into the over-rev rang. A 5-speed, return shift transmission takes the power to the rear via a chain drive. The motor provides 45 bhp and 27 Nm of peak torque. The motorcycle gets new exhaust header with integrated resonator maximizing throttle response.

Inside this power mill is where all the wizardry takes place. Taking cues from their racing departments, Kawasaki have made use of race-inspired tuning and parts like the high-performance bridged-box bottom piston to optimise combustion efficiency and help reduce friction. The cylinder has a new 7-degrees more forward offset that results in down draft-style intake routing which helps in having a more direct line to the combustion chamber. This eventually results in a stronger low end as well as an increase in maximum peak power.

Also, new innovations in fuel injection has led to a new imparted dual-injector fuel injection system that makes use on one injector facing downwards of the throttle valve and a second injector facing upwards close to the airbox. This ensures smooth, instant response featuring a finer atomization with four more spraying holes in addition to the existing four in the injector itself.

In an effort of the lightweight race, the pistons weigh 6 grams lighter and has a Molybdenum coating to reduce mechanical loss and reduce wear. Titanium valves, new exhaust camshafts, sprockets, slimmer cam chain, lighter 43mm throttle body and a lighter flywheel makes this a quick revving power house.

The lightweight ECU provides a wide variety of tuning from the factory and the rider can access three engine maps (standard, hard, soft). One can also opt for KX FI Calibration Kit (Handheld) that makes it a breeze to map your preferred settings on the go.

RIDE AND HANDLING

Talking about the business aspects of these machines, the 2017 model sees the return of the ERGO-FIT adjustable handlebars and footpegs. The adjustable handlebar mounts provide a choice of 4-positions (35mm range of adjustment) enabling the rider to set-up their ideal riding position. Factory-style Renthal handlebar and handlebar pads comes as standard. Two-position adjustable footpegs help reduce knee angle when seated.

A new 3mm narrower main beams and newly redesigned, lighter aluminium perimeter with a new front downtube have been optimised to obtain improved front end feel. All of these contribute to razor sharp cornering and superior handling while a flatter seat and new bodywork allow easier rider movement.

Suspension duties upfront are taken by Showa 48mm Separate Function Front Forks (SFF Type 2) with both damping and rebound adjustments that contribute to greater stability over braking and through corners. This has an improved fork action that provides sharp cornering and smooth, predictable front-end action through bumps and excellent stability when on landing jumps.

Out back the Uni-Trak rear suspension with Showa shock takes care of the damping with new linkage ratios and valve settings for an improved ride and feedback. The shocks make use of lighter springs and lower pitching effect, courtesy its lower rate. All this is mounted below the swingarm to maximize wheel travel and can be adjusted for a wide range of options. Self-lubricating alumite coating on the inner shock body improves wear resistance and shock action.

Given the racing experience and pedigree of the company, it is no surprise that this KX dons the 270mm petalstyle disc brakes in the front and the rear with dual and single piston callipers. Spoked 21" and 19" tyres sport Dunlop MX3s stubbed tyres.

To get you off the starting line/gate, Kawasaki has equipped the KX with Launch Control to maximize traction and acceleration. A tech reprised from the Kawasaki factory race team. It can be activated with just a push button which keeps assisting all the way into the first and second gearing and disengages itself as soon as you shift into the third gear.

Chassis Specifications

Suspension / Front 48mm inverted Showa SFF telescopic fork
Suspension / Rear Uni-Trak linkage system and Showa shock
Brakes / Front Single semi-floating 270mm Braking petal disc with dual-piston caliper
Brakes / Rear Single 240mm Braking petal disc with single-piston caliper
Tyres / Front 80/100-21
Tyres / Rear 100/90-19

PRICE

Since this KX will be bought to our shores through the Completely Built Unit (CBU) route, it will be a steep ₹6-7 lakh. It will be provided with the Lime Green colour only.

Accessories can also be purchased to level up the motorcycle’s capabilities. They include lever assemblies, KX FI Calibration Kit and green racing chain.

COMPETITION

Since the motocross scene in the country is still at a very nascent stage, not many options are made available to us. Yet, we have access to the Austrian KTM 250 XC-F. The 2016 KTM 250 XCF comes with new graphics, an air filter that can be switched out easily and quickly, and Neken handlebars. It also comes with a smaller front axle for reduced weight and increased trail and stability, while the front fork guards allow for quick maintenance, cleaning and are lighter than before.

KTM XC-F

The motor comes with a push button starter and the 4 valve, 4 stroke, DOHC 249 cc motor churns a peak power that is claimed to be 45 hp and 27 Nm. Power is transmitted through a semi-close-ratio six-speed gearbox, and redlines to an astonishing 14,000 rpm. The fuel injector is a Keihin system with a 44mm throttle body.

VERDICT

Entering a country where motocross is just a sport taken up by very few people compared to the mass, it is a gamble played by Kawasaki. And the fact that it is going to cost a bomb will shy away people even thinking of giving it a try. Hence, it is only safe to say that with this, Kawasaki will only cater to the professional few and to adventure groups running motocross activities.

The changes got into the motorcycle were a move in the right direction. A quick revving motor with traction control will steal the limelight out of any off – road motocross spec bike. The lighter and stiffer chassis is here to stay and it makes the motorcycle easier to ride and manoeuvre. And when it comes to competing against its cohorts, we have a strong reason to believe that the Green Team will bag top honours.

PRESS RELEASE

2017 KAWASAKI KX™250F

The new Kawasaki KX250F motorcycle packs more power, better handling and less weight to provide a bike that builds champions.

The Kawasaki KX250F is the single-most dominant motocross bike of the last decade. To keep riders
on the podium, Kawasaki introduces an all-new KX250F for 2017, in line with the updates of the KX™450F
motorcycle last year. The 2017 model offers a more powerful engine, a significantly lighter chassis, and slimmer
ergonomics, making this new model the fastest KX250F motorcycle yet.
The 2017 Kawasaki KX250F:
• Lighter weight (229.9 pounds)
• New more powerful and lighter engine
• New redesigned more narrow and lighter weight frame
• Improved clutch and shift feeling
• New flatter seat and a new lower/flatter tank, for improved handling and
ergonomics
This year’s KX250F is built with race-winning components to keep Kawasaki riders in that top spot at
the race track. From the showroom to the racetrack, the performance of Kawasaki’s KX family of motorcycles is
proof of its engineering pedigree. It truly is the bike that builds champions.
ENGINE
• New redesigned engine with offset cylinder layout, for more efficient power
• Lighter bridged-box bottom piston, designed from racing experience
• Downdraft-style intake layout with new injector angle designed for optimum
fuel atomization
• New downstream injector with twice as many holes, finer fuel droplets and
wider angle, resulting in stronger low-to-mid power and sharp response
• New and improved combustion chamber configuration
• New 43mm throttle body
2017 Kawasaki KX™250F press release, page 2 of 5
Tuned to best suit race-experienced riders, the 249cc liquid-cooled, 4-stroke single’s wide power-band
focuses on high-rpm performance that extends way into the over-rev. Highly acclaimed for its high output and
smooth power delivery, the 2017 model KX250F has race-inspired tuning and parts like the high-performance
bridged-box bottom piston and down draft-style intake routing. Mechanical friction is reduced thanks to things
like an offset cylinder—with increased forward lean angle—and plateau honing, resulting in a stronger low end
as well as an increase in maximum peak power. The connecting rod now features a journal bearing in lieu of a
needle bearing and items like the camshaft sprockets and chain have been revised along with a newly revised
exhaust camshaft, all factors resulting in more efficient power.
The KX250F dual-injector fuel injection system is a key component to its performance; introduced in
2012, it was the world’s first to be featured on a production motocross bike. Unlike a standard digital fuel
injection that uses one injector downstream of the throttle valve, the KX250F system uses a second, upstream
injector located close to the airbox. The downstream injector—redesigned for 2017—is used to help ensure
smooth, instant response featuring a finer atomization with more holes in the injector itself. The downstream
injector creates that stronger low-to-mid range power and quick throttle response, while the upstream injector is
charged with providing power.
As rpm and throttle position increase, primary operation switches from the downstream injector to the
upstream injector, depending on whether in a low (1st, 2nd) or high (3rd, 4th, 5th
) gear, the transition is gradual or
almost instantaneous. The upstream injector’s greater distance from the combustion chamber gives the fuel
particles and intake air more time to mix, as well as allowing the mixture to cool before entering the combustion
chamber, both of which contribute to more efficient filling, and ultimately more power.
The 2017 model also features revised ECU settings, along with a new exhaust system. The exhaust
header pipe is skinnier and shorter, resulting in improved performance.
TUNING
• Lightweight ECU, with revised settings
• Three engine maps (standard, hard, soft) contained in the ECU
• Optional KX FI Calibration Kit (Handheld) requires no tools, laptop or battery
The lightweight ECU of the KX250F motorcycle was designed specifically to withstand the rigors of
motocross racing, while still providing a wide variety of tuning. The Kawasaki KX250F provides three engine
maps that come pre-loaded into the motorcycle’s ECU that are easily accessible through the DFI® coupling
plug. These three color-coded couplers are designed to tune for hard, medium or soft track surfaces, and allow
riders to find the perfect power delivery for a particular terrain.
Using the optional KX FI Calibration Kit (Handheld), sold separately as a Kawasaki Genuine Accessory,
a rider can store and select from up to seven separate engine maps. The kit includes a portable handheld
calibration tool, which enables riders to make changes to the engine maps without the need of a PC, laptop or
battery, making it easy to tune at the track. It plugs in thanks to an additional harness not included in the kit.

FRAME & SUSPENSION
§ New Swingarm design with improved linkage ratio
§ Lighter weight and more rigid frame design
§ 6mm narrower frame design
§ Showa 48mm Separate Function Front Forks (SFF Type 2)
Changes for the KX250F start at the frame, with a newly redesigned, lighter aluminum perimeter with a
new front downtube and 3mm narrower main beams, for an overall reduction width of 6 mm. The frame rigidity
has been optimized to obtain improved front end feel.
Up front you’ll find Showa 48mm Separate Function Front Forks (SFF Type 2) with works-style internal
construction that locates its damping assembly in the left fork tube and a spring in the right. The Separate
Function Front Fork construction contributes to a planted feel at the front, superb damping performance and ride
comfort with greater bottoming resistance. It also has excellent stability when on the brakes or when landing
jumps. For 2017, revised settings contribute to greater stability over braking bumps and through corners.
The Uni-Trak® rear suspension with Showa shock now features revised valve settings and linkage
ratios, contributing to improved ride feel and traction and increased rear-end feedback. A lighter shock spring
this year means a weight savings, and the lower rate contributes to the reduced pitching effect over braking
bumps. The rear shock linkage mounts are below the swingarm to maximize wheel travel and the new linkage
geometry increases cornering stability. Dual compression with high and low speed adjustability offers a wide
range of tuning options. Self-lubricating alumite coating on the inner shock body improves wear resistance and
shock action.
STYLING & ERGONOMICS
§ Easier for the rider to change position while riding
§ Integrated bodywork for seamless rider interface
§ Aggressive KX body work and in-mold graphics
The all-new minimalist bodywork includes slimmer shrouds, thanks to the revised radiators and their
new orientation. The KX250F now features a new flatter and larger capacity fuel tank, along with a new flatter
seat with reinforcing ribs. The combination of the new tank and seat aid in a more seamless design, which also
makes it easy for riders to move around on top of the bike.
Aggressive all-new bodywork, which includes front and rear fenders, number plate and fork guards,
makes the bike look more compact and is complemented by factory-style design and Kawasaki’s first in-mold
graphics on the radiator shrouds. Black Excel rims, black fork guards, and green highlights help create a
distinctive Kawasaki identity.
Returning this year are ERGO-FIT™ adjustable handlebars and footpegs to better suit riding styles and
different rider statures. The handlebars have four position options and the footpegs have two placements
available.

LAUNCH CONTROL
For pro riders and amateur riders alike, the KX Launch Control is a major advantage in getting out of the
starting gate straight and fast. Launch Control Mode has the greatest effect within the first few seconds of
releasing the clutch off the start.
The KX250F features a Launch Control system that, with the simple press of a button, allows riders to
activate a separate engine map designed to assist starting in certain conditions. The Launch Control Mode map
retards ignition timing, allowing tires to gain grip in low-traction situations, and allowing riders to focus on their
lines. Launch Control remains active through first and second gear, until the rider shifts into third gear, and then
it returns to normal engine timing.
Even for top-level riders, controlling the hard-hitting power of a KX250F motocrosser off the start requires
a high degree of throttle control and clutch finesse. By optimizing this power, Launch Control Mode helps riders
maximize traction, increasing the chance of getting a good start.
BRAKES
Contributing to the racing components found throughout the KX250F are the brakes, with 270mm petalstyle
disc brakes in the front. These brakes deliver strong braking force and superb control. The petal style discs
contribute to both sporty looks and a high-quality appearance. Rear caliper guard protects the caliper from
damage.
