Kawasaki Ninja 250SL 2018

Super Sports Single

Kawasaki’s newest entry into the 250cc full-fairing sport arena is the Kawasaki Ninja 250 SL (SuperLight). Powered by a 4-stroke Single cylinder engine mounted in an original trellis frame, the newest Ninja offers sporty fun in a slim, lightweight and compact package. Great performance, quick, nimble handling and aggressive styling.

The fuel-injected 249 cc liquid-cooled, 4-stroke, single delivers smooth, responsive power at low and medium rpm and hard-hitting power at high rpm giving the rider an exciting and exhilarating ride.

The Kawasaki Ninja 250SL features an all-new trellis frame. The size of each component of the frame was carefully selected to ensure a slim package with a nimbleness similar to that of other larger Ninja RR models.

Like all other Ninjas in the range, the new Ninja 250SL has a very sporty and stylish full-fairing. It’s slim supersport styling ensures the Ninja 250SL stands out. All components were all designed to be as compact as possible and are mounted as close as possible to the trellis frame to keep the bikes slim design and sporting nature.

The ethos behind both this and the Kawasaki Z250SL was to live true to the name. Superlight by name, Superlight by nature. Thus achieving ease of use with amazing agility. These characteristics not only boost confidence in the machines ability but offers an easy and pleasurable ride.

Whether you are looking for a commuter or a weekend toy, the Kawasaki Ninja 250 SL will appeal to a huge range of riders.

Kawasaki warrants products with extended warranty to be free of manufacturing defects for an additional 24 months from the expiry date of the original manufacturer's warranty. The following products can be covered for private use* only:

Street-legal Motorcycles**

* Private use - a private user is defined as "any person who is acting for purposes which are not related to his trade, business or profession".

Warranty Terms and Conditions

If, within the extended warranty period, a failure occurs which is determined by Kawasaki to be caused by a manufacturing defect, Kawasaki will, at its discretion, arrange for the repair or replacement of the necessary parts at no cost to the customer. This can be carried out by any authorised Kawasaki Dealer. However, it is recommended that repairs and servicing are done by the original selling dealer who has a full history and knowledge of each product they have sold.

Note the following terms used throughout this document:

  • 'Kawasaki' = Kawasaki Motors Europe N.V.
  • 'Dealer' = Official Kawasaki dealer authorised for the relevant product group.

This warranty contains obligations and exclusions solely on the part of Kawasaki Motors Europe N.V. and not on the part of any dealer.

Nothing in this document shall be construed as an agency between Kawasaki and any of its authorised dealers or their staff.

  • This warranty is only valid within European countries, which have official Kawasaki authorised representation for the product(s) concerned.

Warranty Exclusions

Kawasaki will not accept responsibility if, in its sole opinion, the part or parts require repair or replacement as a direct result of:

a) Alteration from standard specification in a manner, which affects the performance, durability or safety of the product or any of its component parts or genuine Kawasaki accessories, e.g.:

  1. The fitting of non-genuine Kawasaki parts or accessories, unless these are recommended or approved in writing by Kawasaki;
  2. Modifications or adjustments not recommended or approved in writing by Kawasaki.

b) The use of lubricating oils, fuel or other fluids (including cleaning materials) which are not in accordance with the recommendations contained in the owner's manual.

The warranty does not cover routine service adjustment or normal replacement of service items (such as oils, fluids, spark plugs and filters), or wear and tear items (such as batteries, brake and clutch friction materials, drive chains or belts and tyres, cables and bearings). However, such items are covered if replacement is required as a direct result of a manufacturing or material defect.

e) Any competitive racing or related use.

f) Any damage or consequential damage caused by accident or by owner's or operator's neglect or abuse.

g) Improper storage or deterioration from the elements.

The warranty may not apply if:

i) The periodic maintenance and servicing is not carried out by an authorised Kawasaki dealer at the appropriate intervals specified in the relevant owner's manual. Evidence of this servicing must be produced, if requested, at the time of any warranty claim. It is the owner's responsibility to ensure the service record book is kept up to date by the servicing dealer. It is advisable also to keep copies of any service or repair invoices in case the book is lost.

ii) Any problem experienced is not reported to a Kawasaki Dealer within a reasonable time or the motorcycle is not properly inspected by that dealer. The owner should take all possible steps to prevent further damage as soon as any problem is apparent. Any consequential damage that is caused by the continued use of the product after a problem has been identified may not be covered by this warranty.

The warranty covers private use only. The warranty will not apply if the unit is used for any business or commercial purpose.

The following items are not covered:

Aggressive Ninja supersport styling

Like the other Ninjas in the series, the Ninja 250SL features seductive, full-fairing bodywork. Complementing its slim package, the contrast between its flared and waisted sections gives it a dynamic, hourglass figure. Aggressive single-bulb headlamp contributes to the lightweight image, and with the sharp windscreen and sporty wheels, gives this new Ninja a serious supersport look. 

All-digital Instrumentation

All-digital instrument panel gives the cockpit a modern, racy look.

Supersport Ergonomics

A slim overall package, tight-fit full-fairing bodywork and low clip-on handlebars put the rider in an ideal position for aggressive, sporty riding

Lightweight Wheels with Slim Tyres

Sporty Ninja-style wheels are fitted with slim tyres chosen for their contribution to the bike’s nimble handling.

Original Trellis Frame

Trellis frame enables a slim, lightweight and compact package as well as contributing to nimble handling.

249 cm3 Liquid-cooled, 4-stroke Single

Offering quick-revving sporty performance in a slim, lightweight and compact package, the single-cylinder engine delivers smooth, responsive power at low and medium rpm and hardhitting power at high rpm.

Uni-Trak Rear Suspension

Kawasaki’s original linkage-equipped Uni-Trak rear suspension delivers a smooth ride and stable handling over a wide range of speeds and road conditions.

37 mm Telescopic Fork

37 mm telescopic contributes to both light, nimble handling as well as riding stability.

Lightweight Chassis

At 151 kg, the Ninja 250SL is more than 20 kg lighter than the Ninja 250. The light weight is a significant factor in the bike’s nimble handling.

Petal Disc Brakes

Petal disc brakes front and rear deliver strong, easy-to control stopping power and add to sporty looks.


Sudden over-application of the brakes, or braking on low-grip surfaces (surfaces with a low coefficient of friction) such as wet asphalt or manhole covers may cause a motorcycle's wheel(s) to lock up and slip. ABS was developed to prevent such incidents. Kawasaki ABS systems are controlled by high precision and highly reliable programming formulated based on thorough testing of numerous riding situations. By ensuring stable braking performance, they offer rider reassurance that contributes to greater riding enjoyment.
