first time i saw kawasaki klx 150 was  awesome and the 250cc are more awesome, here the complete review of 2010 Kawasaki KLX250SF Review:

Engine
The KLX250SF powered by a compact liquid-cooled, 4-stroke engine, single cylinder. With the boring and stroke 72 x 61.2 mm, 249 cc engine move. A flat-top piston is combined with a combustion chamber provides compression ratio 11:1 pentroof. KLX250SF engine cylinder features electrofusion. Layers of ultra-hard in the aluminum cylinder subjected to offer superior heat transfer with light weight. Lightweight piston, piston pin and connecting rod enable higher revs.

Head valve DOHC 4-cylinder provide maximum valve area for optimum flow to boost low-end torque. 34 mm semi-flat slide CVK carburetor provides the optimal amount of fuel at all rpm, contributing to a sharp response, strong power, and fuel economy is excellent. A gear-driven balancing machine ensures smooth power delivery from idle to redline. On long trips, this means greater comfort and less rider fatigue. With electricity and starter Kawasaki Automatic Compression Release (KACR), which automatically picks up a valve at cranking rpm, start KLX250SF easy. Precise control of ignition timing, digital DC-current-powered Capacitor Discharge Ignition contributed to start easy and reliability in extreme conditions.

Dual high-capacity Denso radiators as used on our motocross bike KX provides superior cooling efficiency and contribute to space and weight savings. Very sleek and compact radiator cores and design features fins for excellent heat dispersion. Powerful three-phase alternator puts out 224 watts of power @ 5000 rpm. Environmentally friendly, a catalyser tube and secondary air injection system to ensure clean emissions. muffler equipped with spark arrester, meaning KLX250SF be able to access areas designated off-road.

Transmission ratio set the gear ratio closer to 6 gear ratios 5, facilitating the shift of overflows for increased performance. Modification of final drive ratio (42/14 – 39/14) matches the new ring road tires. Top gear reduced engine speed of about 100 rpm more than just 5000 rpm @ 100 km / h

Chassis

Frame and chassis components based on the KLX300R is the high level source KLX250SF-of performance. Chassis updates for improved road rideability SF and control. Wide, black coated, 36 spoke aluminum rims. KLX250SF box and the tubular steel frame high-tensile perimeter creates a package, a thin lightweight. The 25.5 ° and the steering head angle short wheelbase contribute to quick handling, while the high stiffness of the frame to ensure stability in a straight line.

Revised front suspension settings intensify road handling characteristics. 43 mm inverted front fork cartridge-style settings are equipped with the revised road to travel, springs, and 16-position compression damping adjustment. cartridges provide consistent damping force by minimizing aeration of the fork oil. 25 mm less travel for the stability of the road. Front fork travel: 255-230 mm. Fork guards to protect inner tube from the rocks and brush. Wide, black coated, 36 spoke, aluminum.

Front: 3,00-17, RK Excel
Rear: 4,00-17, RK Excel

Suitable performance tires IRC Road Winner:
Front: 110/70-17, RX-01F
Rear: 130/70-17, RX-01R

Union relations extracts reduce front-rear pitching motion, thus increasing the stability of the straight line and feels more planted on the corner. The nitrogen-filled remote reservoir rear shock has a 16-position compression and 8-position rebound damping and preload adjustment threadless. Revised settings for damping shock, spring, and complete the orientation of the road trip of more than KLX250SF. 25 mm rear travel is reduced to the stability of road.
Rear suspension travel: 230-205 mm.

Lightweight, highly rigid aluminum D-section suspension unsprung weight contributes to the decline. Suspension to allow for a wider selection of larger tires. KX-type chain adjusters allow racing proper adjustment of chain slack, helping to reduce the transfer of drivetrain power loss. new front disc brakes stopped offering impressive performance. A slide-pin, twin-piston caliper overcome the disc 300 mm semi-floating petal. Pin-slide, single-piston caliper operates the rear 240 mm petal disc.

treatment increased wheel stiffness radius of a thick (3.5 mm – 4.0 mm) contributes to lighter, smoother handling and offers greater durability for off-road ride. Digital instrument console-glance information. Dash features include a bar-graph tachometer, digital speedometer, digital clock, dual trip meter, and the neutral indicator light, the beam is too hot, tall, and turn signal. Front cowl and headlamp design provides KLX250SF an aggressive face. turn signal lens with clear sharpening Compact sporty styling.

On-street front fender contribute to the aggressive designs. Bright lights H4 (60/55W) provide safe lighting at night. Sealed, MF batteries reducing maintenance tasks. Seat shape using a rigid urethane so it’s easier to change seating position. Reduces seat height instill greater confidence for new riders and improve road handling. Seat height reduced 30mm (890mm -> 860mm). Off-road style rear fender of a two-piece construction. Tail light design provides enhanced visibility and contribute to KLX’s aggressive styling. Fast conversion front footrest gives the driver the option to ride the road surface of rubber and steel serrated for off-road
