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
