Dual air vents help provide a stable fuel supply and eliminate hesitation, even when the bike is at extreme lean angles
Needle valve is suspended on a spring which acts like a shock absorber
Float is rubber instead of plastic
Close-Ratio TransmissionClose gear ratios help the acceleration performance of the KLX
Shift lever features a ball bearing like the KX™ models, to ease shifting and has a folding tip for less damage in a crash
Progressive Manual ClutchManual clutch offers young riders the chance to master clutch engagement and gear shifting
Spring damper in the clutch provides a 2-stage engagement that permits half-clutch use when riding at extremely low rpm or idling speeds and helps provide direct clutch feel and better durability

Rear brake uses a 186mm petal disc gripped by a 27mm single-piston caliper
Rear brake master cylinder features a large-volume, unitized reservoir that contributes to stable braking and helps ensure sufficient fluid pressure is maintained - even when the brake pad wears down
In addition to helping reduce unsprung weight, the wave shapes of the petal discs help clean the brake pads for more efficient braking performance
ErgonomicsCombination of the flat surface of the frames box-section, long footpegs mounted close to the bikes centerline and no kick-start lever add up to good grip and a high level of machine control available to the rider
Footpeg/frame relationship is modeled after the KX for maximum leg grip
