The 2021 Kawasaki KLX 140R, 140R L, and 110R F dirt bikes are designed to be progressively used by teenaged riders to progress through to full sized off-road bikes. Powered by a 144cc air cooled, four-stroke single, all three variations of the bike share a five speed manual transmission and a light but positive clutch.

The KLX 140R is the base spec of the three and is aimed at the 10-14 year old rider with a low seat height and smaller wheels. It features disc brakes front and rear, an electric starter, and a full 7 inches of suspension travel.

The KLX 140R L from the Japanese manufacturer is the mid-spec, designed for 13-15 year olds. The only major difference from the base spec is larger wheels, with 19 inches at the front and 16 inches at the rear. It shares the same suspension movement of the base spec at 7.1 inches.

The Kawasaki KX110R F is the “big boy” bike of the lineup for fully grown young teens at 16+ years old, featuring full sized wheels and adjustable suspension. The front wheel is 21 inches, the rear is 18 inches, and the suspension can be adjusted to provide up to 7.5 inches of travel, and is meant to be the transition bike to more powerful or larger trail or off-road bikes.

The 2021 Kawasaki KLX 140R starts at $3,149 USD / $3,849 CAD,

The KLX 140R L starts at $3,449 USD / $4,249 CAD

The KLX 140R F starts at $3,749 USD / $4,449 CAD.
