2021 Kawasaki KLX Lineup First Look: KLX140R and KLX140R L Debut

The first three 2021 Kawasaki KLX off-road motorcycles have been revealed. While there are no mechanical changes, Kawasaki has updated the model designations of two of its KLX140s. To match up the nomenclature with the larger KLXes, the basic 140 is now the 2021 Kawasaki KLX140R (an R has been added). The 140 with the 16-/19-inch wheel combo is renamed the 2021 Kawasaki KLX140R L (formerly the KLX140L). Returning with updated graphics is the 2021 Kawasaki KLX230R, which successfully debuted last year. Let’s take a quick look at this trio of 2021 Kawasaki KLX models.

This is a full-sized trail bike that will still appeal to smaller riders. With a 21-/18-inch wheel combination, the KLX230R is ready for the toughest trails. The fuel-injected 223cc air-cooled motor isn’t especially fast, but it is torquey and quite capable on single-track trails. Kawasaki matched the KLX230R’s suspension to its engine, so the action is soft and enjoyable for trail riding. The 36.2-inch seat height will attract riders with shorter inseams, and they will appreciate the modest 254-pound weight—except in California where tailpipe sniffing bureaucrats bump the weight up to 262 pounds. The 2021 Kawasaki KLX230R is a fun and well-balanced off-road motorcycle.

When a youngster outgrows the auto-clutch 110s of the trailbike world, they can graduate to the 2021 Kawasaki KLX140R. That means they get a five-speed transmission with a manual clutch, along with the bigger wheels (14-inch/17-inch) and additional displacement. Suspension travel is over seven inches, and there is over nine inches of ground clearance. That means the younger rider can access more of the adult trails without getting frustrated. The seat height on the 2021 Kawasaki KLX140R in an unintimidating 30.7 inches.

Smaller adults will appreciate the 2021 Kawasaki KLX140R L. The L means larger wheels (16-/19-inches) and a fully adjustable piggyback reservoir shock—suspension travel at both ends is unchanged. The ground clearance is bumped up to 10 inches, the wheelbase extends an inch, and the seat height rises to 31.5 inches. While the ergonomics are unchanged, the larger wheels make the 2021 Kawasaki KLX140R L easier to ride on rockier trails.

We’re happy to see these three KLXes, and expect to see more models in the 2021 Kawasaki KLX lineup before the year is out.
