Kawasaki KLX300R

The adult beginner dirt bike market has held steady for many years, but there hasn't been much innovation or competition among the manufacturers. All that changed a few years ago when Kawasaki introduced the KLX140G, and the bike's popularity indicated there was a vastly untapped market for full-size adult beginner dirt bikes. In 2020 Kawasaki introduced not just one, but two new adult beginner dirt bikes to their KLX lineup - the KLX230R and the KLX300R. In this article, we'll take a look at the 2020 KLX300R.

Kawasaki KLX300R

The 2020 KLX300R is being marketed as a bike that bridges the gap between a weekend play bike and a full-on race bike and that's a good description. It's always helpful to compare one bike to another, but only if you can compare apples to apples. Like the KLX140G, the KLX300R doesn't have any direct competitor. The closest competitor in the beginner class would be the Honda CRF250F, and in the competition class, Honda's CRF250RX or Yamaha's WR250F would be the next step up, but it's a big step up. A few similarities (and differences) between the bikes will be noted, but this isn't a full-on KLX300R vs. CRF250F vs. WR250F article.

KLX300R features:

The KLX300R is the largest adult-size beginner dirt bike and has some features that the other beginner bikes don't have. The KLX300R has the largest engine (292cc) in the beginner bike class and is the only bike that has a DOHC engine. The 300R is also the only beginner bike that's liquid-cooled instead of air-cooled. There's nothing wrong with an air-cooled bike, but higher-end performance bikes are all liquid-cooled. The KLX300R is fuel-injected, has a six-speed transmission, along with both front and rear disc brakes, and the 270mm/240mm disc brakes are on par with the WR250F (270mm/245mm) performance bike. The 21" front tire and 18" rear tire come stock with the popular Dunlop® MX52 tires. There's an electric start, but no backup kickstarter.

The seat height of the 300R is 36.4" which falls about midway between the CRF250F (34.8") and the WR250F (37.6"), so the 300R will fit a wide range of adult riders, and the KLX300R handlebar offers a four-way ERGO-FIT® adjustment similar to the Honda CRF250F. The 300R has a spark arrestor and low-fuel warning light, as does the CRF250F. The image below shows the KLX300R ERGO-FIT® handlebars (image courtesy of Kawasaki).

The 12.0" ground clearance coupled with the generous 11.2" of rear travel allows the 300R to handle more aggressive riding on a variety of terrains. The rear travel on the CRF250F is 9" and the WR250F rear travel is 12.5", so the 300R once again falls (roughly) midway between the two bikes.

The KLX300R weighs 282 pounds so it's the heaviest beginner bike, but that's understandable given the larger engine size and larger gas tank (bike weight is calculated 'ready-to-ride', with all fluids added). The KLX300R is 17 pounds heavier than the Honda, and 28 pounds heavier than the Yamaha. Keeping in mind of course that the WR250F is more of a performance bike so it uses a different, lighter (and more expensive) frame.

Both the Honda CRF250F and Kawasaki KLX300R offer a six-month warranty with the option to extend the warranty at an additional cost. The Yamaha WR250F offers a 30-day warranty which can also be extended at an additional cost.


Here are some of the specs for the three bikes:

2020 Honda CRF250F

  • Transmission: Five-speed
  • Rear travel: 9"
  • Seat height: 34.8"
  • Ground clearance: 11.3"
  • Fuel capacity: 1.6 gallons
  • Weight 265.0 lb.
  • MSRP: $4599
2020 Kawasaki KLX300R
  • Engine: 292cc DOHC liquid-cooled
  • Transmission: Six-speed
  • Rear travel: 11.2"
  • Seat height: 36.4"
  • Ground clearance: 12.0"
  • Fuel capacity: 2.1 gallons
  • Weight 282.2 lb.
  • MSRP: $5499
2020 Yamaha WR250F
  • Engine: 250cc DOHC liquid-cooled
  • Transmission: Six-speed
  • Rear travel: 12.5"
  • Seat height: 37.5"
  • Ground clearance: 12.6"
  • Fuel capacity: 2.2 gallons
  • Weight 254.0 lb.
  • MSRP: $8599


The brand new 2020 Honda CRF250F is a great full-size beginner bike that has already established itself as a solid performer after only a year on the market, and it's the most affordable choice of the new breed of adult beginner dirt bikes.

The KLX300R raises the bar for other beginner dirt bikes by offering a larger DOHC liquid-cooled engine, larger fuel tank, and plenty of rear wheel travel, but it also raise the price tag by $900 compared to the Honda CRF250F. The KLX300R doesn't have the bells and whistles of the WR250F such as a headlight and instrument panel, but the 300R doesn't have an $8599 price tag either.

Kawasaki hit the nail square on the head with the smaller KLX140G a few years ago, and it looks like they're going to do the same with the KLX300R. It's great that consumers have more beginner dirt bike choices, and the KLX300R is a good choice for beginning riders who have enough confidence in their riding abilities to handle a bike with more power, or someone who has outgrown a smaller bikes and is ready to step up, without breaking the bank.
