They say that variety is the spice of life and when it comes to riding motorcycles, truer words have never been spoken. We’d all love to see our garages crammed full as a TV chef’s spice racks, but that just isn’t a reality for most riders — outfitting a garage gets a lot more spendy than buying spices. Thankfully, an affordably priced dual-sport like the 2021 Kawasaki KLX300 gets the seasoning right for those who’d like to sample a heaping helping of riding. 

With an MSRP of $5,599 for the quintessential Kawi Lime Green trim and a couple-hundred smackers more for the Fragment Camo livery, the entry-level KLX300 — along with its KLX300SM supermoto (MSRP $5,999) that we also tested — fills a crucial part of Kawasaki’s off-road lineup, providing a financially accessible entry point to the wide world of motorcycles. Street-legal and off-road-ready, dual-sport bikes are perfect for riders that want to get out and taste-test a little bit of everything. Plenty of newly minted motorcyclists have cut their teeth on lower-displacement dual-sport machines like the KLX300, finding the versatility quite appealing. Dart around suburbia, head to the trails and fill in the gaps with some economical local commuting. Not a bad deal, eh? Especially since building dirt-riding skills is the fast-track to improving street-riding expertise.

This year Kawasaki’s KLX300 received a nice boost in power thanks to a larger, 292cc DOHC liquid-cooled four-valve engine. It’s a motor with a happy-go-lucky personality you can’t help but adore. Compared to the KLX250 that the KLX300 replaces, the new steed’s fuel-injected single-cylinder powerplant is punched out 6mm, increasing the bore to 78mm while retaining its 61.2mm stroke. The 34mm throttle body carries over and the compression ratio picks up a skosh to 11.1:1. It also uses more aggressive cam profiles, making it livelier than its predecessor. All of that is paired to a 6-speed gearbox and 14/40 final drive. If all of those engine specs seem similar to the mill found in the green-sticker-legal KLX300R off-road bike, that’s because it is — lock, stock and barrel.

We took to the sweeping streets of Folsom, California aboard the new KLX300 and bounced around plenty of fire roads before adventuring into the off-road wonderland of Prairie City SVRA where we could really check out its off-road chops. Hit the electric start and you’re met with a quiet pitter-patter that will never upset the relationship with your neighbors. Thanks to EFI, you won’t have to deal with the notoriously cold-blooded mannerisms of the pre-2014 carbureted KLX250.

The KLX300’s 292cc single-cylinder engine is sourced from the Kawasaki KLX300R off-roader.

No matter the setting, the KLX300 produces enough get-up-and-go to satisfy most riders, reaching speeds into the eighties without becoming a rattily mess. It churns out a healthy dose of bottom-end torque and good midrange power that’s just as handy when zipping through city streets, as it is on the trail. If you wring its neck on freeway long hauls, you will feel some vibes come through, but power flattens out up top anyway. Combine all those traits with near-perfect fueling and you net power delivery that’s fun, linear and extremely predicable.

Better yet, we’re talking about accessible, real-world every-rider power here, folks. The KLX300 isn’t a fire-breathing dual-sport from Europe that’s little more than a high-strung MX machine with lights; this bike feels accommodating for new riders and engaging enough for salty veterans alike. As awesome as the Euro dual-sports may be, they’re aimed at a more hardcore clientele and come at a much steeper price.

21- and 18-inch wheels don’t slow the KLX300 down too much and the Dunlop D605 intermediate rubber grips well on- or off-road.

The 6-speed gearbox is spaced well for on- and off-road riding and coupled with the 14/40 final drive ratio, Kawasaki hit a sweet-spot for riders rolling on public roads to the trail. Initial gears are lower and great when exploring trails, while the upper range of the gearbox matches well with faster city streets or highway riding. The shift throw feels light, and while I’d like a little more positive engagement, that’s a minor quibble. Add in an extremely light clutch pull and you have a friendly package. 

The sturdy bones of the KLX250 date all the way back to 2006 and the KLX300 utilizes the same basic chassis. Despite their age, the steel perimeter frame and aluminum swingarm perform admirably, pairing well with the level of engine performance on tap.

The LCD instrument panel is basic and provides just about everything you’d at a quick glance. A gear indicator would be nice on future models.

The short 56.7-inch wheelbase imbues the KLX with a whippy personality, letting riders aim it in any direction without much effort. It’s an uncomplicated affair when peeling into a paved canyon road or while tip-toeing through a rock garden. Give the footpegs some input and the KLX does exactly as it’s told; it’s that simple.

Equipped with off-road ready 21- and 18-inch wheels, as well as Dunlop D605 tires, you will have to respect their lean angle limits on the street (a truism for dual-sports overall), but there’s plenty of grip. KLX tracks true and doesn’t suffer from headshake or front-end nervousness at high speed, reinforcing its accommodating disposition.

Consider also the 43mm USD fork with adjustable compression damping and the fully adjustable gas-charged Uni-Trak shock — respectable amenities at this price point. With 10 inches of travel in the front and 9.1 inches in the rear, you have a solid package for soaking up bumps and thumps, regardless of the environment. On urban jaunts, the soft suspension setup gobbles up anything mean city streets can muster. Out on the trail, the suspension holds its own and that soft setup won’t hamper your dirt riding ambitions — it’s Cadillac cushy and offers loads of comfort, yet remains remarkably competent. If you get frisky and jump a little too high or rail some rough high-speed sections with too much zest, you may meet the bump-stops, but even in those situations, the KLX doesn’t get out of shape. Plus, the 10.8 inches of ground clearance and an integrated bash guard are on hand, just in case.

The plushy ride pays off in light of the tall 35.2-inch seat height. A rider of my size will create a decent amount of sag, which allows my 32-inch inseam to reach the deck easily. Shorter riders may need to sidesaddle at stops or be on tiptoes, but the 302-pound wet weight makes riding or picking this bike up (hey, trail mishaps happen) unintimidating. The ergonomics work well for standing or sitting and the long bench saddle allows a lot of rider movement.

The KLX300 is stable, forgiving and compliant, which makes it particularly suited or helping newer riders learn the ropes.

In the braking department, a 2-piston caliper and 250mm rotor up front work along with a 1-piston caliper and a 240mm rotor in back. Both deliver adequate stopping power on road and could benefit from more feel, but that’s an expected tradeoff given its multipurpose DNA. Change scenery, and the soft initial bite and progressive brake action work well in low-grip situations often encountered in off-road use and feel at the lever is just right. It’s all a compromise for sure; but it’s a good, well-balanced compromise.

And so it is with this bike on the whole. Arguably, entry-level machines in the market carry the most difficult job. Building products to a price point while also making them accommodating to a wide variety of rider sizes and skill levels is no easy task. But Kawasaki seems to have cleared these hurdles with ease. Given its impressive performance creds, the 2021 Kawasaki KLX300 wears its entry-level title like a badge of honor: This is one affordable all-rounder that’s also an eminently capable ride.

    • They rarely give those numbers and when they do they’re very suspect. The old KLX250S makes about 18 rwhp, so I’m guessing this one makes about 21 rwhp.
      It good to see the power increased on this new model, but they didn’t go far enough. I’m looking for 400cc’s minimum. Til’ then I’ll keep my old 250.

  1. klx 300r makes 34 hp about 5hp shy of the kx250f race bike, it does extremely well in the trails andd in offroad racing i raced mine in enduro series and won my class first time out, while the majority of the race bikes were hung up in the rock sections this bike excelled, and although the drz400 pulled me off the start to the first turn, once we hit the trails and rock sextions this bike excelled over the drz and a ktm in the class, after i hit the rock section i never seen either bike agian in the 2 hour race..bike is like a mountain goat, the only thing id change is the tires they are a little hard and id go with a michelin star cross…but the electric start and short stature coupled with the virtually mainteance free engine, makes this bike a good choice over the race bike with continuous maintenance and only 5 hp difference

    • Thanks for the comments, doing some additional research after the fact.. I just bought a KLR650 last month, and actually was looking for something more like the KLX300. I know totally different uses..But I have done a ton of Car Overlanding and dirt biking as a kid. I originally went looking for a KLX300 type bike and was just drawn to the KLR. I always planned to get two bikes one for me and my son. so I just left a dealership in Denver and gave a deposit on the KLX. 2 always better than on!
