The End of an Era: Carburettors Out, Fuel Injection In

The announcement of the 2022 Kawasaki KLR650 sent ripples of excitement through the motorcycle community, primarily due to one monumental change: the introduction of electronic Fuel Injection. This update finally propelled the KLR650 into the 21st century, addressing one of the most frequently discussed aspects of its predecessor. For years, the KLR's carburettor, while simple and reliable in its own right, presented challenges in certain conditions. Riders often wrestled with cold starts, particularly in chilly climates or at high altitudes where the air-fuel mixture could become temperamental. The new fuel-injected system promises to banish these frustrations, offering consistent performance and effortless starting regardless of environmental variables. This isn't just a minor tweak; it's a fundamental shift in the KLR's character, aiming to make it even more accessible and dependable for a wider range of riders and adventures.

A Closer Look at the New Fuel Injection System

Kawasaki has engineered the new fuel injection system to be both sophisticated and practical, aligning with the KLR’s ethos. At its heart is a 10-hole, fine-atomising fuel injector designed to spray incredibly precise 60 µm droplets. This fine mist ensures a far more efficient air-fuel combustion process compared to a carburettor, leading to several tangible benefits. Firstly, it significantly enhances fuel efficiency, allowing riders to squeeze more miles out of each tank. Secondly, it contributes to cleaner exhaust emissions, helping the KLR650 meet modern environmental regulations without compromising performance. Furthermore, the system incorporates an oxygen sensor that provides continuous feedback to the engine's control unit. This closed-loop system allows for real-time adjustments to the fuel delivery, optimising performance across varying speeds, loads, and atmospheric conditions. This level of precision was simply unattainable with the previous carburettor, making the new KLR650 a more refined and responsive machine for both daily commuting and long-distance exploration.

The practical implications for riders are substantial. Gone are the days of fiddling with a choke or struggling with a reluctant engine on a frosty morning. The electric start, combined with the self-adjusting fuel injection, ensures instant ignition and smooth running from the moment you thumb the starter button. For those venturing into mountainous regions, the KLR’s newfound ability to automatically compensate for changes in altitude is a game-changer, maintaining optimal performance where carburetted bikes would often gasp for air. This enhanced reliability and ease of use truly solidify the KLR650's reputation as a dependable workhorse, ready for whatever the road – or lack thereof – throws at it.

Beyond Fuel: Engine Enhancements for the Modern KLR

While fuel injection is undoubtedly the headline act, Kawasaki didn't stop there. The 652cc liquid-cooled, four-stroke, single-cylinder engine, renowned for its bulletproof nature, received a host of other refinements to complement the new fuel delivery system. Revised intake and exhaust cam profiles have been carefully selected to improve mid-range power and torque characteristics. This means a more usable powerband for everyday riding, making overtakes safer and navigating tricky off-road sections easier. The exhaust pipe diameter has also been subtly reduced by 7.7mm, further contributing to this improved mid-range grunt.

Reliability, always a KLR strong suit, has been further bolstered with a stronger cam chain guide material and shape. Gear shifting, too, has seen improvements, with clutch release bearings changed from ball to thrust-needle bearings, and revisions to the gear dogs and shift fork on third gear, alongside a new finishing treatment for fourth and fifth gears. These seemingly minor updates contribute to a smoother, more positive gear change feel. Furthermore, the 2022 model benefits from a new sealed, low-maintenance battery that is significantly lighter than its predecessor. Lighter starter, ignition coil, and evaporator canister components also shave off precious grams, while a new honeycomb catalyser works in conjunction with the oxygen sensor for even cleaner emissions. These comprehensive engine updates ensure the KLR650 remains true to its heritage of durability while embracing modern performance standards.

Does the new KLR have a fuel injection system?
The fuel injection system in the new KLR isVERY basic, you might be able to fatten the fuel curve, but without advancing the timing you are limited. The new bike still uses the CDI for spark. A well tuned carburetor will perform better. Fattening the fuel curve may or may not increase power slightly, but fuel mileage WILL Usually be reduced.

Chassis and Suspension: A More Planted Ride

Beyond the engine, Kawasaki implemented significant chassis upgrades to enhance the KLR650's handling and comfort. While retaining the proven semi-double-cradle frame, the rear frame is now integrated with the main frame, resulting in increased torsional rigidity. This translates to a more stable and predictable ride, especially when fully loaded or tackling rough terrain. A 30mm longer swingarm with a 2mm larger diameter swingarm pivot shaft further contributes to improved handling and stability. Both front and rear suspension settings have been revised to complement the new frame and weight, providing a more planted feel. The 41mm front forks, offering 200mm of travel, feature firmer springs to improve bump compliance, reduce front-end dive under heavy braking, and resist bottoming out. The adjustable Uni-Trak rear suspension, with 185mm of travel, is also firmer to accommodate heavier loads and luggage, while rear spring preload and rebound damping are adjustable, allowing riders to fine-tune the setup for specific conditions or preferences. These enhancements ensure the KLR650 remains a capable dual-sport machine, equally at home on tarmac and trails.

Braking Power and Safety: Stopping with Confidence

With an updated engine and chassis, improved braking was a logical next step. The 2022 KLR650 boasts a larger 300mm front brake disc, replacing the previous petal-type with a round rotor, for significantly greater stopping power. The rear brake disc is also slightly thicker to improve heat dissipation under heavy use and is now round as well. Crucially, Kawasaki offers models with and without ABS, providing riders with the choice that best suits their riding style and intended use. While ABS offers enhanced safety on paved roads, many off-road riders prefer the ability to lock up the wheels for better control in loose conditions. The KLR650 comes equipped with a 21-inch front wheel and a 17-inch rear wheel, both featuring stronger rims and larger-diameter axles for increased durability. The tube-type tyres also make roadside repairs more manageable, a nod to the bike's adventure touring pedigree.

Rider Comfort and Practicality: Ergonomics Reimagined

The KLR650 has always been known for its upright, comfortable riding position, and Kawasaki has refined this further for 2022 to deliver a stress-free experience on longer adventures. Anti-vibration rubber mounts have been added to the handlebars, and the footpegs, also featuring rubber inserts, have been moved 10mm outwards, reducing fatigue on extended rides. The new fuel tank design not only contributes to the bike's updated aesthetics but also provides a more natural fit for the rider’s knees, enhancing comfort and control. Although the tank's overall volume remains the same, a redesign combined with the new fuel pump that draws from the very bottom of the tank increases the usable fuel volume, contributing to an even longer riding range. A taller windshield, now 50mm higher than the previous model and with two-position adjustability (offering a further 30mm), provides better wind protection. The seat has been revised with thicker, firmer urethane and rubber dampers underneath for improved rider comfort, and passenger grab bars have been reshaped. Even the side stand has been shortened by 30mm, making it easier to deploy while on the bike.

Modern Touches: Digital Display and LED Lighting

Bringing the KLR650 firmly into the modern era are its updated aesthetics and technology. A new, brighter LED headlight vastly improves nighttime visibility, while new taillight and turn signal designs contribute to the refreshed look. Longer mirror arms also enhance the rearward view.
