The 2021 KX250 is Kawasaki's first 250 motocross bike with electric start
The 2021 KX250 is a significant upgrade from Kawasaki, which has spent time, money and energy making improvements that have been asked for by its customers. The 2021 KX250 is Kawasaki's first 250 motocross bike with an electric start, which is a notable addition to the bike's capabilities. The electric start is activated by the push of a button located on the handlebar near the right grip, making it easy and convenient to use. This feature is especially useful in intense race situations, where a quick restart can mean the difference between keeping your lead and falling behind.
The 2021 KX250 also features a new high-capacity coned disk-spring clutch, also known as a Belleville washer spring, which has been used on KTM and Husqvarna clutches for years. This new clutch offers a more direct feel and an easier pull for lighter lever action, reducing rider fatigue while on the racetrack. The intake on the new model has also been slightly smoothed and lengthened, making a difference on the track despite minimal changes in appearance.
The 2021 KX250's engine has been updated to deliver even more power, making it the most powerful KX250 to date. The new piston head is more flat-topped, increasing compression and allowing the new engine to rev up to 14,500 RPMs, 250 RPMs higher than the previous year's model. The bike's nimble handling has also been improved, with the popular KX450 frame now surrounding the smaller engine, making the bike comfortable to ride.
The 2021 KX250 is an all-new model with a price point of $8,299, which is competitive when compared to other brands. The bike comes with Dunlop MX3S tires and is available in dealers. The KX250 has more AMA motocross and supercross championships combined than any other manufacturer in its class, and the 2021 model looks to continue this winning history with its impressive list of enhancements.

The electric start is powered by a lightweight, compact lithium-ion battery
The 2021 Kawasaki KX250 is the manufacturer's first 250 motocross bike with an electric start. This feature is powered by a lightweight, compact lithium-ion battery, which helps keep the weight of the bike down. The electric start is activated by the push of a button located on the handlebar near the right grip, making starting the bike easy and convenient. This is a significant improvement over the previous kickstarter, which has now been removed.
The lithium-ion battery that powers the electric start is known for its high energy density and compact size. This makes it ideal for use in the KX250, as it helps to keep the weight of the bike down while still providing sufficient power for the electric start and other electrical systems. The lightweight nature of the battery also contributes to the overall agility and performance of the bike.
Lithium-ion batteries are known for their high power-to-weight ratio, which means they can provide a significant amount of energy while remaining relatively light in weight. This is crucial in a motocross bike like the KX250, where weight and handling are critical factors in performance. The compact size of the battery also allows it to be neatly integrated into the bike's design without adding bulk.
In addition to the electric start, the lithium-ion battery also powers the KX250's EFI (Electronic Fuel Injection) system. This system ensures precise fuel delivery and ignition timing, resulting in improved engine performance and fuel efficiency. The combination of electric start and EFI system contributes to the overall responsiveness and power of the KX250.
The use of a lithium-ion battery in the KX250 is a significant upgrade over traditional lead-acid batteries. Lithium-ion batteries offer several advantages, including higher energy density, lower self-discharge rates, and longer lifespan. They are also more environmentally friendly, as they do not contain toxic heavy metals like lead or cadmium. Overall, the use of a lightweight, compact lithium-ion battery in the KX250's electric start system contributes to the bike's performance, handling, and reliability.

The bike also features a hydraulic clutch, a new slim aluminium frame, and an updated engine
The KX™250 motorcycle is a high-performance dirt bike and one of Kawasaki's flagship technologies. The bike features a new slim aluminium frame, an updated engine, and a hydraulic clutch, among other features.
The new slim aluminium frame is a lightweight perimeter frame that delivers lighter, nimbler handling and stability. It has a revised rigidity balance, offering an improved front-end feel for better cornering performance across a wide range of conditions. The bike's suspension duties are handled by a high-performance Showa 49mm, inverted coil-spring fork. The large-diameter inner tubes and large 25mm damping pistons deliver smooth action and firm damping.
The KX™250's engine has been updated to include an aligned intake and a new, centrally positioned, straight exhaust port. These updates deliver higher airflow efficiency, strong overrun, and smooth, low-rpm torque for improved power. This is especially useful when riding at low-end speeds, up hills, or under loads. The intake camshaft is 10mm higher, and the exhaust valve angle is 1-degree narrower, both providing better performance at low rpm.
The bike also features Kawasaki TRaction Control (KTRC), which can be activated at the push of a button. This allows riders to quickly select from two levels of control (weak and strong) to suit conditions and preferences. The KX™250 also has two engine maps (Normal and Aggressive) that can be easily switched between using the Mode (M) button on the left handlebar.
The hydraulic clutch is a great feature for tight technical terrain or heavier-than-stock clutch springs. It requires up to 20% less force to pull the lever, thanks to its built-in fluid reservoir and slave cylinder. This makes the lever pull consistent and predictable throughout its range.

The 2021 Kawasaki KX250 is priced at $8,299, the same as the 2021 Yamaha YZ250F. This price point is impressive when compared to other brands. For instance, the 2021 Husqvarna FC250 is priced at $9,399, while the Honda CRF250 is $7,999. The Yamaha YZ250F is expected to be released soon, and the Honda CRF250 is expected to be updated in 2022.
The 2021 KX250 has received the biggest changes of all the 250 four-stroke motocross models, with improvements in handling, comfort, suspension, and power. Notably, Kawasaki has added an electric start, a hydraulic clutch, an updated engine, a new frame, a new swingarm, and new bodywork. The kickstarter has been removed, leaving the Suzuki as the only kick-starting four-stroke model.
The new model has Dunlop MX3S tires and a new crank design to reduce weight and optimize performance. The engine now revs up to 14,500 rpms, 250 rpms higher than the previous year's model. The piston head is flatter to increase compression, and the intake is smoother and longer. The clutch has been updated with a "coned disc spring", also known as the Belleville washer spring, which has been used in KTM and Husqvarna clutches.
The 2021 KX250's electric start is a convenient feature that riders appreciate, even if it doesn't directly improve lap times. The hydraulic clutch is also a notable improvement, making Kawasaki the third manufacturer to sell a 250 four-stroke with this feature, after KTM and Husqvarna.
