2027 KX327 Launch
Kawasaki introduced the 2027 KX327 motocross and KX327X cross-country two-stroke motorcycles, alongside revised KX250F and KX450F four-stroke models. The two-strokes are the first displacement-over-250 cc two-strokes from Kawasaki since the KX500 ended production in 2004.
Background
Kawasaki halted large-bore two-stroke production in 2004, ending the KX500 line. After teasing a new two-stroke at the 2025 Anaheim show, the company issued a press release titled “TWO-STROKE REVOLUTION 2027,” confirming the return of a high-displacement two-stroke platform.
Key Players
The launch is led by Kawasaki’s engineering team and the Kawasaki Racing Team. Development of the 2027 KX450F incorporated rider input from MXGP World Champion Romain Febvre. The RIDEOLOGY THE APP KX2 supplies the software for rider-adjustable maps and controls.
Specs
KX327: 327 cc fuel-injected two-stroke, five-speed, ~6 lb lighter than KX450F, MSRP $9,099; KX327X adds six-speed and 2.2-gal tank, MSRP $9,699. KX250F: +0.7 hp, +0.5 kW, +0.3 Nm, –0.15 lb, clutch spring 15 % higher. KX450F: new chassis, Brembo brakes, Power Mode/KTRC/Launch Control. All four-strokes use RIDEOLOGY THE APP KX2 for map selection and data logging.
Impact
Kawasaki adds a two-stroke option after a 22-year gap. Fuel injection and selectable ECU maps aim to reduce issues like power delivery and emissions. With a displacement below the market’s largest two-stroke (Beta 350RX), the KX327 occupies a niche position.
Official Comments
Kawasaki’s press release says the two-stroke platform delivers “smooth, predictable power delivery from ultra-low to mid rpm” via fuel injection, notes the models share KX450F chassis, and cites MXGP champion Romain Febvre for upgrades. It also highlights RIDEOLOGY THE APP KX2 for map selection, traction control and maintenance alerts.
Opposition
Observers note two-stroke engines are louder and emit more pollutants than four-strokes, a concern. Analysts point out the KX327’s displacement is smaller than the market’s largest two-stroke, the Beta 350RX, limiting its size claim. Some riders may find the selectable “Aggressive” map and output demanding for less-experienced users.
Gaps
Kawasaki has not disclosed peak horsepower or torque for the KX327 models, leaving performance comparisons incomplete. Availability dates differ: the two-stroke line is slated for delivery in late 2026, the KX250F is expected in mid-September 2026, and the KX450F in mid-December 2026. Final specifications may be confirmed nearer launch.
