Altis Omega 2027 | Full-Size Electric Dirt Bike for Motocross & Racing

2027 Altis Omega | Full-Size Electric Dirt Bike Full-Size Geometry. Serious Electric Power. The Altis Omega, formerly known as the Sigma Mega, brings full-size motocross dimensions to riders ready to move beyond a compact e-moto. Designed and engineered in California, the Omega pairs a high-output electric powertrain with 21-inch front and 18-inch rear wheels, adjustable ergonomics, and suspension options built for demanding off-road riding. The Standard version starts with a 144V powertrain, 5040Wh Altis semi-solid-state battery, and automotive-standard hairpin motor producing 55kW peak power, or 74HP. That combination delivers immediate electric response with the wheel sizing and cockpit space riders expect from a full-size dirt bike. The Pro adds KYB suspension and upgraded braking and drivetrain components, while the Alpha introduces a separate 360V system rated at 75kW, or 100HP. For motocross, desert riding, and enduro terrain, setup matters as much as power. The Omega gives riders adjustable controls, onboard tuning, and common motocross component interfaces to help tailor the bike to the terrain and their riding style. Electric drive also eliminates routine combustion-engine tasks such as engine oil changes, while the chain, brakes, tires, and suspension still need regular attention.

Common component sizing gives riders more options when choosing bars, tires, and other setup parts. The display and tuning interface are shared with the 2026 Altis Sigma platform. Riders can access power mapping, throttle sensitivity, regenerative braking, and custom ride mode settings through the onboard display. These adjustments let you change how the bike responds, which is useful when moving between tighter trails and more open terrain. Ride Modes: Eco, Normal, Sport, and Race Power Mapping: Adjustable through the display Throttle Sensitivity: Onboard tuning Regenerative Braking: Adjustable settings Custom Ride Modes: Configurable through the display Handlebar Mount: Standard 1 1/8-inch clamp Foot Peg Interface: Existing Altis peg platform Color Options: Black and Red Wheel Fitment and Component Compatibility KTM Wheel Fitment: Listed compatibility with 2004 through 2024 KTM 125cc to 500cc models, including the KTM 450 SX-F Stark Wheel Fitment: Listed compatibility with Stark VARG wheels Handlebar Fitment: Standard 1 1/8-inch handlebar clamp setup Foot Peg Fitment: Existing Altis peg platform Check the specific wheel assembly and required mounting hardware before ordering replacement wheels or planning a swap. What Makes the Omega Stand Out? The Omega puts its strongest features where riders can use them: a 55kW automotive-standard hairpin motor on the Standard version, a 5040Wh semi-solid-state battery, and full-size 21/18-inch wheels. The larger front wheel helps carry the bike through uneven terrain, while the 18-inch rear provides familiar off-road tire sizing. Adjustable regenerative braking adds another way to tune deceleration to your preference. For riders pushing harder, the Pro's KYB fork and KYB rear suspension make it the version to consider for its upgraded suspension package. The Alpha takes a different step with a higher-voltage power system and increased output, although its full specifications remain pending. Off-Road Use The Altis Omega is intended for private property, off-road, and track use only. It is not intended for public roadways. Please ride responsibly. Who Is the Altis Omega For? Experienced motocross riders: Riders looking for full-size electric performance with onboard tuning and a Pro option featuring KYB suspension. Desert and enduro riders: Riders who value full-size wheels, 12.6 inches of ground clearance, and adjustable power delivery for varied terrain. Riders stepping up from smaller e-motos: Experienced 60V and 72V riders ready for a larger chassis, taller cockpit, and substantially higher output.
