27kW. 80 MPH. Mid-size platform. No compromises.
 
The SRPNT Z27 takes everything riders love about the modern mid-size e-moto category and turns it up another level. Built around a powerful 27kW (36.2 HP) mid-drive motor, a massive 72V 60Ah Samsung-cell battery, and a forged aluminum chassis, the Z27 is designed for riders who want true dirt bike performance without jumping to the size and weight of a full-size motocross bike.

Performance That Earns Respect
The SRPNT Z27's 27-kilowatts at the motor isn't a marketing number. It translates to 39.8 ft-lbs of shaft torque at 1,000 RPM, 65-degree climbing capability, and an 80 mph top speed on a 210 lb platform. The PMSM controller runs four modes -- High, Drive, Eco, and Reverse -- so you can dial the power delivery to the terrain, not the other way around.
Acceleration is immediate. Throttle response is linear through the full powerband. On technical singletrack or wide-open desert sections, the Z27 doesn't ask you to manage it -- it goes where you point it.
How The Z27 Fits in the Mid-Size Category
The Throne SRPNT Z27 competes directly with the Ultra Bee, Talaria Komodo, and 2026 Altis Sigma. Riders coming from gas will find ergonomics similar to a modern 125cc two-stroke -- substantially larger than lightweight e-motos, noticeably smaller and lighter than a 250cc motocross machine. The 880mm seat height and 1,380mm wheelbase put it in familiar territory for experienced trail riders.
At 27kW, it's producing more power than most bikes in this size class. If you've outgrown an Ultra Bee, the Z27 is the next logical step.
Z27 Chassis
Built around a forged 6061 T4/T6 aluminum frame and swingarm, manufactured using a massive 3,000-ton forging process, the chassis provides excellent rigidity and durability while maintaining manageable weight. Combined with a 1,380mm wheelbase, 300mm ground clearance, and full-size 19/18 wheel package, the Z27 feels planted at speed while remaining agile enough for tight trails.
The Z27's Brakes Built for the Power
One of the standout features of the SRPNT Z27 is its use of real motorcycle-spec braking components, not the smaller e-moto brake systems commonly found on lightweight platforms. With over 36 horsepower available and a top speed reaching 80 mph, larger brakes provide improved stopping power, better heat dissipation, and greater rider confidence when pushing the bike hard.
Tires
The Z27 comes equipped with dual-sport tires inspired by the proven Shinko 241 tread pattern. This versatile tire design offers excellent traction on dirt, gravel, hardpack, and pavement while maintaining predictable handling and durability. Riders who split time between trail systems, fire roads, and connecting pavement sections will appreciate the balance these tires provide.
How the Z27 Fits in the Mid-Size Category
In terms of size, the SRPNT Z27 falls into the same size category as the Ultra Bee, Talaria Komodo, and the Altis Sigma. Riders coming from gas-powered motorcycles can think of the Z27 as having ergonomics similar to a modern 125cc two-stroke or four-stroke race bike. It is substantially larger than lightweight e-motos while remaining noticeably smaller and easier to manage than a full-size 250cc motocross machine.
The combination of 27kW of power, Samsung battery technology, KKE suspension, forged aluminum construction, moto-spec brakes, and proven 19/18 wheel sizing makes the SRPNT Z27 one of the most powerful and capable mid-size electric dirt bikes available.
