Marketing departments love unloaded dyno runs where the rear wheel spins freely on a work stand. In the wild, wind resistance, rolling rolling resistance, and rider mass tell the real story.

Telemetry runs recorded across dry lakebeds and paved private stretches show a distinct acceleration pattern:

• Completed in 1.9 seconds. The initial throttle bite requires active rear-brake feathering or lean-forward body English to keep the front wheel down.
• Achieved in 4.1 seconds. Power delivery remains linear throughout the mid-range without noticeable voltage sag.
• The bike tops out between 72.4 and 74.1 mph, holding that velocity for sustained pulls across a quarter-mile before safety cutouts protect cell temperatures.

Off-road conditions paint a different picture. On hardpacked dirt or loose fire roads, rear wheel slippage limits usable top speed to 58, 63 mph. Pushing past 60 mph on dirt requires precise throttle feathering, as the aggressive torque curve can easily overwhelm knobby tires on loose gravel.
