Rider Profile

Best For	This is a demanding machine best suited to experienced riders who are comfortable with a light, twitchy, high-compression single-cylinder supermoto.
Purpose	Built for supermoto competition and aggressive cornering, blending motocross-derived lightness with street-focused tires and brakes for tarmac attack.
Rider Fit	Expect a tall, aggressive, minimal seat and a physically demanding ride requiring active body positioning, strong legs, and core engagement.
Character	Raw, punchy, and razor-sharp handling define this bike, with a big-bore two-stroke-like snap of power delivery and premium Ohlins/Paioli suspension for serious cornering feedback.
Not Ideal For	This is not a good fit for beginners, commuters wanting comfort, or anyone seeking a relaxed, long-distance touring machine.
