Rider Profile

Best ForThis trike suits riders who are comfortable with a wide, car-like three-wheeled footprint rather than traditional two-wheel balance and countersteering skills.
PurposeIt is built for relaxed, stable cruising and showy boulevard presence rather than speed, agility, or performance riding.
Rider FitThe heavy 394 kg dry weight and wide 255-section rear tire mean it takes little balance skill but demands comfort maneuvering a bulky, car-width vehicle at low speeds and parking.
CharacterIt has a laid-back, low-revving V-twin character with shaft drive smoothness, favoring torque-driven cruising over revvy excitement.
Not Ideal ForThis is not the machine for riders seeking quick acceleration, tight cornering agility, or any off-road capability.
