  • Cruise control comes standard.

• Gauges: Riser-mounted speedometer that shows RPM, gear, fuel — clean and functional.

Ride Experience & Practical Use

• Power Delivery: The 103B engine offers a strong torque curve, especially in low to mid RPM, which feels powerful and punchy during acceleration.

• Cruising: Excellent for straight-line cruising due to its long wheelbase and stable frame.

• Comfort: The low seat height + aggressive stance gives a cruiser feel, but long rides may be less comfortable than more relaxed touring bikes.

• Maneuverability: With that long, stretched profile, tight turns or slow-speed maneuvering require more skill / awareness.

• Security: Smart Security system is a big plus (proximity key), making it more than just a raw muscle cruiser.

• Fuel Range: With a 5 gal tank, it's decent for cruising but not built for ultra-long touring without gas stops.
