Rider Profile

Best For	Suits a rider comfortable with a heavy, low-powered cruiser that demands relaxed, deliberate inputs rather than quick reflexes.
Purpose	Built for laid-back boulevard cruising and classic custom styling rather than outright performance or long-haul touring comfort.
Rider Fit	A hefty machine at nearly 300kg, so riders need decent strength and confidence for slow-speed maneuvers and parking.
Character	A classic Softail Custom with deep V-twin thump, chopper-style stance, and laid-back attitude over raw speed.
Not Ideal For	Not for riders seeking sharp cornering agility, off-road capability, or brisk acceleration from this notably de-tuned engine variant.
