Introducing the 2005 Derbi Mulhacen 659, a striking naked bike that embodies the spirit of urban exploration and spirited riding. Crafted by the renowned Spanish manufacturer Derbi, this motorcycle is designed to cater to enthusiasts who seek a blend of stylish aesthetics and robust performance. With its modern lines and minimalist design, the Mulhacen 659 stands out in the crowded motorcycle market, appealing to riders who appreciate both form and function. It captures the essence of freedom on two wheels, making it an ideal companion for city commutes and weekend escapades alike. At the heart of the Mulhacen 659 is a potent 659cc single-cylinder, four-stroke engine that delivers an exhilarating 48.60 horsepower at 6,000 RPM. This power tapers seamlessly into a five-speed gearbox, ensuring a responsive and engaging ride. The engine’s 10.0:1 compression ratio harmonizes performance with efficiency, making it suitable for both spirited accelerations and relaxed cruising. With a weight of just 160 kg (352.7 lbs), the Mulhacen boasts a remarkable power-to-weight ratio of 0.3038 HP/kg, providing riders with a nimble feel and enhanced control. The liquid cooling system ensures that the engine remains at optimal temperatures, even during those longer rides, allowing you to push the limits without overheating. The Mulhacen 659 is equipped with advanced features that enhance both safety and comfort. The front suspension utilizes an upside-down fork with a travel of 120 mm, ensuring superior handling and stability over various terrains. Coupled with a progressive lateral link rear suspension offering 110 mm of travel, riders experience a plush ride, whether navigating city streets or tackling winding roads. The braking system features a single disc setup both front and rear, with a robust 320 mm front disc for confident stopping power. With an electric starter for effortless ignition and a seat height of 800 mm, the Mulhacen caters to a wide range of riders, making it accessible without sacrificing performance. **

Pros

  • Engaging Performance: The 659cc engine provides a thrilling ride with responsive acceleration and a lightweight chassis for enhanced maneuverability.
  • Stylish Design: The minimalist aesthetic and modern lines make the Mulhacen a head-turner, perfect for riders who want to make a statement.
  • Comfortable Ride: With advanced suspension systems and an adjustable seat height, it offers a comfortable experience for both short trips and long rides.

Cons

  • Limited Fuel Capacity: With a fuel tank holding only 9 liters (2.38 gallons), longer journeys may require more frequent stops for refueling.
  • Single-Cylinder Vibration: The single-cylinder engine can produce noticeable vibrations at higher RPMs, which may deter some riders seeking a smoother ride.
  • Naked Bike Exposure: While the naked design enhances style and agility, it also means less wind protection, which can be a drawback on longer highway rides.
