Chassis / Suspension

• HANDLING-FOCUSED FRAME: A double-cradle frame provides precise handling and enhances city riding enjoyment thanks to the rigid mount system mounting the engine directly to the frame.
• LOW SEAT HEIGHT: The low-set seat provides a great riding position while being a mere 27.2 inches off the pavement, so most riders can easily put both feet firmly on the ground at a stop.
• AGILE WHEELBASE: Bolt R-Spec’s short, 61.8-inch wheelbase contributes to the bike’s great handling, providing precise, tight turns in city riding and solid, stable handling on the open road.
• ADVANCED SUSPENSION: The beefy front 41mm fork tubes offer excellent suspension performance and the twin rear shocks, which include piggyback style gas chambers, have been tuned to provide great comfort and handling while contributing to the machine’s low, aggressive profile.
• LOW MAINTENANCE BELT DRIVE: At just 21mm wide, the drive belt contributes to the slim and clean look of the rear end. The belt has a carbon-fiber core which adds strength and durability for longevity.
• MODERN WHEELS AND TIRES: Distinctive 12-spoke cast alloy wheels provide strength and toughness while Bridgestone® tubeless 100/90-19 size front and 150/80-16 size rear tires offer excellent road grip in varying conditions.
• POWERFUL BRAKING: The 298mm front disc brake and 298mm rear disc brake both use wave rotors, the style usually found on sport bikes. The front brake uses a floating mount for great heat-distortion resistance, contributing to excellent braking performance.
• SLIM, STYLISH FUEL TANK: The 3.4 gallon fuel tank is a traditional teardrop style with a slim shape that includes flattened top and side surfaces. Plus the premium flangeless design makes for even cleaner lines, enhancing the Bolt R-Spec's custom styling without the ugly tank seams found on so many other bikes in the class.

Engine

• AIR-COOLED V-TWIN: The 58-cubic-inch (942cc) engine is an air-cooled SOHC 60-degree V-twin with four valves per cylinder, a pent-roof shaped combustion chamber and 9.0:1 compression ratio. The engine is designed to provide excellent power and superior low-end torque.
• LOW FRICTION INTERNALS: Special roller-type rocker arms with needle bearings are used to keep friction loss to a minimum, increase durability and help the engine achieve the ideal performance characteristics.
• ADVANCED CYLINDER DESIGN: The pent-roof combustion chamber shape was precisely engineered to direct the fuel/air charge to the center of the piston for more efficient combustion and maximum power. Ceramic-composite plated cylinders provide excellent heat dissipation and reduced oil consumption.
• LIGHTWEIGHT PERFORMANCE PISTONS: High-quality forged aluminum pistons have a lightweight, high-strength, compact design that contributes to reduced vibration and increased durability.
• FUEL INJECTION: A sophisticated twin-bore fuel injection is used on the Bolt R-Spec to deliver strong acceleration for the ultimate in urban riding fun. Precise 3D maps for ignition timing and fuel injection enhance performance in the mid- and low-speed ranges.
• COMPACT AIR CLEANER: The stainless steel air cleaner cover provides a “raw metal” look that accentuates the Bolt R-Spec’s distinctive styling. In addition, the air cleaner design provides great intake efficiency and enhanced torque characteristics.
• UNIQUE BOLT EXHAUST SYSTEM: A 2-into-1 exhaust pipe layout on the right side of the engine contributes to the lively performance and minimalist styling of the machine, while delivering a rich, throaty exhaust note.
