This performance bobber combines old‑school soul and modern form featuring a torquey V‑Twin engine.
Modern Air-Cooled V-Twin
The 58 cubic inch (942cc) engine is an air-cooled SOHC 60° 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
To keep friction loss to a minimum, increase durability and help the engine achieve the ideal performance characteristics, special roller-type rocker arms with needle bearings are used.
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.
Sophisticated twin-bore fuel injection is used on the Bolt R-Spec to deliver ultimate urban riding fun with strong acceleration. 3D maps for ignition timing and fuel injection have been developed to deliver outstanding acceleration 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 styling of the machine. The minimalist-style exhaust system delivers a throaty and pleasing exhaust note.
A double-cradle frame enhances city riding enjoyment thanks to an engine mounted to the frame with a rigid mount system that provides precise handling.
Low Seat Height
The low-set seat is a mere 27.2 inches off the pavement, so most riders can easily put both feet firmly on the ground at a stop, as well as enjoy the great riding position the seat provides.
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 handling on the open road.
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 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
12-spoke cast alloy wheels are used to provide strength and toughness. Bridgestone® tubeless 100/90-19 size front and 150/80-16 size rear tires help provide excellent road grip.
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 to enhance Bolt RSpec styling. For 2017, the tank features a new flangeless design for even cleaner lines.
LED rear taillight looks cool and adds to the modern bobber appeal.
Compact digital LCD meter assembly provides clean styling with excellent visibility.
Real Steel Fenders
Steel front and rear fenders are ideal for personalization, including paint and customization.
Solo rider saddle adds to the minimalist bobber look while providing good support for longer rides.
