While the Honda CMX 1100 Rebel is often categorized as a standard cruiser, its engineering DNA is far more exotic. It utilizes a re-engineered version of the 1,084cc parallel-twin engine found in the CRF1100L Africa Twin. To achieve its signature cruiser character, Honda engineers increased the flywheel mass by 32%, significantly enhancing low-end inertia and providing a distinct, rhythmic ‘pulse’ that sets it apart from its adventure-touring cousin.
Technical Review: Performance and Architecture
The SC87A platform represents a paradigm shift in the heavyweight cruiser segment. By utilizing a 270-degree phased crankshaft, Honda has successfully emulated the power delivery of a V-twin while maintaining the compact packaging and cooling efficiency of a parallel-twin. The frame is a tubular steel trellis design, optimized for a low center of gravity (seat height of just 700mm), ensuring high-speed stability and nimble low-speed maneuvering.
The inclusion of advanced electronics—including Honda Selectable Torque Control (HSTC) and Wheelie Control—is managed via a sophisticated Ride-by-Wire system. This allows the CMX 1100 to bridge the gap between classic aesthetics and contemporary safety standards, providing a level of rider customization rarely seen in the bobber category.
Maintenance Guide: Professional Service Standards
Lubrication System
For the SC87A, Honda mandates SAE 10W-30 oil conforming to the JASO T 903 MA standard. During a standard oil and filter change, the system requires 3.4 liters. It is critical to use MA-certified oil to ensure the wet clutch (especially on DCT models) operates without slippage or premature wear.
Chassis and Contact Patch
Tire integrity is paramount for the Rebel’s handling characteristics. The front 18-inch wheel requires 2.25 bar (33 psi), while the high-load rear 16-inch wheel must be maintained at 2.80 bar (41 psi). Regular inspection of the 180/65B16 rear tire is advised, as the high torque output of the 1100cc engine can accelerate center-tread wear if pressures are not meticulously managed.
Ignition and Electrical
The SC87A utilizes high-efficiency NGK LMAR8G spark plugs. Given the engine’s high-compression nature, maintaining clean electrodes is vital for fuel economy and smooth idling. The electrical system is anchored by the YTZ14S battery; given the electronic density of this model, keeping the battery on a tender during long storage periods is highly recommended to prevent ECU voltage drops.
Editor’s Verdict
The Honda CMX 1100 Rebel (SC87A) is a masterclass in modular engineering. By taking a world-class adventure engine and retuning its rotational mass, Honda created a cruiser that is both reliable and characterful. From a technical perspective, it is one of the most accessible ‘big bikes’ to maintain, provided the technician adheres to the specific JASO oil requirements and tire pressure specifications outlined above.
