Honda Unicam power
The Cota 4RT260 uses an exclusive Honda 259 cc liquid-cooled 4-valve Unicam engine that was designed and tuned specifically for the unique demands of trials riding, including the need for ultra-strong low-rpm power.
A high-pressure fuel pump helps to boost midrange and top-end performance while maintaining the engine’s excellent power delivery at low rpm.
Easy to modulate
Programmed Fuel Injection (PGM-FI) with a narrow, high-velocity 28 mm throttle body ensures rapid fuel/air flow and precise cylinder filling, resulting in crisp power delivery that’s easy to modulate – so critical in trials riding.
Battery-less digital ignition includes a bank-angle sensor to switch off the ignition when the motorcycle is lying horizontal.
Linear power curve
Precise mapping of the ignition system’s ECU gives the engine a consistent power curve, particularly in the low and mid ranges.
Reduced engine braking
A crankcase decompression system limits engine braking when closing the throttle for improved rider control, making the bike feel lighter and easier to handle.
Optimum fan placement
The radiator fan is positioned in a manner that promotes evacuation of dirt, pebbles or other objects and prevents blockage of the fan itself.
Smooth, accurate shifting
Gearing in the close-ratio five-speed transmission was selected to perfectly match the engine’s powerband so you always have the perfect gear for whatever section you’re riding.
Dual Map ECU
Traction different from one section to the next? No problem. The Cota’s ECU lets you choose between two ignition maps with the flick of a handlebar-mounted switch.
