CTX1300 Engine

Engine overview

The CTX1300 is equipped with a liquid-cooled V4 1261.4-cc engine-the same engine type adopted on the STX1300.

For equipping the CTX1300 with this engine, the development team has successfully improved torque in the low- to mid-speed ranges in order to achieve engine characteristics for even better ease of handling on city streets.

To bring satisfaction to customers seeking higher quality, original engine settings worthy of the CTX1300 are offered to produce that distinctive V4 throbbing feel.

Engine overview

The exhaust system is composed of twin exhaust pipes, one pair each coming out side-by-side from the engine's right and left cylinders with an extended mid-section in the front pipe. This design optimizes the exhaust sound from each cylinder, creating that distinctive V4 exhaust with its enchanting, throbbing feel.

The exhaust is efficiently purified, and the CTX1300's environmental performance meets the Euro 3 emission standards.

A shaft drive system is used to ensure smooth starting and acceleration. From getting around on city streets to long-distance cruising, riding with ample torque and power is always ensured.

The low engine speed settings, including the torque in the low- to mid-speed ranges and the optimized final drive ratio, ensure more pleasant cruising.

Engine details

The following characteristics highlight the engine's strong presence.

  • A liquid-cooled, longitudinal V4 1261.4-cc DOHC engine inheriting the best of the STX1300 engine, including a 90 degree included angle for the cylinder and bore-stroke settings of 78.9 by 66.0 mm.
  • A biaxial secondary balancer that minimizes unpleasant vibrations, achieving comfortable riding with little fatigue even when traveling a long distance.
  • Valve timing improvements together with air intake and exhaust settings optimized for the low- and mid-speed ranges achieve better combustion efficiency.
  • An altered compression ratio that allows the use of regular gasoline.
  • The exhaust system is composed of twin exhaust pipes, one pair each coming out side-by-side from the engine's right and left cylinders with an extended mid-section in the front pipe.

TCS (For the DX Type)

The TCS provides assistance functions to the CTX1300 rider to enable riding with a greater sense of security. The system suppresses any rear wheel spin that could occur when starting or during a ride, thus mitigating concerns about potential wheel spin when operating the throttle.

The system offers a reassuring ride when starting, accelerating or riding particularly on wet slippery roads or on unpaved roads.

The TCS transmits signaling information from the wheel speed sensor to the ECU via the ABS modulator. The ECU then calculates the slip ratio and determines the injection thinning patterns of the PGM-FI in order to control the drive wheel rotation. This activates the following mechanism:
Engine torque is controlled to restrain any excessive slip or changes in vehicle behavior.
The indicator flashes to inform the rider of any excessive driving force.
The TCS switch is located on the top of the left handlebar and can be turned off as conditions warrant.
