Rear Cylinder Deactivation

Designed as an aid to reduce engine and exhaust heat to the rider, Rear Cylinder Deactivation turns off the rear cylinder when the engine gets hot.

The following condition must be met for Rear Cylinder Deactivation to be enabled.

  • Engine must be up to operating temperature

  • Ambient Temperature must exceed 59 f (15 c)

  • Engine speed must remain below 1000 rpm

  • Throttle must be in the closed position (0% throttle)

  • Exhaust catalyst temperature must be sufficiently high for tailpipe emissions compliance.

NOTICE
If catalyst temperature drops below emissions threshold the rear cylinder will re-engage until the catalyst temperature rises above the threshold at which point the rear will deactivate again.

Cylinder Deactivation can be turned off by accessing the settings menu in the drop-down from the top of the screen. Cylinder Deactivation controls are in the Vehicle menu. When Rear Cylinder Deactivation is functioning, an icon will illuminate at the top of the Ride Command display screen.
