Control system, straddle type vehicle, control method, and storage medium

A control system of a straddle type vehicle including a front suspension mechanism and a rear suspension mechanism, comprising:

• a detector configured to detect a stroke speed of the front suspension mechanism;
• a controller configured to control a damping force of the rear suspension mechanism;
• and
• at least one processor with a memory comprising instructions, that when executed by the at least one processor, cause the at least one processor to:
• determine an operation state of the vehicle;
• and
• transition a control mode of the rear suspension mechanism controlled by the controller from a first mode to a second mode, when determining that the operation state of the vehicle is a first state in which a rear wheel of the vehicle is slipping or a second state in which the vehicle is doing a wheelie,
• wherein the first mode is a mode of changing the damping force of the rear suspension mechanism according to a detection result of the detector, and the second mode is a mode of fixing the damping force of the rear suspension mechanism,
• wherein the at least one processor is configured to change a transition time spent for transition of the control mode from the first mode to the second mode, depending on the operation state.
