Harley Davidson motorcycles are known for their power and road presence. Many use a system called Throttle by Wire (TBW). This article will look at common TBW problems and their solutions.
What is Throttle by Wire?
Throttle by Wire removes the usual cables between the throttle and engine. Instead, it uses electronic signals to control the throttle. This system is now common in many Harley Davidson bikes.

Owners have reported problems with TBW. Below are the most common issues.
- Grip Lag: A delay when you twist the throttle.
- Sticky Throttle: The throttle does not move smoothly.
- Failure to Respond: The motor does not respond to the throttle.
- Throttle Error Codes: The bike’s system shows warning codes.
