Description
If your 650cc V-Twin feels inconsistent or jumpy at low throttle openings, the Throttle Position Sensor is usually the first suspect. This high-quality aftermarket unit provides an accurate, reliable signal to your ECU, restoring smooth power delivery. This specific model is a bolt-on installation for the early 2-bolt throttle body configuration used up to approximately 2014. We verify fitment on our own donor bikes, so you can be confident in a reliable swap.
