Common questions
What are the primary benefits of a 25-tooth sprocket on a Touring bike?
A 25-tooth sprocket will significantly lower your engine RPMs at highway speeds compared to stock or smaller sprockets. This can result in a more relaxed ride, reduced engine wear, and potentially better fuel economy, especially on long trips.
Will this sprocket require a dyno tune?
Changing your countershaft sprocket typically does not require a dyno tune, as it only alters the final drive ratio and not the engine's fuel or ignition mapping. However, always ensure your chain tension and alignment are correct after installation.
Is this sprocket compatible with all Harley Touring and Softail models?
This PBI sprocket is designed for V-twin Harley-Davidson models that utilize a 530 pitch chain. Due to variations across models and years, we recommend checking your bike's specific fitment using our Shop by Bike tool before purchasing.
