 This example (which should apply more widely) is based on a 2012 883 Superlow that was converted to a 1250 with a different Primary Engine Sprocket and different final drive belt sprocket. These changes altered the calculation required to accurately display the proper gear. The recalculation was entered into a Powervision engine tuning unit. This example (which should apply more widely) is based on a 2012 883 Superlow that was converted to a 1250 with a different Primary Engine Sprocket and different final drive belt sprocket.
