Have you ever heard of a 5-speed transmission dipstick breaking off and working its way into the transmission with disastrous results? Ask any seasoned technician; he’s seen one. Over time, the low frequency firing pulses of the American V-twin make the stock zinc die-cast dipstick break off and now you know the rest of the story. Bigger motors make this situation even worse. BAKER redesigned the dipstick with the largest radius possible between the stalk and the head. This radius stiffens the dipstick and increases its natural frequency.
