Sport Touring
is set up at 10.5:1 and is preferred for Baggers and heavy Softails that have access to 91+ octane fuel and are mostly driven by a solo rider. These are very reliable combinations but may require a modification in riding style ‘if’ lower, less than 91 octane, fuel is purchased. Usually this means down shifting to pass (eliminating detonation) instead of just rolling it on

Power and fuel mileage expectations.    Torque       Horsepower         Mileage
Sport Touring                                           115-125         110-120            45 MPG
The above using stock carbs or throttle bodies and good 2 into 1 pipes. Larger carbs and throttle bodies will increase HP and decrease Torque.
