We are offering our 103 inch kits for 2007 and later models in three configurations to suit all possible applications.
We call them Touring, Sport Touring and Sport
Touring packages will have a compression ratio of 10:1 and should be used on Baggers and heavy Softail models used for two up riding in regions that have steep grades and/or lower octane fuels. (under 91 octane)
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.
