Update 1/6/212

CLASS REQUIREMENTS                                                                     

DESIGNATION: SF, followed by rider number.

Street Fighter is an index class contested at ManCup National events and is considered the entry point into index racing. Most bikes compete with either big displacement normal aspirated motors to nitrous or turbocharged machines with a D.O.T street tire or drag slick and with or without the aid of wheelie bars. All compete with a heads-up, pro tree start. Street Fighter is run on an all run qualified field, based on a standard of 9.50 1/4 mile and 6.10 1/8th mile index. Standard safety is a requirement. During qualifying, runs quicker than the 9.50/6.10 index will be placed at the bottom of the qualifying sheet. During eliminations, runs quicker than the standard disqualify the rider under “break-out” procedures. All entries may be either self-starting or via use of a starter cart.
