STREET FIGHTER

Update 3/10/14

CLASS REQUIREMENTS                                                                     

DESIGNATION: SF, followed by rider number.

Street Fighter is the street bike index class contested at AMA Dragbike 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 without the aid of wheelie bars. All compete with a heads-up, pro tree start. Street Fighter is run on qualified 64 bike field, based on a standard of 9.50/6.10 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 Handicap “break-out” procedures. All entries must be self-starting. No starter carts or bump starts permitted.

This class will be a points class at all MANUFACTURERS CUP events.

It will be the riders responsibility to monitor his or hers points earnings after every event. All requests for points adjustments must be made in writing to info@mancup.info within thirty days of the points posting for the event in question on all events EXCEPT the Finals. For the Finals ONLY, all requests for points adjustments, again, must be made in writing to info@mancup.info and within TEN days of the points being posted. Please understand the Man Cup will strive to keep the points tabulations for all classes accurately and correctly and we do hope by you monitoring your own points earnings that any errors or miscalculations can be corrected in a timely fashion.

CATCH CANS

Any engine with any power-adder must have a crankcase vent catch can.

 

CLUTCH

Clutch must be hand activated, and have enough static clutch pressure to stall the engine when the clutch is released at 1200 rpm with the front brake applied (same as PST). If this is the case, they are legal.

 

TRANSMISSION

Air or electric shifters permitted.

 

BRAKES

Front and rear hydraulic brakes are required.

 

FRONT SUSPENSION

Rigid forks prohibited. All entrants must maintain a minimum of 1” travel.

Wheelie bars are prohibited

 

GROUND CLEARANCE

TIRES

WHEELS

Minimum front wheel diameter is 16”. Maximum rear wheel width is 7”.

 

ELECTRICAL KILL SWITCHES

Tethered kill switches required. Kill switch must shut off all fuel pumps and nitrous equipment. Normally aspirated bikes with stock electrical systems and functional factory tip-over switches may waive the required tether kill switch. Any bike with any power-adder MUST have a legal tether kill switch.

 

ELECTRONIC DEVICES

2-steps are prohibited. Cross-over or delay boxes are prohibited. Any device designed to limit front wheel lift is prohibited.

MSD SB6, Schnitz Ignitions, stand alone ECU, ECU editors, etc are permitted in Crazy 8, Street Fighter and Street ET classes. The 2 step feature cannot be used. Though, and if certain wires can be unhooked they need to be. In other words, there clutch switch should not be wired to a 2 step input on the box if there is a designated input for that. If someone had a MSD 2-step, or MSD 4350 which sole’s purpose is for a 2 step, then it must be removed. Any other box that has other functions is permitted. There really is no way to outlaw everything, as technology keeps progressing, but it will be monitored

Pants and jacket are not required to be zipped together. Nylon or textile jackets and pants are not permitted, even if they have pads. All jackets and pants must be made of 100% leather.
