INTERNATIONAL KART FEDERATION 2021 COMPETITION REGULATIONS AND TECHNICAL MANUAL READ THIS DISCLAIMER BEFORE PROCEEDING The rules and/or regulations set forth herein are designed to provide for the orderly conduct of racing events and to establish minimum acceptable requirements for such events. These rules shall govern the condition of all events and by participating in these events, all participants are deemed to have complied with these rules. No express or implied warranty of safety shall result from publications of or compliance with these rules and/or regulations. They are intended as a guide for the conduct of the sport and are in no way a guarantee against property damage, injury or death to a participant, spectator or official. The sport of karting has inherent risks. One who participates in the sport of karting does so with the assumption of those risks, including mechanical failures which may result in injury or damage. Use of this Rule Book is with the express understanding that the responsibility for the condition and operation of a kart or any other kind of vehicle in competition is that of the owner and/or driver of the kart or other vehicle. While IKF seeks to communicate its 50 years of experience to all sectors of the sport, to protect the outstanding safety record of karting, and to maintain the integrity of the sport, IKF takes no responsibility for the maintenance of, inspection of, nor individual responsibility for each owner/driver maintaining or operating their own karts. This Rule Book seeks to enhance the sport of karting, with standardized mechanical components and overall safe operation practices. It is required that each individual use common sense, take personal responsibility for the maintenance, inspection, and operation of their kart for the safest and most enjoyable karting experience. Your attempt to rely upon and/or comply with the Rule Book is with the express assumption of all risks of the sport of karting, and does not in any way provide a basis for attempting to hold IKF liable for any damage or injury. Due to specific local conditions for sanctioned IKF Races, the Race Director shall be empowered to permit minor deviation from any of the rules and/or regulations herein, or impose any further restrictions that in his opinion do not alter the minimum acceptable requirements. No expressed or implied warranty of safety shall result from such alteration of rules and/or regulations. Any interpretation of a deviation from these rules and/or regulations is left to the discretion of the local track officials. Their decision is final. —The IKF Board of Directors SECTION PAGE 300 ROAD RACE 301 Chassis SPecifications IKF MEMBERSHIP CARDS 302 Enduro/Laydown Chassis Rules 303 SuPer Stock Bodywork Rules 100 INTRODUCTION & GENERAL REGULATIONS 304 ICE-IKF Intercontinental E Rules 101 IKF Rule Removed 305 Formula Kart ExPerimental (FKE) 102 Rules and Policies 306 SPrint Classes 103 IKF Rule Removed 307 Road Race IKF SPrint Sit-Up Seat 104 Eligibility 308 Road Racing Procedures 105 Safety 309 Road Race Licensing 106 Pit Rules 310 Road Race Scoring 107 Hot Pit Rules 311 Road Racing Grand Nationals 108 Driving Procedures 312 IKF Road Race Grand Nationals Schedule 109 Flags 313 SPec Tires 110 General Driving Procedures 111 Engines 400 SPEEDWAY RACING 112 General Chassis SPecifications 401 Chassis SPecifications 113 Officials 402 2-Cycle National Championship Classes 114 Penalties 403 4-Cycle National Championship Classes 115 IKF ExPert Driver 404 2-Cycle Grand National Schedule 116 IKF Hall of Fame ExPerts 405 4-Cycle Grand National Schedule 406 Race Procedures 200 SPRINT RACING 407 Race Format 201 Chassis SPecifications 408 Scoring 202 Clutches 410 SPeedway Midget Rules 203 Aerodynamic Regulations 411 SPeedway Midget Grand National Schedule 204 Fuel System 205 Chain Oiler 420 CHAMP KART RULES 206 Number Panels 207 2-Cycle National ChamP’ Classes 430 SPEEDWAY KID KART RULES 208 2-Cycle Class Regulations 209 4-Cycle National ChamP’ Classes 450 PAVEMENT SPEEDWAY 210 SPrint Race Procedures 451 Chassis SPecifications 211 Race Format and Scoring 452 SPeedway Pavement National ChamP’ 212 2-Cycle Grand National Schedule Classes 213 4-Cycle Grand National Schedule 453 Grand National Schedule 454 Race Procedures 250 SHIFTER 455 Race Format 251 SPrint Shifter National ChamP’ Classes 456 SPeedway Pavement Scoring 252 Class Specifications 253 Engine Substitutions 500 TECHNICAL INSPECTION 254 Shifer Kart Starting Procedures 500 Technical Section Introduction 255 Grand National Race Format 501 Scope of Tech Inspection Manual 256 Grand National Fuel 502 Pre-Race InsPection Area 257 SPrint Shifter License Program 503 Pre-Race Technical InsPection 258 Grand National Schedule 504 Post-Race InsPection 505 Final InsPection Area 506 Identification Tag 676 IAME CuP Rules 507 Protests 508 APPeals 700 4-CYCLE TECH INSPECTION 509 2-Cycle Tech Tools 700.1 Header and Muffler 510 Mufflers 700.2 SPecial Notes 511 IKF 2-Cycle Legal Exhaust Systems 700.3 Junior Restrictor Plates 512 Ignitions 700.4 Stock Class Air FIlter Adapter 700.5 Fuel and Oil 600 2-CYCLE TECH INSPECTION 700.6 Fuel Tech Procedures 601 SPrint, SPeedway, and Road Racing SPec 701 Stock Briggs and Stratton Rules Fuel Program 702 Tecumseh Controlled Stock Engine Rules 602 Technical InsPection Procedures 703 Tecumseh Controlled Stock InsPection 603 General Notes Procedure 610 Obsolete Engines 704 IKF Briggs Class Rules 615 IAME KA100 Reed Valve 100cc 705 SuPer Stock Rules 616 Stock 100cc Piston Valve Engine 706 Limited Modified Engine Rules 617 Yamaha KT100S 707 Briggs Modified Engine Rules 618 DAP T-50 Piston Port 708 Open Engine Rules 619 TKM BT-82 Piston Port 709 Star Class Engine Rules Komet K-71 Piston Port 710 Tecumseh MotorsPorts H-50 Stock Engine 620 KPV Rules 621 PCR PP-100 Piston Port 711 IKF SPec Limited Engine Rules 621.1 Comer Piston Port 712 Briggs Blue Wazoom Engine Rules 621.2 FIA/FMK 100cc Piston Port Engines 713 Senior SPortsman Engine Rules 622 Comer K-80 80cc Piston Port 714 Honda GX140, GX160, and GX160K1 Engine 622.51 Comer C-51 Piston Port (Kid Kart) Rules 623 Intake and Exhaust Restrictions (Junior and 715 Animal SPortsman Rules Sportsman Classes) 716 Briggs Animal Rules 624 Engine and Part Homologation, 2-Cycle 717 IKF Briggs World Formula Engine Rules Procedure 718 Briggs Gas Animal Rules 625 Homologated Engine Renewals for 2009 719 IKF Ltd Mod Briggs Animal 626 Pure Engine Class Homologation 720 Briggs Animal Blue Wazoom Rules 721 Briggs Local Option 206 Rules 650 SHIFTER TECH SPECS 722 Stock International Class Engine Rules 651 Rules Common to all IKF Shifters 723 SuPer Stock International Class Engine 652 Formula CR80/85 Cadet Rules 653 Formula 80/85 Junior, Senior, Limited 750 Procedure for 4-Cycle Engine and Parts 654 Formula 125 Homologation 655 ICC (FZ) Engines 656 Formula 125 Ltd., Formula 125 Ltd.

Karting is a sport designed for the fun and enjoyment of the whole family. There have been attempts to test the rule by deviating from this purpose for which the basic sport is intended. The Spirit and Intent of the rule is going to be the standard by which karting will be guided. Event officials are authorized to decide if an equipment change or design is an attempt to “beat” the rules. They can and will disqualify an entry in violation of the Spirit and Intent of these rules. Any official or representative shall have the right to correct conditions not in compliance with the Spirit and Intent of these regulations. The International Kart Federation (IKF) takes pride in its long record of achievement as a governing body for the sport of kart racing. In recognition of the need for controls over the sport, the International Kart Federation has published rules for competition since November 21, 1957. Throughout this time, the objectives of the Federation have been the same: to foster strong and fair competition; to provide reasonable rules for the various types of competition; to administer the competition program with impartiality, and to reduce the hazards associated with this sport. Entrants, drivers and participants in general are required to be fully conversant with these regulations and any supplementary rules or instructions governing an event, and are, by reason of their entry therein, bound by such regulations, supplementary rules, or instructions. It shall be the duty of every IKF member to conduct themselves, while rePresenting the Federation, in a manner that shall not be prejudicial to the Federation, nor bring unnecessary criticism on the Federation. The prime responsibility for the condition and oPeration of a kart or any other vehicle in comPetition rests with the owner/driver.
