The Ohio Valley Region follows the rules and classifications that appear in the most recent edition of the Solo Rule Book. Competitors should note that the current Rule Book might be changed by SCCA during the course of a season. Such changes appear in the Fastrack News section on the SCCA.com web site. It is the Region’s intention to create a fun, safe and level playing field for both Junior and Adult Kart Drivers. The following material summarizes the karting rules and sets out the guidelines and rules that govern the karting program. In order to promote and maintain the Region’s objectives, it may enact Supplemental Regulations.
Formula Junior Driving Program
The rules for Junior Drivers and their karts are found in Section 19 and Appendices G and H of the 2010 Solo Rule Book. Competitors or their families are expected to have a copy of the Rule Book and be familiar with its contents. Additionally a Karting guideline is available at SCCA.com. All drivers who are competing for points must drive a kart for which he or she is age eligible and which is in compliance with the Rules.
Driver Eligibility – Safety is the Region’s primary concern. . Before being allowed to compete, a Junior Driver must be approved by the Region’s Youth Steward. A Junior Driver’s experience, maturity, discipline and skill level will all be considerations in determining whether a child may be allowed to compete, or continue to compete. OVR Formula Juniors age 8 through 11 compete in FJB. Junior Drivers from the ages of 12 up to their 18th birthday(or through 17) compete in FJA. Additionally, OVR has been approved to participate in the pilot program that allows 5-7 year-olds to complete in Cadet Karts with Comer 50 or 51 engines. The OVR class designation shall be FJC. The class in which a Junior Driver competes during the current calendar year is determined by the age that Driver was on December 25th of the preceding year or until their 18th birthday. For example, a Driver who turns 12 in February of the current calendar year may compete in FJB during the current year, because that Driver was 11 on December 25th of the previous year, which is the date that determines eligibility. If, during the season, a Junior Driver has a birthday that would enable such Driver to move up to an “older” class, that Driver may move up at the time of their birthday. Once a Junior Driver moves up, they may not return to the younger group. All Junior Drivers must be an SCCA member, provide a current minor waiver in compliance with SCCA requirements, participate in the Junior Driver’s meeting and course walk, complete at least one additional course walk and a worker’s assignment as approved by the Region’s Youth Steward. Failure to provide a waiver or attend the driver’s meeting or course walks will result in the Driver not being allowed to compete. Failure to complete a satisfactory work assignment will result in disqualification from the event, with no points or awards. An adult must accompany competing Minors for the duration of the event. Formula Junior age is defined as up to 18 in the 2010 rulebook.
Kart Eligibility – Ohio Valley Region uses the Solo Rule Book to determine a kart’s eligibility. All Junior Drivers and their families must be familiar with the rule book and present a kart that complies with the rules for FJA, FJB or FJC in order to compete for points and trophies.
Numbers shall be displayed on the front, rear and both sides of the kart. In no case shall the numbers be smaller than 6” in height and ¾” in stroke, with a high-contrast color and background.
FJA & FJB Karts - are described in SCCA Solo Rule Book, Section 19,19.1 and 19.2 on pages 147-151. The bodywork for a kart must consist of a nose cone and side panels/pods providing adequate driver protection and not giving a competitive advantage. For example, OVR will allow either the “sports car” style intended for WKA Gold Cup or CIK bodywork on a FJ kart, provided that it consisted of a nose cone, side pods and steering fairing. Competitors should pay particular attention to the specified carburetors and exhausts. Due to significant performance differences, the use of a non-specified carburetor or exhaust will result in the kart being prevented from competing.
Safety – Junior Drivers are expected to follow the directions of the Youth Steward and should remain in the area designated as the kart grid at all times. Except during the course walk, Junior Drivers less than 12 years of age are not allowed on the course, in the grid or any hot area, unless they are in their kart for their runs. All Junior Drivers must be able to learn and drive the course, know how to turn off their engine and display the ability to safely drive their kart. All Junior Drivers must wear, a neck brace designed for motor sports, gloves, a full face helmet with shield that complies with Solo Rules section 4.3.1 (current required Snell rating), shoes, socks and a drivers suit, or: full length pants and a long sleeve, abrasive resistant jacket. WKA Technical Manual section 100 provides additional safety information.
Note - Junior Drivers and their families should pay particular attention to the required combined weight of their kart and driver, as SCCA Solo Rules impose significant time penalties for competitors who are underweight. OVR will provide the official scales at each event. As part of the tech inspection, the driver and their kart must meet the minimum weight and may be weighed after every run at the direction of the Youth Steward. This is a pass/fail criteria. Actual weights can be provided at the competitor’s request. Also, note that specific tire sizes are required (6.00 x 11.0-5 Rears; 4.50 x 10-5 Fronts), which may be smaller and narrower than those allowed in adult classes. Tire compound is restricted to Bridgestone YHC or other manufacturer’s models with a durometer reading of 58 or higher. A list of approved tires will be maintained by the youth steward. If a tire is not included on the list, the competitor must provide proof that the tires meet a durometer reading of 58 or higher.
Required Weights
FJK – No specified weight F125- 385 F100-360, with front brakes 385
Adult Karts
In recognition of the significant disparity in performance between some centrifugal clutch karts and shifter and special powered (i.e. Rotax) karts, OVR will provide two classes for karts driven by adults: F125 and F100. All competitors must comply with the Solo Rules. Numbers are to be displayed on the front, rear and both sides of the kart. In no case may the numbers be smaller than 6” height with 3/4” stroke, with a high-contrast color and background. Tire sizes shall be those specified in the Solo rules and SCCA Karting guideline. Tire type, manufacturer and compound are open.
F100 - Drivers must be 16 years of age or older. This class is intended to accommodate Yamaha 100cc, TAG 125cc and comparably powered karts with can or pipe exhausts and a centrifugal clutch. Minimum weights will be as set out in the SCCA Solo Rule Book for the class of kart. The bodywork for a kart must consist of a nose cone and side panels/pods providing adequate driver protection and not giving a competitive advantage. Alternate bodywork styles may be allowed, as outlined in the Youth Drivers section, above. Tire and wheel size, tire type and manufacturer, carburetors and exhausts are open. Centrifugal clutches are required and may be wet or dry.
F125 - Drivers must be 16 years of age or older. Karts eligible for this class include those specified in the 2010 Solo rulebook. Minimum weights will be as set out in the SCCA Solo Rule Book for the class of kart.

Alternate bodywork may be allowed, as outlined in the Youth Drivers section, above. |
