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 Regionís intention to create a fun, safe and level playing field for both Junior and Adult Kart Drivers. The following material summarizes the karting rules, sets out the guidelines, and rules that govern the karting program. In order to promote and maintain the Regionís 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 2013 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 Regionís primary concern. Before being allowed to compete, a Junior Driver must be approved by the Regionís Youth Steward. A Junior Driverís 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 JB. Junior Drivers from the ages of 12 up to their 18th birthday (or through 17) compete in JA. 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 JC. 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 JB 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 Driverís meeting and course walk, complete at least one additional course walk and a workerís assignment as approved by the Regionís Youth Steward. Failure to provide a waiver or attend the driverís 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 2012 rulebook.
Kart Eligibility - Ohio Valley Region uses the Solo Rule Book to determine a kartís eligibility. All Junior Drivers and their families must be familiar with the rulebook and present a kart that complies with the rules for JA, JB or JC 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 ĺ" in stroke, with a high-contrast color and background.
JA & JB Karts - are described in SCCA Solo Rule Book, Section 19, 19.1 and 19.2 on pages 270-273. 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 junior 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.
JC Karts - Karts must meet all JA/JB requirements plus, "BabyKart", "Kid Kart" and Cadet size chassis racing style chassis only.† Comer 50/51 engine with factory supplied carburetor & exhaust.† Effective 03/01/2012 - Maximum size for front tires is 4.60/10.0-5.† Maximum size for rear tires is 5.00/11.00-5.† Tire brand and compound is restricted to the MG Brand - HZ model or MG "Red".† Also, "Cadet" designated tires from any manufacturer are allowed.
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 competitorís request. Also, note that specific tire sizes are required (6.00 x 11.0-5 Rears; 4.60 x 10-5 Fronts), which may be smaller and narrower than those allowed in adult classes. Only the MG HZ "Red" tire will be the spec tire for all Formula Junior classes

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: KM and KM1. 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.
KM1 - Drivers must be 16 years of age or older. This class is regional only to allow "non-shifter" karts a competitive separate class. †Engines must be either a) mass produced single cylinder two-stroke engines not to exceed 125cc or b) mass produced single or twin cylinder, four-stroke engines not to exceed 250cc of total displacement. No prototype, preproduction, "works type" motors or road race engines are allowed. Shifter or gearbox type motors are prohibited. Karts with engines under this specification must run at a minimum weight of 360 lbs.† Karts running in this class must meet all other rules as outlined for KM class in the current Solo II rulebook.
KM - Drivers must be 16 years of age or older. Karts eligible for this class include those specified in the 2012 Solo rulebook. 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 may be allowed, as outlined in the Youth Drivers section, above.
This document is meant to be a quick reference summary of the current SCCA Karting program.† While we make every effort to be as accurate as possible please note the current SCCA Solo II rulebook will always take precedent over any information contained herein.
