The probationary period is intended to give competitors an opportunity to support the class and show that it is viable.

9.3 TECHNICAL INSPECTION

a) All turn signals, luggage racks and mirrors must be removed. Non-essential brackets, braces, grab rails, and chain guards may be removed. Centerstands and sidestands must be removed. b) Parts of the motorcycle that have sharp edges or corners and that present a cutting hazard must be smoothed or covered with at least 1/8-inch of rubber or other approved padding. These parts include, but are not limited to, foot controls and sidestand lugs. c) The motorcycle seat or fender must extend rearward beyond the line drawn vertically through the rear axle. d) If used, oil coolers must be securely mounted in a protected area. Manufacturerapproved oil lines or properly installed aftermarket lines and fittings must be used. Oil coolers, if used, must be frame-mounted (no fork-mounted oil coolers). e) An unbreakable catch tank or reservoir of at least six-ounce capacity must be provided for any breather hoses venting the following: cambox or top end, crankcase, primary, gearbox, oil tank, and radiator or coolant tanks. Catch tanks must be situated so they will not normally overflow unless more than two-thirds full. Liquid-cooled machines must use only water or “WaterWetter” as a coolant, and a separate six-ounce catch tank must be provided. f) Oil containment. Oil containment systems are required on all road racing machines. Oil containment pans on wet-sump engines must be designed to hold the capacity of the engine sump with nominal reserve. Material used must be durable, fastened safely, and removable for inspection, if required. All machines fitted with split or two-piece fairings must be fitted with an internal oil containment system. The pan must have a retaining dam at the rear. Two-stroke and dry-sump machines must use a pan with a minimum capacity of one quart, or approved oil-absorbing material covered with an impermeable layer of material and a screen backing and fastened securely. Oil-absorbing material, securely retained in the bottom of the pan, is strongly recommended. All oil containment systems are subject to approval by technical inspection.
