2015 FIM CEV REPSOL TM MOTO 2 EUROPEAN CHAMPIONSHIP SUPERSTOCK 600 TECHNICAL RULES 4.6 SUPERSTOCK 600 TECHNICAL SPECIFICATIONS The following rules are intended to permit limited changes to the homologated motorcycle in the interests of safety and improved competition between various motorcycle concepts. EVERYTHING THAT IS NOT AUTHORISED AND PRESCRIBED IN THIS RULE IS STRICTLY FORBIDDEN If a change to a part or system is not specifically allowed in any of the following articles, then it is forbidden Superstock 600 motorcycles require an FIM homologation. All motorcycles must comply in every respect with all the requirements for Road Racing as specified in these Regulations, unless they are already equipped as such on the homologated model. The appearance from both front, rear and the profile of Superstock 600 motorcycles must (except when otherwise stated) conform to the homologated shape (as originally produced by the manufacturer). The appearance of the exhaust system is excluded from this rule. 4.6.1 Motorcycle specifications All parts and systems not specifically mentioned in the following articles must remain as originally produced by the manufacturer for the homologated motorcycle 4.6.2 Balancing various motorcycle concepts In order to equalize the performance of motorcycles with different engine configurations, changes in the minimum weight may be applied according to their respective racing performances. The decision about applying a handicap system to a respective class is taken by the FIM CEV Commission at any time. The application of the handicap will follow the system like described in 18.104.22.168 of the Superbike regulation but will be adapted to this class. 4.6.3 Displacement capacities The following engine configurations comprise the Superstock 600 class: Over 400 cc up to 600 cc 4-stroke 4 cylinders Over 600 cc up to 675 cc 4-stroke 3 cylinders Over 600 cc up to 750 cc 4-stroke 2 cylinders The displacement capacity, bore and stroke (new), must remain at the homologated size. 4.6.4 Minimum Weights The minimum weight for each model is calculated by FIM by determining the “dry weight” of the homologated motorcycle. The ‘dry’ weight of a homologated motorcycle is defined as the total weight of the empty motorcycle as produced by the manufacturer (after removal of fuel, vehicle number plate, tools and main stand and side stand when fitted but with oil and radiator liquid at prescribed level). To confirm the ‘dry’ weight a minimum of three (3) motorcycles are weighed and compared. The result will be rounded off to the nearest digit. The minimum weight for each model will be calculated by reducing the dry weight” of the motorcycle in 12 kg. At any time of the event, the weight of the whole machine (including the tank and its contents) must not be lower than the minimum weight. There is no tolerance on this minimum weight. During the final technical inspection at the end of the race, the selected motorcycles will be weighed in the condition they finished the race, and the established weight limit must be met in this condition. Nothing may be added to the motorcycle. This includes all fluids. During the practice and qualifying sessions, riders may be asked to submit their motorcycle to a weight control. In all cases the rider must comply with this request. The use of ballast is allowed to stay over the minimum weight limit and may be required due to the handicap system. The use of ballast and weight handicap must be declared to the FIM CEV Technical Director at the preliminary checks. 4.6.5 Number Plate Colours The background colours and figures (numbers) for Superstock 600 are yellow background with black numbers: The sizes for all the front numbers are: Minimum height: 140 mm Minimum width: 80 mm Minimum stroke: 20 mm Minimum space between numbers 10 mm The size for all the side numbers is: Minimum height: 120 mm Minimum width: 70 mm Minimum stroke: 25 mm Minimum space between numbers 10 mm The allocated number (& plate) for the rider must be affixed on the machine as follows: ● once on the front, either in the centre of the fairing or slightly off to one side. The number must be centred on the white background with no advertising within 25mm in all directions. ● once on each side of the motorcycle. Alternatively, once across the top of the rear seat section with the top of the number towards the rider. The rear and side numbers are optional. The preferred location for the numbers on each side of the motorcycle is on the lower rear portion of the main fairing near the bottom. The number must be centred on the white background. In case of a dispute concerning the legibility of numbers, the decision of the FIM CEV Technical Director will be final. 4.6.6 Fuel All engines must function on normal unleaded fuel with a maximum lead content of 0.005 g/l (unleaded) and a maximum MON of 90 (see Art. 2.10.1 for full specification) Only fuel of the current year from the appointed fuel supplier is permitted. This fuel will conform to the FIM Grand Prix specification. Use of this fuel without any addition or alteration is mandatory during all event (free practices, qualifying practices, warm-up and races). 4.6.7 Tyres Only tyres from the official tyre supplier may be used in the Moto2TM FIM CEV and each team must sign a contract. The tyre specifications available at each event will be determined by the tyre supplier. Only homologated tyres in each event are permitted. The maximum number of rear tyres allowed to use during the qualifying practice are THREE (3). During the preliminary technical inspection the teams will be delivered the adhesive stickers used for marking the tyres. Each team will be responsible of marking their tyres. The Technical Stewards may perform random controls during the qualifying practices. If the riders are shown a red flag during the practice, the Permanent Race Direction is allowed to authorize the use of a supplementary tyre. All checked tyres must be easily identifiable with a colour marking or a numerical system. In case of a technical problem, the FIM CEV Technical Director will take a decision about the problem. 4.6.8 Engine 22.214.171.124 Fuel Injection System a.

Protective covers for the frame, chain, footrests, etc. may be made in other materials like fibre composite material if these parts do not replace original parts mounted on the homologated model. 4.6.12 The Following Items MAY BE Removed a. Emission control items (anti-pollution) in or around the air box and engine (O2 sensors, air injection devices). b. Tachometer. c. Speedometer. d. Chain guard as long as it is not incorporated in the rear fender. e. Bolt-on accessories on a rear sub frame. 4.6.13 The Following Items MUST BE Removed a. Headlamp, rear lamp and turn signal indicators (when not incorporated in the fairing). Openings must be covered by suitable materials. b. Rear-view mirrors. c. Horn. d. License plate bracket. e. Toolkit. f. Helmet hooks and luggage carrier hooks g. Passenger foot rests. h. Passenger grab rails. i. Safety bars, centre and side stands must be removed (fixed brackets must remain). 4.6.14 The Following Items MUST BE Altered a. Motorcycles must be equipped with a functional ignition kill switch or button mounted on the right hand handlebar (within reach of the hand while on the hand grips) that is capable of stopping a running engine, the button or switch must be RED. b. All drain plugs must be wired. External oil filter(s), screws and bolts that enter an oil cavity must be safety wired (i.e. on crankcases). c. All motorcycles must have a closed breather system. The oil breather line must be connected and discharge in the airbox. d. Where breather or overflow pipes are fitted they must discharge via existing outlets. The original closed system must be retained: no direct atmospheric emission is permitted. e. Motorcycles must be equipped with a red light on the instrument panel that will illuminate in the event of oil pressure drop.
