D7.0 Group Senior Gearbox     D7.1 Class   125 Europa - Category A Affiliation - Commercial: RPM Motorsport Limited     D7.2 Introduction. The 125 Europa class endeavours to provide an economical Introduction to gearbox karting with the controlled budget of a ‘one make’ low maintenance class, complete with on-board electric starter. The use of exotic parts is restricted and the chassis is limited to an approved design. The engines may only be used in their original standard form other than changes listed in these regulations they shall be sealed to prevent any internal modifications being made. The promoters reserve the right to alter these technical regulations at short notice in respect of safety, fairness of competition, economy and majority competitors wishes. The kart may only be raced with variations described within these regulations, any changes that fall outside these regulations shall be deemed illegal.     D7.2.1 The Europa class has two categories: Europa A is restricted to the MC Motori BAT-3ES engine fitted with an electric starter. Europa B as previously listed in MSA Yearbook     D7.3 Chassis. The only chassis permitted for use in this class is the Europa 125. This is a Top Kart VIPER manufactured to Europa specification. CIK Homologation No. 292/02. The chassis will be fitted with a EUROPA identification plate and serial number. Adjustments to the chassis such as steering geometry (by fitting adjusters), front & rear track, the use of optional torsion bars (where homologated) etc. may be made, but at all times must comply with the Europa specification and general karting regulations. It is the responsibility of the driver to ensure that his chassis remains legal; failure to comply may result in the driver being excluded from the meeting and forfeiting championship points. The kart must be raced complete with CIK style bodywork, the original seat may be changed to any short-circuit upright type and up to two additional rear seat stays may be added. Optional Europa/TopKart 40 x 106mm extended front hubs are permitted. Only the original equipment chassis components or previously approved Europa class racing components may be used unless specifically permitted by these regulations. Additional instrumentation or data logging devices may be optionally used.     D7.4 Engine. The only engine permitted is the MC Motori Bat-3ES to Europa specification, fitted with the original electric starter. For identification all Europa engines will be stamped RPM alongside the Serial Number. The engine may not be machined or modified from the form it was in when it was delivered if it is not specifically stated. The engine must be used complete with all the ancillaries supplied including the electric starter and battery. The engine shall be sealed between barrel and crankcase, an engine that does not carry a regulation seal is deemed illegal. Only authorised service agents will be issued with these seals for fitting after maintenance of the engine. A logbook will be supplied with each engine indicating the engine serial number; it will show the number of the current seal fitted and the service agent responsible. It is the competitor’s responsibility to look after this logbook, ensure the service agent updates it and ensure that his engine remains legal. This logbook must be taken to all Europa race meetings and if requested it must be presented to a race official, failure to provide this book may result in disqualification from the meeting and confiscation of the engine until it is presented. If an engine is found to have illegal modifications then that engine will have its logbook permanently marked to this effect, the competitor will be excluded from the meeting and forfeit all point accumulated in any Europa championship. The service agent who last sealed the illegal engine may be removed from the authorised list. A competitor must not break the engine seal and should an engine be presented for service with a broken or tampered seal it must be fully dismantled, inspected and measured to establish its total conformity with the Europa specification before it may be re-sealed, the owner shall be liable for the costs involved. Only original equipment internal engine parts from RPM Motorsport may be fitted during repair or service. The cylinder head may be removed by the competitor for internal inspection only if necessary, it is their responsibility to ensure it is not modified in any way and is fitted correctly.     D7.4.1   Carburettor & Induction.
