COMPULSORY RULE for 2021Back & Chest Protectors

105.5. The use of a back & chest protectors is compulsory at all Tarmac events. (ICC December 2019)

105.5.1 Minimum Requirements Use of a Chest and back protector is compulsory and must be clearly marked with the following norms:

a) the back protector must comply with EN1621-2,CB(’central back) or FB(‘full back’) level 1or 2. 18 ©MCUI – Updated December 2019

b) the chest protector must be:

(a) ‘Full chest protectors’ (protector designed as a single piece) and ‘Divided chest protectors’ (protector designed in two separate halves)are permitted. All types of chest protectors (full or divided) must have a minimum protection(total) area of no less than 230cm2 .

 (b) Only protectors and in conformity with prEN 1621-3 (level 1 or 2) are admitted.

 The ‘EN’ stands for ‘European Norm.’ You might also notice armour listed as ‘CE’. The letters ‘CE’ are the abbreviation for the French phrase ‘Conformité Européene’ which literally means ‘European Conformity’. The term initially used was ‘EC Mark’ and it was officially replaced by ‘CE’ Marking’ in the Directive 93/68/EEC in 1993. ‘CE Marking’ is now used in all EU official documents. All of this has to do with the European motorcycle safety standards. America has unofficially adopted these standards, but these are not required by law for street use. In contrast, to ride a motorcycle in Europe, you have to have protective apparel that meets these standards.             (ICC December 2019)
