As of 2017 (TBA 2018), the minimum standard for accepted helmets at BMW Club of Canada, Trillium Chapter driving events will be SA2010. Since SA2020 helmets do not become available until the end of the year, this is the final year we will accept SA2010 helmets. Please do not confuse M20XX with SA20XX. M is for 'M'otorcyle, not 'M'otorsport. We do not accept motorcycle (i.e. M-rated) helmets. For more information on helmet standards, please see the web site of the Snell Memorial Foundation at http://www.smf.org/stds.
