Helmet question

Yes a M05 rated helmet is good until 2017. M-rated helmets don't have the fire resistant liner like the SA-rated helmets. SA helmets are also a little safer then the M-rated helmets, but for the times you are talking about running the M05 helmet will be perfect. As long as the helmet you buy has a snell rating you are good to go, some motorcycle helmets just have a DOT rating, NHRA does not recognize that rating, it must have a snell rating (snell ratings are the M05, SA05, M00, etc). So any helmet that has a SA05 or M05 rating is good until 2017, any helmet that is rated SA00 or M00 is good until 2012. Hope this helps.
