  MSA ROPS Bulletin - October 2017 Back to results

The October 2017 MSA bulletin details new requirements for Roof and Windscreen Pillar Reinforcement in vehicles competing in Stage Rallying. We have attached an abridged copy showing the sections relevant to ROPS and all other sections have been greyed out for clarity.

To determine whether your vehicle is affected, please review the following:


  • The changes only apply to vehicles involved in Stage Rallying which are going to be log booked after the 1st January 2019.
  • Any vehicle that is already log booked, or log booked in advance of 1st January 2019 is compliant and will continue to be compliant indefinitely after this date.
  • Vehicles that have a HRVIF (Historic Rally Vehicle Identification Form) are exempt from the alterations described.
  • Any vehicles used in a discipline outside of Stage Rallying (e.g. Circuit Racing) are not currently included in this bulletin.


The summary of requirements for affected vehicles is as follows:

  • ROPS will need Roof Reinforcement - Reference Section K, Appendix 2, drawings 10(a) to (d)
  • ROPS will need Windscreen Pillar Reinforcement – Reference Section K, Appendix 2, drawing 63 and Section R 48.10.1 (b)


For ROPS designed to the MSA Blue Book specification (as opposed to FIA Appendix J regulations or being FIA Homologated) if members are to be added to an existing ROPS then the specification depends on the age of the vehicle, taken from Section K, 1.4.1:


Minimum Dimensions (Ø in mm)

a) Mandatory tubular members

45 x 2.5 (1.75” x 0.095”) or 50 x 2.0 (2.0” x 0.083”)

38 x 2.5 (1.5” x 0.095”) or 40 x 2.0 (1.6” x 0.083”) (For roll cages/bars approved prior to 1.1.95).


The MSA have also allowed the amendment of existing FIA homologated ROPS designs to include the addition of these additional members. Alterations to an FIA homologated ROPS design do not have to meet the above material requirements but should match the material diameter and thickness of adjoining tubes.

Please contact Safety Devices in advance of making any alterations to your cage as modification of an existing design may invalidate any FIA homologation already present. Safety Devices will be working on updating existing designs for new orders and processing the necessary amendments with the FIA, where applicable.

Please remember that if your vehicle is not used in Stage Rallying, or if it is/will be log booked before 1st January 2019, these changes will not affect the compliance of your ROPS.
