CRMC Sidecars - Developing Period 4 for 2019

Unread post by steve reilly » Fri Jan 25, 2019 2:03 pm

Hi All - See below the announcement on the CRMC Website, changes for the 2019 Season. :) :o 8-)

CRMC Announcement

We are also pleased to announce development of the Sidecar Period 4 rules. Sidecar rules have remained static for several years, so this change allows certain production and Grand Prix 2 stroke engines (plus some some 8-valve 4-stroke engines) to be used:

Production Based Engines (all limited to 750cc):
• Suzuki T500 air cooled twin cylinder two stroke,
• Suzuki GT750cc water cooled three cylinder two stroke.
• Suzuki GS 750cc 8 valve double OHC air cooled four cylinder four stroke.
• Kawasaki 500/750cc air cooled three cylinder two strokes.
• Kawasaki Z2 750cc 8 valve DOHC air cooled four cylinder four stroke engine.

Grand Prix Engines (limited to 500cc):
• Konig 500cc Water Cooled Flat Four Two Stroke.

Note – Other post 1972 (1970’s) engines may be eligible by request and discussion with the Sidecar Eligibility Officer

If you have any questions, please contact one of the eligibility officers, who will be glad to help.

I have extracted the relevant bits out of the 2019 Eligibility Book, the whole thing is available on the CRMC website.

CLASSIFICATION - Sidecars will be classified by Engine Type into "Period 1", "Period 2",“Period 3” and for the 2019 season “Period 4” is being developed.
