This class will be a points class at all Manufacturer’s Cup events.

It will be the rider’s responsibility to monitor his or her points earnings after every event. All requests for points adjustments must be made in writing to info@mancup.info within thirty days of the points posting for the event in question on all events EXCEPT the Finals. For the Finals ONLY, all requests for points adjustments, again, must be made in writing to info@mancup.info and within TEN days of the points being posted.
