BIDDEFORD — The Maine lawmaker who was the driving force behind the popular pink ribbon breast cancer awareness license plate says the response to creating a motorcycle version has been lukewarm.

The Maine Cancer Foundation says nearly 70 people have committed to the motorcycle license plate. But 500 pre-orders are required for the Bureau of Motor Vehicles to begin production.

Rep. Meredith Strang Burgess, for her part, told the Journal Tribune that she’s setting a deadline of year’s end for collecting pre-orders. If the pre-registrations are gathered, it will take three months for the state to produce the plates before the first ones will be seen on Maine motorcycles.
