CLAD in black leather vests worn over pink t-shirts, they pull into Spinnaker Park with engines revving.
They are the Chrome Divas - an all-female social motorcycle riding club.
And they're the first Australian chapter to join the organisation, which began in 2002 in the US.
Chapter director Janelle Fisher said she decided to launch the Chrome Divas in Gladstone in February this year, because, "I've got girlfriends who ride bikes".
The Divas plan to participate in the Bums on Bikes charity ride for cancer on October 23.
Their monthly meeting is on tonight at the Club Hotel.
All women with an interest in riding are invited to attend.
Dinner starts at 6pm.
