Members of the Rebels and Finks motorcycle gangs have been charged over two fights between the groups in Sydney's west last month.
Drugs, cash, ammunition and gang paraphernalia were seized during the investigation into the alleged assaults.
Gangs squad Strike Force Raptor had been investigating an alleged assault of two Finks members by Rebels members and an associate at a hotel in Clarendon on June 5 at 6:30pm.
It followed the alleged assault of Rebels associates by Finks members two nights earlier at a hotel in Bligh Park.
Police said they believed both incidents were linked to a previous conflict between the two gangs and are continuing to closely monitor their activities.
Early Wednesday morning police searched homes at Berkshire Park, Mulgoa, Colyton, Ropes Crossing, Bidwill, McGraths Hill and Lalor Park.
Five Rebels members were arrested and police seized two litres of methylamphetamine oil and a small amount of ice, steroids, ammunition, a ballistic vest and Rebels paraphernalia.
A 25-year-old Lalor Park man, a 33-year-old Bidwill man, a 29-year-old Ropes Crossing man, a 22-year-old McGraths Hill and a 34-year-old Colyton man were each charged with affray and participating in a criminal group.
The Lalor Park man was also charged an extra count of affray with possessing a prohibited weapon without a permit.
They were all granted conditional bail.
The Lalor Park, Bidwill and Ropes Crossing men will appear at Mount Druitt Local Court on August 13, while the McGraths Hill and Colyton men will appear at Penrith Local Court on August 17.
An associate of the Rebels, a 33-year-old man from Bidwill, was later arrested at Mount Druitt Police Station and charged with possessing ammunition without a licence.
He was granted conditional bail to appear at Mount Druitt Local Court on August 13.
Police also arrested two members of the Finks at South Windsor on Wednesday in relation to the Bligh Park incident.
The two men, aged 31 and 33, were charged with affray and the younger man was also charged with possessing a prohibited drug.
They were both granted conditional bail and will appear at Windsor Local Court today.
