A judge has likened two Finks bikies to crazed teens who want to wear uniforms, ride bikes and join "the posse of a wild west movie, riding off over the badlands".
Fully patched Finks bikies Joseph Muratore and Lee Martin were sentenced to jail in the Victorian County Court on Friday for standing over a man and stabbing him at a factory last year.
Muratore, who was previously a member of the Hells Angels, pleaded guilty to recklessly causing serious injury for beating and stabbing the man in Dandenong on March 6.
Martin, who joined the Finks in his 40s, was charged with assault on the basis of complicity and for refusing to give police access to his phone.
The pair, with senior Finks bikie John Pahoumidis, boxed in Kahan Umit's car in the driveway of the factory to stop him leaving.
They cornered him and spoke to him, before Pahoumidis punched Mr Umit in the jaw.
Mr Umit tried to run away but Muratore picked up a metal stand and threw it at his head.
Muratore then performed a flying kick, hitting Mr Umit in the torso, and crash tackled him to the ground, where he beat and stabbed him.
He held an object to the victim's face and spoke to him, before the group left.
Mr Umit would have died if a bystander had not rushed to find him bleeding on the nature strip and taken action to get him medical attention, the court was told.
"If he had died you would have been facing a charge of murder," Judge Liz Gaynor told Muratore.
"I hope that is extremely clear to you, overall this was appalling, brazen offending."
She slammed the men's involvement with the Finks as being "pathetic", smacking of "the grossest immaturity" and said it made them look like "crazed teenagers".
"I feel as if I am dealing with a pair of immature teenagers who still have to belong to a gang, an army, where you dress up and you go around riding on motorcycles and bash each other up," she said.
"Is it sort of like joining the posse of a wild west movie and riding off over the badlands?"
She handed Muratore, 32, a three-year and four-month jail sentence, and he must serve 20 months before he will be eligible for parole.
He has already served 16 months of this sentence.
Martin, 48, was sentenced to time already served, being 15 months.
Judge Gaynor urged the men, who both have supportive partners and families, to "grow up" and give up the bikie lifestyle.
"That you should end up, in your 40s, in an outlaw motorcycle club, for heaven's sake," she said to Martin.
"And then Mr Muratore, you are not 15, you're not a 10-year-old boy who's collecting magazines about Marvel heroes - you are a man in his 30s."
Pahoumidis pleaded guilty to assault and drug possession for his part in the attack, and will be sentenced in March next year.
