The brawl had broken out at the Perth Motorplex on October 3 and left Silvestro and Smith with injuries.

All four men had kept quiet during the CCC hearing and were subsequently charged with contempt for refusing to be sworn in to give evidence and insulting corruption commissioner Len Roberts-Smith.

The lawyer for the four bikies said they refused to provide evidence to the CCC because they feared retribution should they co-operate.

On Friday, Chief Justice Wayne Martin noted that the "persistent defiance" of the men to assist the commission in its investigation into organised crime was extremely serious.

Chikonga, 24, Silvestro, 42, and Smith, 37, were all given two-year sentences for refusing to answer questions or be sworn in to give evidence.

Allbeury, 29 and a new father, was sentenced to two years and three months for not only refusing to give evidence but insulting Commissioner Roberts-Smith during the hearings.

As the sentence was handed down, Allbeury angrily told Chief Justice Martin: "You can f***, you're a f*****g spastic, you live in a dream world. You live in a fairy world. You don't have any idea about the streets".

As he was ordered out of the courts he threatened to "knock out" a security guard.

Due to the seriousness of the offence, Justice Martin said it was appropriate for a penalty to be imposed in order to deter future contempts of court.

There would also be no eligibility for parole for the four men.
