A motorbike rider has allegedly been clocked by police speeding at 300km/h on a Victorian freeway.

Officers first detected a motorcycle speeding along the Princes Freeway in Lara about 10pm yesterday.

The police helicopter was called in a short time later as the the rider weaved through streets in North Geelong, Corio and Ocean Grove, allegedly hitting speeds of up to 300km/h.

The motorcycle can be heard, and briefly seen, on CCTV from a nearby home flying down a local road.

It came to a stop outside a home on Christies Road in Leopold about 10.30pm and a 27-year-old man was arrested.

He has since been charged with dangerous conduct endangering life as well as several other traffic offences.

The man was bailed to appear before Geelong Magistrates' Court on May 8.

The motorcycle was impounded at a cost of $1305.

The police pursuit coincided with a Victorian Liberal Party pledge to crack down on offenders involved in car chases if they are elected at the November state election.

There's currently three offence types related to police pursuits, with varying penalties ranging from fines to jail time.

The Liberal Party pledged to add a fourth offence, which would lower the threshold to lock offenders up.

The police union threw its support behind the proposal.

"Their punishment should better reflect the serious danger their actions have placed our police and the community in," police union secretary Wayne Gatt said.

"We cannot have people where they continue, like last night, to drive on highways and freeways at 300km/h, putting the community at risk without consequence," shadow police minister Brad Battin said.

Transport Infrastructure Minister Gabrielle Williams called the pledge a "back-of-the-envelope policy".

"To be frank, this is already effectively law in Victoria, so it's a bit embarrassing for Jess Wilson and the Liberals that this is the policy position they've come out with today," she said.
