Footage from a helmet camera worn by the biker shows the car turning in the road, which causes the motorcyclist to slam on the brakes, but not quickly enough to avoid a crash.
He claims that his bike was written off and the insurance company ruled that he wasn't at fault, but the opinion of those who've seen the footage isn't so clear cut.
While many support the biker, some have said the whole thing is a bit tricky.
Sharing the video to Facebook group 'Dash Cam Owners Australia', the motorbike rider wrote: "Melbourne, Victoria, March.
"Exit roundabout, travelling Northbound up Lincoln Rd in Essendon.
"White Mercedes CLA pulled out from curb to do U-turn, cutting me off. No room to swerve so I hit both brakes but still collided.
"Head was a daze, full of adrenalin. Driver pulled over. Good Samaritan in ute [Aussie slang for a utility vehicle] helped move bike to side of road.
"Had x-rays done afterwards, all okay now. Driver claimed I was at fault. Insurance took a bit over a month to deem motorcycle a write-off, I did nothing wrong and pay me out.
"Bike was 20 days old."
He concluded: "Be careful out there."
Many viewers were quick to share their own experiences, and to chime in with support for the biker.
One said: "Same thing happened to me in NSW and the car driver was charged with negligent driving.
"As a motorcyclist I ride as if every other road user is hell-bent on killing me. I'm still alive, but only just!"
Another said: "Clearly the cars fault turning into oncoming traffic with [an] obstruction, but this does show as a rider you have to constantly be looking out for hazards and incompetent drivers, if you can lose your license for 31kms and over why not for causing an accident like this where someone actually got hurt?"
However, not everyone thinks it was quite so straightforward.
One person commented: "It's a tricky one.
"Both motorists had no vision of each other because the motor home was locking both [of] their line of sight.
"But the fault still lies with the car driver. If you do a U-turn or pull out into a lane with oncoming traffic, you should wait till it's clear.
"The bike rider would probably have enough time to slow down if the motorhome wasn't blocking him from seeing the car till the last minute."
Another said: "Looking at the video, why would you ride that quick with a lot of vehicles around and why wouldn't you try to avoid the car... Obviously not paying attention."
