In my case the costs of insurance is no match for the school fees you pay when you didn't have it.
In 2012 I bought a little Honda XR125 for R 10 000, to do one "small bike trip" to the Karoo. On the 4th day I had it I was attending to some work in the morning and I took the bike because I wanted to ride it to the municipality to do the whole transfer.
Got in a moer of a big accident. This is where the trouble started, all because it wasn't insured.
Luckily I was conscious enough to ask my brother to phone the right people who could come fetch the bike and take it to a mechanic so long. Two months went by before I was able to go and view the bike and assess the damage. About that same time I went to see a lawyer about putting in an RAF claim....a week after that the sheriff arrived with a summons.....I'm getting sued for damages to the truck....R 35 000 worth of damages to the truck....and my XR was only worth R 10 000. Had I had insurance, I would have had none of the worries or the hassles.
The legal battle to get those people off my neck took as long as the whole RAF claim....3 years. It had to be proven that the accident wasn't my fault, because if I admitted or even settled the case with the other party I then admit some guilt in the incident....which would spoil my chances of a RAF claim.
I had the inconvenience of having to get quotes for the damages to the XR simply to oppose the R 35 000 claim for he truck. In the end, after a year of legal battle we got to a stage where it was safe for me to start fixing the XR. Damage wasn't so bad...seems I took the hit for the bike....(medical costs to fix me amounted to over R 400 000....thank you medical aid

) and I fixed the XR with Startline parts for around R 2000.
The bike didn't look like a new one and I could only sell it for R 7500....I was glad to recoup some money lost, but I still lost some.
I have therefore paid the school fees of not having insurance (and I consider myself fortunate that I came off relatively cheaply) and can only give the following advice...
Our bikes & lifestyles are expensive luxuries. Luckily we all know we don't need the latest, greatest bike to have fun on.
Ride the bike you can afford and make sure that whatever you ride is insured with the best insurance you can afford
