I'm itching to see what the insurance costs him as the lions share is liability and that's why insurance isn't much less on a motorcycle than a car.

Moto insurance is very polar. Insurance on scooters is practically nothing. Usually less than $100/yr. The factors they look at are: where you live and if the scoot will be licked in a garage at night. Second, they look at your experience. Third, they look at what category your bike falls into. If you're n00b rider, expect to pay a lot the first year. Make it through the first year claim free and rates will drop dramatically. Even back when I only had 15 years riding experience, I paid only $70 for a year's worth of full coverage on a Kawasaki 250. I've seen teenagers, buying the fastest sportbike they can afford, and pay $3000/yr to insure a $9000 bike. That's because the insurance companies know that 40% of them are totaled in their first year.

Actually the liability part cost is very low both for cars and bikes. The highest cost by far is uninsured and underinsured motorist coverage, even more then comprehensive.

It is also something no one can afford to be without in view of all the illegals without insurance as well as the very low mandatory liability coverage.
