What are some advantages of a belt drive?

Hi

Thanks for the question, here's the answer I found:

There are many more advantages to a belt-drive system than ease of use:

> A belt drive can increase power over a timing chain through less frictional loss, more precise timing and smoother valve train motion.
> It can eliminate windage caused by the timing chain and gears running in oil.
> A belt drive also isolates the crankshaft’s torsional vibrations from the camshaft better than a chain (and certainly better than gear drives, which can amplify crank harmonics).

Think of it as a second harmonic damper for the rotating assembly.
