Can someone explain this to me? I'm reading about it right now, but I don't fully understand it.

Yeah I just didn't know all the names of the parts at first it made perfect sense the second time i read through. Your pictures would have saved me 10mins of reading though thanks :)

What's the point of inverted forks, though?

Less weight to rebound, more weight up top, plus it lessens the overall weight because of the kinds of connectors needed...

It puts the stiffest part of the fork at the top where it would normally show the most flex. It also allows for a reduction in the length of the inner slider.

Basically it makes a stiffer if somewhat heavier fork. Less flex means fewer problems with inconsistancies in the road whilst the bike is leaned over. The average rider would never notice the difference, but a racer will. Which is why you'll find them on basically every race bike currently in production.

If you want to look at a bike with crappy front end suspension the Yamaha V-Max is a good example.
Of course I'm generalizing from a single example here, but everyone does that. At least I do.

I understand that it is also done to help lighten the weight of the suspension. By inverting the forks, there is less weight on the suspension components that move during a bump. Therfore the bike can more quickly and easily return to it's "normal" state after going over a bump.

I hope I got that right! ;)

All the race bikes...and the occasional cruiser.

My VTX 1800 has inverted forks.

It's also a reduction in unsprung weight, which can greatly improve handling during a turn.

Yes Ven... and the occasional cruiser. If memory serves so does the antiquated Suzuki Marauder.
