Cause there does not exist any bike that provides anywhere near the fun for the dollar.
They're a quarter of the price of a good sports 250, make sexy two-stroke noises, are mechanically very simple - so you can do a lot of work on them yourself, they're pretty much the most flickable thing on the planet bar a 125GP bike, they're very narrow which is great for splitting, they are just one hell of a little machine.
A major factor in me deciding to look for an RG was Two Smoker's apprenticeship on one. He's proven that when ridden properly, they can give many larger bikes The Learn through tight sections. It doesn't hurt to be a race god amongst mortals like TS, but the bike is up to the challenge.
The two-stroke-ness is a big plus. It teaches you good throttle control around town. With a kick-start, you are never susceptible to a flat battery. Indeed, I rode it for over a week with the battery completely disconnected.....(I thought it was just flat lol). Not that great on gas though for a small bike, I got 175Ks out of my last 10L... :| Oil is also a factor, adding another ~35% on top of fuel *cough* depending on how it's ridden.
The only downside I think it has is pretty shit ground clearance. Scraping pegs is a non-event. Maybe that could be turned into a plus, forcing one to develop good hanging-off technique?
Eat the riches! Eat your money! The revolution will be DELICIOUS!!!
