Overview[edit | edit source]
Aprilia RS 250 Challenge Cup Edition
It's a
two-stroke sportbike.
It's a racing series.
It's a two-stroke sportbike and a racing series all in one.
It's IROC for motorcycles. Well, maybe AROCH is more like it: American Race Of
Champion Hopefuls. And that's it in a nut. You can't have one without the
other; the RS 250 is available to licensed racers only and the Cup Challenge
is for Aprilia RS 250s only. Sure, you might be able to get your hands on an
RS 250 and never race it but I have to leave you to your own devices for that
one.
Now that Aprilia has come to the States they'd also like to get all of the gray-marketed RS 250s off the streets, so the Cup Challenge series is open to all RSs dating back to '95. When Aprilia wasn't here they didn't have much to fear in the way of liability because if a foolish owner wanted to sue them there wasn't anyone around to sue. Now that they have an office here they're concerned about liability issues in our litigious-happy States, so Aprilia must protect itself up front. So, if you're riding an RS on the street you probably shouldn't try ordering parts from their American distribution center. Hide it or get it to the racetrack. The idea behind the Aprilia Cup Challenge series is to offer riders a reasonably inexpensive place to race where riding, not tuning, can determine the finishing order. Modifications are not allowed. At this writing the chance still exists that the governing body of the series will even transport your bike to each event. Just show up, ride your bike, collect your money, kiss the girl, and go home.
