Located in Tampa, Florida is a rare Chesterfield/Biaggi replica Aprilia RS250 that was supposedly shown in the Barber Vintage Motorsports Museum. The bike features Arrow exhaust with the original included. The bike is claimed to be in the condition it was when it left the factory--if it was displayed at Barber, I would imagine that is true. Mileage isn't mentioned in the ad but the asking price is all the money at $11,000. If you're looking for an outstanding RS that has been displayed at Barber, see the Craigslist ad here.
