Back in 2010, Aprilia released a Biaggi replica RSV4. It made 200bhp and cost €50,000. Only a handful were ever made. Slightly more accessible is this Aprilia RS4 125 replica being made by Aprilia UK. It makes 15bhp and costs just £4,299, bringing with it a Pirelli Diablo Rosso IIs, wavy discs and a quickshifter as standard. Might sound like all that pales in comparison, but if I were 17, a bike like this would literally be the stuff of dreams.
