We know what you're thinking...
Surely if the standard RSV4 with 200bhp struggles to be reliable...with 250...erm...it's gonna explode so hard it'll register on the richter scale, right?
Well you're probably right. But who cares when it looks this good. Aprilia has unleashed this extra power thanks to the use of pneumatic valves and an 81mm overbore that's equivalent to the MotoGP machine. It'll be utter lunacy and with the Aprilia electronics package it'll probably be pretty usable to boot
Pneumatic valves give this motor a screaming redline and 250bhp power figure
So how much is it?
Well, if you have to ask... (we'd guess it'll be around £170,000)
Considering the level of spec and the engineer Aprilia will send along to your trackays, that's not too bad. We'll take three.
