Aprilia RS 125

Low down the RS is rideable, if a little slow. Hit 8,000rpm and it all changes; the exhaust note switches to a highpitched waaaa and the little RS flies, until it runs out of puff at around 11,000rpm where it simply stops revving as though it cant draw enough fuel in. Handling is razor sharp and the brakes have more than enough bite for this 125kg flyweight.
