Aprilia RS250 (1994-2004)
Exquisitely built no-holds-barred missile, using Suzuki’s RGV250 V-twin engine. Really a 250 production racer with lights: 55bhp means zero low down power, zero mid-range, and a screaming top end. It handles impeccably, and does 140mph. Peerless chassis, the best bits, and one of the most beautiful bikes ever built.
What you’ll pay now £2000-£7000 But should you? For the road, possibly not. As a toy and for trackdays, oh yes.
