Funnily enough passed under the radar a bit, this update of Aprilia’s smallest, because admit it; they look great. The Italian duo has recently been completely up to date with a new block, new ECU, renewed styling and a fully digital dashboard.
Both 125cc’s were fitted with a new liquid-cooled and of course Euro5-compliant four-valve single-cylinder; with new cylinder head, redesigned combustion chamber, new intake and exhaust channels and a new iridium spark plug. Also new: camshafts, the complete air intake plus air filter, while the throttle body has been positioned higher. The exhaust line was redesigned and got a more efficient catalytic converter. All this should result in an ‘even more robust’ torque curve, according to Aprilia, while maximum power (15 hp, as is usual in this class) is reached at lower revs. That should benefit consumption, thanks in part to a new Marelli MIUG4 ECU. Naked numbers: 15 hp @ 10,000 rpm and 11.2 Nm @ 8,000 rpm.
The design of both 125cc’s is clearly based on that of the big brothers RS660 and Tuono 660, and we can’t be sorry about that. The head fairing of the Tuono became slightly more compact, while the RS sees its clip-ons placed 18 mm higher for extra comfort. Although he does not sacrifice sportiness, on the contrary, sporty driving is even more encouraged with a (albeit optional) quickshifter, which is also available for the Tuono. The dashboard is now a fully digital one with (obviously) bluetooth connectivity, a USB port under the seat is optional. Radial-mounted brakes with steel-braided brake lines are now assisted by two-channel Bosch ABS, the tank capacity remained the same (14.5 litres). Seat height of the RS is 820 mm, the Tuono is slightly lower at 810 mm.
The RS is available in Aprilia Black and Sintesi Blue, the Tuono is available in Aprilia Black, Lightning White and Arrow Grey. Prices are roughly in line with the competitors in this 125cc class: the Aprilia RS125 costs € 5,545 in Belgium and € 6,035 in the Netherlands, for the Tuono you pay € 5,145 in Belgium and € 5,635 in the Netherlands.
