We like the Aprilia Tuono V4 and the RSV4 a lot, but we like the idea of their scaled-down versions even more. And the bike maker hasn’t disappointed us at all, as it showcased the RS150 and Tuono 150 at the ongoing Auto Expo. These bikes are powered by a 150cc, liquid-cooled, fuel-injected motor that produces 18hp at 10,000rpm and 14Nm of torque at 7,500rpm. Along with racy and aggressive bodywork, the Aprilia duo will also boast excellent dynamics and will certainly take the fight to the Yamaha R15 V3.0’s doorstep. We can’t wait; can you?
