The Ducati’s 849.4cc V-twin Testastretta engine has new cylinder heads, revised ports, hot cams, new pistons (increasing the compression ratio from 12.1 to 13.2:1) and new elliptical throttle bodies, up from 56mm to 60mm. Power is increased from a measured 122bhp to 126bhp over the old 848, which might not sound much but it’s given the 848 Evo a far more aggressive edge. The 848 Evo loves to be revved and when you do, it rewards you with savage acceleration. Being a big V-twin, you can still ride the torque, be lazy with the gears and cover ground almost as fast.
