Aprilia’s new 660 motor engine specifications

Aprilia's new 660 motor engine specifications

Aprilia’s new RS660 is the Noale association’s first new machine in quite a while, connecting a vast opening of their sports bike range between the RSV4 1100 and the RS50 and RS125. It likewise has a pristine motor… well, kind of.

The fluid-cooled 8v, 659cc equal twin is really the front portion of the V4 1100cc motor from the RSV4 and Tuono, with all their elite resources still unblemished. It has new housings and castings obviously, yet it’s as yet a superbike protuberance at its center. Admissions, ignition chambers, and internals are planned and fabricated utilizing loads of abbreviations, for example, CFD (Computational Fluid Dynamics), CAE (Computer-Aided Engineering), and FEM (Finite Element Method).

The motor highlights variable tallness consumption trumpets, 48mm choke bodies, emptied camshafts, a smooth six-speed gearbox with an up/down quick-shifter, and a slip-and-help grasp. It utilizes a similar 81mm bore as the V4, yet a more extended 63.93mm stroke, up from the 1100s 52.3mm.

Its new high-pressure (13.5:1 proportion) chamber head is tuned for additional low and midrange snort. Pinnacle force is 49lb-ft @ 8500rpm and it makes 80% of it at simply 4000rpm and 90% at 6250rpm – ideal for genuine riding. The Euro5 agreeable equal twin makes a class-driving 99bhp @ 10,500rpm (or 94bhp for the A2 permit restrictable form), which is sufficient to push the RS660 along at an insidious pace of bunches, particularly as it weighs nearly nothing (simply 183kg wet) and it’s unpredictable terminating 270° wrench supplies it with the hard-edged thunder of a 90° V-twin when you whip it.

The motor is inclined forward in the casing to get the warmth far from the rider and the twofold cleaned fairing brings are planned down to quicken air between the boards for more effective cooling.

In any case, not at all like a superbike that has so much execution, it’s difficult to utilize more than a small amount of it out and about, the RS660’s capacity isn’t over the top and it’s that, alongside its comfortable riding position, that makes it so natural to ride and get the best out of at typical rates.
