The good news is Aprilia has given the 2021 RSV4 and Tuono some major updates. The bad news is these two photos are all we currently have of the two bikes.
RSV4 and RSV4 Factory
Nonetheless, let’s start with the updated RSV4. Judging from the sole picture we have here, one could think that they’re looking at Aprilia’s latest darling, the RS660. This isn’t a coincidence. Traditionally, a manufacturer would update its flagship and trickle down its traits downstream to the rest of the product line. Aprilia is shucking those norms, as it fully admits the RSV4 styling is inspired by its RS660 little brother – not that that’s a bad thing.
Borrowing from the wind tunnel lessons learned from the RS660, Aprilia says the new RSV4’s bodywork has “an extremely low aerodynamic resistance coefficient” with increased air pressure in the airbox, which we assume translates into a greater ram-air effect for the engine. A triple LED front headlight unit looks very similar to the one on the RS660, but this one features a “bending” function that lights up the inside of a corner when turning or leaning the bike.
In a move that I personally agree with aesthetically, the winglets seen on the previous RSV4 1100 Factory are no longer appendages sticking out of the side of the motorcycle. Like the RS660, the redesigned bodywork integrates the winglets as part of the double-wall design (not too dissimilar to what Honda has done with the new CBR1000RR-R). In addition to the added downforce, Aprilia says this solution serves the same purpose as it does on the RS660 by channeling hot air away from the rider and helping to improve engine cooling.
Oddly tucked away at the bottom of Aprilia’s press release is the fact the RSV4 gets a new, bigger, 1099cc V4 engine, making it …read more
