Battle of the Titans: Aprilia RSV4 RF vs. Ducati Panigale V4 S – Street

We’ve complained about heat from Panigales before, but the new V4 takes the cake. Now instead of one header pipe being routed under the rider’s butt, there’s two! And the frame spars soak up a lot of the engine heat, too, cooking your thighs each time you come to a stop. Often after a long or spirited ride, the Ducati’s engine fans would continue running even after shutting the bike off and removing the key.
