Its active adoption of computer-aided design and aluminum materials significantly improved durability, dispelling the image of being \"heavy, slow, and prone to breaking.\" In contrast to the successor Twin Cam, which became too smooth, the Evo is still highly popular for its raw V-twin throb and pleasant three-beat sound.
