Ayrton Senna da Silva, perhaps the most talented Formula One driver of all time, was also a keen motorcyclist. This year in the twentieth anniversary of Senna’s passing German builder Marcus Walz has made a stunning limited edition Moto Guzzi Le Mans in Senna’s honor. Marcus is a familiar face in the Formula 1: his customers include Sebastian Vettel, Kimi Räikkönen, David Coulthard and Gerhard Berger. As you can imagine, his work is very much in the premier league. Walz has punched the 850cc engine out to 1040cc, and it now delivers an easy 90hp; weight has dropped to around 175kg (385 lbs). The custom sheet metal is 1.5-millimeter aluminum, including the custom gas tank, seat section and front fender. Brembo two-piston calipers are on braking duty at both ends, now clamping on drilled stainless steel rotors. The rearsets are hand-fabricated and fully adjustable, and the clip-on bars are from high-end German specialist LSL.
