If you’ve been lucky enough to access the pit lanes during top-tier races, the likes of Formula One and MotoGP, chances are high that you’ve seen racers pootling around in scooters. A lot of them, including Michael Schumacher, Lewis Hamilton and Jenson Button, are hardcore motorcycle enthusiasts, and have some stunning examples, both stock and custom, stashed in their garages. Which brings us on to Marcus Walz, a familiar name whose builds we have featured before, the Walz Hardcore Hammer and the WCR900. With a clientele that includes Sebastian Vettel, Kimi Räikkönen and David Coulthard amongst others, Marcus is no stranger to top-shelf customs and, with this year being the twentieth anniversary of Formula One legend Ayrton Senna’s (another avid motorcycle fan) passing at Imola, the German builder has just crafted a stunning limited edition Moto Guzzi Le Mans in his honour.

Based on 1970s Moto Guzzis from the Le Mans Mark I series, the Ayrton Senna Tribute Bikes are completely rebuilt from the ground up, with custom bodywork finished in colours inspired by Senna’s famous helmet designs, taken from the Brazilian flag and painted by Sid Mosca. The 850cc engine has been bored out to 1040cc, so that it now makes 90hp, while weight has been pared down to around 175 kilos.

The complete bodywork, including the fuel tank, seat section, headlight fairing and front fender is handmade from 1.5mm aluminium sheet metal. The sandblasted and powdercoated frame is joined by an upgraded suspension with new fork tubes, internals, and progressive springs, while at the back you can find YSS Z-Series shocks with adjustable preload, rebound and length. The original 18″ Le Mans cast wheels are black powdercoated and shod with Avon Roadrider tyres sized 110/80 at the front and and 130/80 at the back. Braking is taken care of by Brembo two-piston calipers at both ends, clamping on drilled stainless steel rotors. LSL clip-on bars and hand-fabricated, fully adjustable rearsets complete the picture.

Only three have been made, with the second and third examples going to customers in Brazil and Switzerland. The first bike is still owned by WalzWerk Racing to display on events and exhibitions around the world.
