Walt Siegl SBK #1 - January 2019 Window Bike

Walt Siegl Motorcycles Superbike

We have been lucky enough to have had some very nice, very rare, and very desirable motorcycles grace our front window. But, this one might take the cake. What we have is the culmination of three years of passion, ingenuity, and straight-up hard work. The Walt Siegl Superbike is the full-fared carbon beast that is starting off the Window Bikes for 2019.

The frame is aircraft grade steel, built as a perimeter frame with World Superbike geometry. The tricky part about the frame design, is that Walt wanted it to fit both air-cooled 2-valve and liquid-cooled 4-valve Ducati motors. 
 

The engine, built by the legendary Bruce Meyers. “It’s a hybrid,” says Walt. “The engine has an air-cooled top end with redesigned, CNC-machined combustion chambers. Plus oversized titanium valves, race cams, and short-sleeve Mahle pistons on top of titanium rods. The bottom end is from a 4-valve 1098, balanced and lightened with a polished, stainless crank. The exhaust headers are custom-made from stainless steel, and terminate with a pair of very sleek titanium mufflers from Arrow.

The suspension is on the cutting edge of what is available today. Öhlins have been selected to handle both the front and rear components. The front forks are FGR World Superbike-spec, and a TTX rear shock was built to Walt’s own specs. The machining and finish on the front forks is something that has to been seen to be appreciated. 

The bodywork, weighing just 9 pounds, is made entirely of pre-preg carbon fibre. The rear subframe/tail/seat is carbon fibre as well, and crushes the scales at just 1.8 pounds. The entire bike weighs an astounding 340 pounds (155 kilos). To give you a frame of reference, that is lighter than Ducati’s current MotoGP bike. 

Walt and his team have even gone through the trouble of designing a race style wiring harness and reprogramming the Ducati ECU. The bike features all the electronic aids you would expect, like traction control, track data acquisition, and clutchless quickshifting, which all allow the bike to be safely enjoyed on the street and unleashed on the track. 

There is way more to this bike than we could possibly convey in this small post. The level of craftsmanship and execution are what you would expect from a factory team, but was executed by a niche motorcycle builder in New Hampshire. The bike is the brain child of Walt Siegl, but he is quick to point out, that without the expertise of his dedicated team, the project would never have happened. Give these guys some credit and come by this month and see it for yourself!
