The concept began with Timmer’s rumination over the skeletal visage of a frame, a pair of wheels, and a set of forks that sat languishing in a shed. The builder’s vision was that of a seamless and unique café bike built around a Ducati 900ie engine. Once the rebuilt Italian L-twin power-plant was fitted into the specially adjusted frame, the real artistry began. A foam core for the clay model of the seat and bodywork was crafted and fitted to the rolling chassis. In keeping with Timmer’s vision of a seamless café racer, the entire tank, seat, and tailpiece were designed and sculpted in unison on this clay model.
In a process that Timmer’s beloved grandfather could not have imagined, the final clay model design was translated into rough 3D CAD data, making use of a 3D scanner. This data served as the starting point for the 4Nol’s digitally perfected one-piece body. When this stage was complete, fiberglass molds were made and the final bodywork was laminated. The end result of this tactile and digital effort was exactly the unified and seamless silhouette that Timmer craved. Smokin’ Motorcycles now offers this body as a kit for Ducati Monsters.
On the exhaust end, Smokin’ Motorcycles developed a new 2-1-2 exhaust manifold system that leads to the two Spark megaphone silencers. Both silencers are mounted with beautiful CNC milled brackets, which were engineered in house at Smokin’ Motorcycles. The exhaust cans sit at an aggressively rakish angle, and the sound emanating from them is equally aggressive.
No stylistic or performance stone was left unturned on the 4Nol. The frame, swing arm, and wheels share the same satin black powder coating, and the bodywork is painted a beautiful metallic grey. A carbon fiber front fender is fitted, and clip-on bars are mounted to a visually striking upper triple tree. On the bottom end, fully adjustable foot pegs are mounted to the custom frame. The engine is accented with details such as aftermarket aluminum timing belt covers, clutch cover, and a gold colored pressure plate.
The entire package achieves exactly what gleamed in Timmer’s eye when he looked at that basket case in the shed. The 4Nol is an excitingly eclectic mix of influences. It was created by Dutch visionaries, beats with an Italian heart, and serves as a fitting tribute to a grandfather’s legacy. That’s a bike with character and purpose.
