The Man & the Machines KTM Scrambler is a reminiscence of the grand 1960s and 70s motocross era. An elevated stance and dynamic proportion are paired with countless design clues and technical features which tell the story of vintage motocross.

Being based on a 2005 KTM LC4 640 Supermoto, power output, suspension and reliability are solid and electrics simple. Many hand built parts are combined with state of the art 3D printed and laser cut components. A simple and bold tank graphic incorporating a hand drawn interpretation of the KTM logo gives the garage build a strong personal touch and creates just the right balance between vintage and modernity.
It was April 2016, first closely studying vintage motocross bikes and scramblers, then meticulously researching the most suitable donor motorcycle. My transport designer brain managed to build every detail of a custom scrambler in front of my eyes, creating an unwritten build manual for my Photoshop dream. The dream of a vintage inspired bike yet modern, using hand craftsmanship on the one hand and state of the art manufacturing technology on the other.
Eventually the perfect donor rolled into the workshop. Punchy single cylinder engine, fully adjustable suspension, spoked wheels and simple electrics. Stripping the Supermoto was done in thirty minutes. In the correct order of Proportion-Surface-Detail, first the tank from a Honda XL250R got a gentle tunnel hammering to fit over the chunky frame.
This resulted in having to reposition the coolers further down since the original tank sits a lot further back and allows for the coolers to sit quite high. The square profile sub-frame went straight in the bin and was replaced by a custom 1“ round steel sub-frame incorporating the original air box.
The exhaust headers are modified KTM Duke 2 parts. Not being a fan of empty triangles under the seat, I designed side fairings to fill that space and to cover the air box at the same time. A steel rear and aluminium front fender were bought and modified. To enhance the vintage look, the fat 17“ spoked rims did not see any powder coat but got a polish instead and were fitted with meaty Continental TKC 80 rubber.
Up front a 5 ¾“ clear glass headlight shows where you’re going and at the rear a simple LED tail light is tucked in between fender and number plate. Black little Motogadget M Blaze Pin indicators are neatly integrated in the hand made cooler protector plates and the sub frame.
Having finished all handmade fabrication it was time to go hi-tech and have the bike fully 3D scanned in order to build a digital model of the side fairings and the front lamp cover. Having defined all mounting points prior to the scan, the fairings could be built to match them perfectly and were eventually 3D printed from PA12.
