Motorcycle manufacturers keep on developing newer and better machines. There is an extensive utilisation of advanced engineering and technologies to make bikes faster, safer and lighter. We’ve seen semi-autonomous prototypes and even a three-wheeled leaning Yamaha. However, there’s still a missing element and that’s an all-wheel-drive motorcycle. Not anymore.
Guido Koch, remember this name because it seems like he’s going to change the conventional motorcycle structure. Koch is a German mechanical engineer and enthusiastic biker. One fine day, he decided to build an all-wheel-drive motorcycle. And today it is a reality. He picked up a KTM 990 as the base bike and started working on it.
Koch calls his prototype the DT-A. It took him almost 10 years to develop this machine. And over the course of time, it was unknown to the world until earlier this year when it was showcased at the IMOT Show in Munich.
To make things work, Koch stripped down the KTM completely. The only original parts of the machine that made it to the final model included the engine, rear wheel, swingarm and brake system. The rest is all new. To provide power to the front wheel, Koch got away with the telescopic forks. A single-sided swingarm was placed there.
Steering is via a trailing arm and auxiliary linkage, and the drive of the front wheel is through a chain that runs parallel to the rocker and is mounted in both swing axles. Power is distributed from the engine via a belt system, which picks up the drive torque using a freewheel directly on the pinion. The catch here is that the engine will deliver the power to the front wheel only when the rear wheel reports a wheel slip of more than 5%. Also, you can control whether you want power in the front wheel or not by a simple toggle of a switch.
Koch is extremely confident of his work. He has patented his two-wheel drive system. He has got all the engineering drawings and tools that he used to build up this beautiful machine, and he says that it can be replicated to fit other motorcycles as well. It is an astonishing project. We hope that some motorcycle manufacturer would take notice of this. I mean, would we be really riding all-wheel-drive motorcycles in the future? Anything can happen!
