KTM 990 Adventure into the AWD Projekt DT-A | Homemade AWD kit transforms KTM’s 990 Adventure bike

Projekt DT-A is the brainchild of a German engineer, who designed an all-wheel-drive off-roader based on a KTM 990 Adventure. Fitted with a proprietary frame and front swingarm, the prototype adopts a mechanical front transmission system engineered for a no-compromise adventure ride. Guido Koch, a self-employed mechanical engineer from Germany, has enjoyed riding his off-road motorcycles as far off the beaten track as possible for years and, apparently, more than once he found himself pondering how an all-wheel-drive (AWD) kit would have helped him get out of a difficult situation, such as sticking a fully loaded motorcycle knee-deep in the mud in the middle of nowhere. Two-wheel-driven motorcycles have been around for decades, with Rokon's Trail Breaker stemming from the late 1960s as the most famous example. Although this tiny American trail bike has managed to build a myth around its name and is still in production to this day, most motorcycle manufacturers have yet to come up with mass-produced AWD kits. One notable exception would be Christini's mechanical system that has been on offer for several years as an add-on kit for select Honda and KTM off-road models, while recently the American company sells complete AWD motorcycles, and also offers the kit for very special custom builds. Yamaha has also experimented with two-wheel-drive technology, in partnership with Öhlins and its patented hydraulic system. During the early 2000s Yamaha produced a limited number of WR450F 2-Trac production models and even raced some prototypes at the Dakar Rally, while it also toyed with the same principle on the YZF-R1 superbike. KTM relied on a similar hydraulic system during its own experimentation with AWD motorcycles, too, only to come to the conclusion that the added 6 kg (13.2 lb) outweighed any possible benefits. For Guido Koch, all this meant that a factory AWD motorcycle was practically out of the question, especially in the case of big adventurers, like the KTM 990. Challenge accepted. Koch started designing his dream adventurer almost 10 years ago, and in the process he practically built an all-but-brand-new motorcycle himself. The only parts that remain from the original donor bike are the engine, brakes, rear swingarm and rear wheel; everything else has been designed and manufactured by Koch. The Projekt DT-A is set up around a purpose-built trellis frame and a front swingarm in place of the traditional inverted forks of the KTM. Power is transmitted via a belt and chain combo, with a secondary cog feeding the front system directly from the gearbox output shaft. The front setup uses two ball-and-socket joints, one above the wheel that's responsible for steering input and another for driving the wheel. The latter is described as a constant velocity joint, especially designed by Koch for low friction and allowing for a hefty 35-degree steering angle. The AWD kit relies on a free wheel clutch that engages the front transmission only once the rear slips by more than five percent, while it can be deactivated through a lever on the handlebars when not needed. =============== View More ============ Upcoming Bikes in India 2017 and 2018: https://goo.gl/2FkYwi All New Yamaha Motocycles: https://goo.gl/6G9ygd All New Suzuki Motor : https://goo.gl/8NpHHs Honda All New Model 2018: https://goo.gl/Lr1LKt 2018 Kawasaki Model 2018: https://goo.gl/YuUZNv Custom Triumph Motocycles: https://goo.gl/mEMvU6 All New Motocycles in 2017 tokyo motor show: https://goo.gl/KziMNe All New Honda Motocycles at the Tokyo Motor Show: https://goo.gl/v8dMJJ Please subscribe to receive these channels newest video .
