The Doctor Is In !February 8th, 2011We catch up with Doug Dubach, USGP Vet winner, 17 – time World Vet Champion and creator of DR.D Exhaust systems. DR.Ds Wild Yamaha Dual-Sport !February 8th, 2011The impossible is now routine. Having a real dirt bike with a streetlegal license plate used to be the ultimate fantasy. In some states, it was almost impossible. An underground information network formed to guide riders through the bureaucratic process of legalizing full motocross bikes, but it wasn’t easy.

Motorcycle USA Reviews/DR.D Kawasaki KX450F Off Road Project BikeJanuary 4th, 2011Over the years the Kawasaki KX450F has developed a reputation for not only being one of the most race ready motocross bikes out of the crate but also the MX bike of choice for plus-sized riders. Its robust engine performance, stiffer suspension settings and well proportioned cockpit have made it a very competent motorcycle to ride in a skilled person’s hands. However, a significant portion of riders still prefer to ride on trails off-road as opposed to jump-laden motocross tracks. That’s where Dubach Racing Development comes in. They modified Team Green’s 450 to make it more accommodating for off-road riders in their chosen field of operation. On the exhaust side DRD fitted its top-of-the-line Dr. D Titanium Exhaust System. As opposed to other pipes this one features a spring-less design in which header, mid-pipe and muffler simply plug into each other. Another interesting design note is the employment of metric fasteners instead of rivets on the muffler body which allow the user to easily service it or to remove the USFS Approved Spark Arrestor. DRD’s pipe sounded on par with a freshly packed stocker and top-end engine performance felt strong and didn’t fall off at redline. In spite of it carrying a few extra pounds, set the DRD-modified KX450F into a corner and you’ll be surprised by its low-speed agility. While it does take a little more effort than most other 450 MX’ers, it steers in and out of corners predictably. Part of the reason can be attributed to its lower center of gravity courtesy of the DR. D Radiator Lowering Kit. The kit consists of machined aluminum brackets that physically lower the mounting position of both radiators. A bike that steers so easily might be assumed unstable at speed but the chassis remains composed and feels almost truck-like in its ability to just blast across obstacles with minimal head shake.
