As of 2016, TDR has returned to the Road Racing scene. With 4 riders running the complete AHRMA series of 10 races and a selection of WERA races as well, it should be an interesting & exciting season. We are concentrating on Vintage racing at its best. TDR is proud to be a Class Sponsor at AHRMA events throughout the year. We have concentrated our efforts on 2 different classes for now. The Super Moto / Sound of Singles and Open 2 Stroke. This allows us to develop complete engine packages for the RZ market and new products for the YZ250 market as well. We currently have tested and proven engine packages for the RZ in the following sizes. 392cc, 421cc, 443cc, 465cc. Larger ones to come later. These packages include carbs, intake manifolds, reeds, exhaust, silencers, CDI systems, rear sets, and much more
