Today I happened to see a two-stroke pipe made nearly 20 years ago for the Yamaha SuperJet by R&D. After so many world and national titles previously won by using this pipe on Yamahas. Riders like Nicolas Rius, Victor Sheldon, Chris Fischeti used it on a Polaris and Alberto Monti. I was so surprised when I found out that Theo Beaumer and Joulie Baulteau won three World Titles last week by using exactly the same two-stroke pipe.
