Good Luck Suzukipride, when racing areanacross there is only 1 pipe choice,that pipe is a BILLS pipe. Give Bill a call he might have some arenacross stuff sitting around. The Suzuki team used a shelf pipe, the same 1 available to the public, all the years they raced 125 and 250 pro classes, good stuff. I,m racing friday night supercross next year, it,s a outdoor track.
