Yamaha XS 650 or Yamaha SR 500 - Extraordinary Quality Swing Arms For Yamaha single and Twin - They can be used on TT or 1/2 mile track bikes. Main tubes are 1" x 2" .065 U.S.A c.r.e.w steel. Tubes are miter cut, then axle slot (.875 x 1.350) and notches are put in with a CNC mill. All parts are put in a precision fixture and carefully tig welded. Crosstube is bent from 1 1/2" x .065 round, which has a greater strength than a straight tube. Nicely formed shock mounts with 5/16" holes. Setup for a floating brake and quick change tire rotation. Each swing arm is prestressed for extra strength. Fits nicely into your stock or after market frame. Using stock pivot bolt and spacers. D.O.M. U.S.A tube that holds bronze bushings is line bored and reamed 1.125 for exact fit. Two length sizes 18" or 19" center to center. Ready to ship - priced to sell $150.00 plus shipping - (this is below cost) while supplies last. We originally manufactured these for a company called Shell Racing. He never paid for them, we have had them sitting and now it's time to get them out. He was buying them for $190.00 each we giving a discount just to re-group a little of our money. They were made for stock motorcycles. We don't have all the extra parts for them. If you have a little talent or your buddy does you can make them work with no problems. We have sold quite a few so far and have never heard anything bad. Excellent quality. I am in the process of seeing if I can find any pictures now to show what it looks like on a bike, but no guarantee I can find any. Hope this info and the other info helps everyone out.
