For over 25 years, Trac Dynamics has been setting the world wide standard in custom swingarm manufacturing. Here at Trac we build more aftermarket swingarms than anyone on the planet, and for for three good reasons: Quality, Performance, Value. Our quality begins in the manufacturing process. All arms are made "in house" at our facility using our exclusive bridged extruded aluminum alloy material along with precision cnc machined billet components. These parts are then hand fit and assembled using the most technically advanced welding system available today. The performance of our products are legendary, since the mid 80's racers around the world have trusted the name "Trac Dynamics" to give them the advantage they need to perform at the top level of their sport. Our value speaks for itself, when you make an investment in the customizing of your motorcycle, rest assured you are getting the most for your money. Here at Trac our Swingarms are built to stand the test of time, and your satisfaction is always guaranteed!

Yamaha swingarms for STOCK WHEELS are made to use the stock brake caliper for that year and model. 240 versions are made with a universal mounting tab installed, and must use an aftermarket universal brake kit.
