The McIntosh Pro-Arm set the standard in 1984 for today’s single shock sport bikes. As Sportbikes have changed design by producing higher horsepower, we have also redesigned the Pro-Arm to meet the higher horsepower demands. This is the swingarm used on Walter Sprout’s record setting (206mph) Pro-Street Hayabusa. Constructed from 4130 chromoly and TIG welded to aircraft standards.
Any swingarm 12″ over or more, we suggest adding a chain roller to eliminate chain sag.
