• Visually sight the leading and trailing outer edges of each tire at the same level as the ProAligner™ scale –similar to aiming a rifle.
• From left to right, read and note the 4 numbers where your tire sight-lines intersect the ProAligner™ scale.
• Total the numbers as follows: plus 37, minus 43, minus 72, plus
78. Divide the total by 2.
• The result is zero. The
wheels are exactly aligned.
• Say the wheels above are misaligned, and after totaling and dividing, the result is 3. This means...
• Rear wheel
misalignment equals 3 spaces, or 0.30 inches (7.6 mm).
the rear wheel 3 spaces toward the lower end of the scale to zero the misalignment. Sight again to confirm.
• Look at the ProAligner™ banner above. The scale sightings total 10–31–86+107, which divided by 2, equals zero: The ProAligner™ logo is exactly centered on the webpage.

indicate the crash may have bent or twisted the swingarm, frame or forks
• Turn a rear wheel axle adjusting screw only 1 flat (1/6 turn) and
ProAligner™ will show the change in wheel
• Technically advanced ProAligner™ offers the easiest, quickest, most accurate motorcycle wheel alignment
