Most motorcycle forks float on at least one side of the axle. This means that the fork is not held in a specific position along the axle, and is fixed in place by pinch bolts on the fork itself. As any professional mechanic knows, making sure a motorcycle fork is properly parallel when installing a wheel is an important task, as a fork that is pulled in or pushed out by the axle will feel harsh, negatively affect suspension action, and even prematurely wear bushings and seals. Previously, mechanics would compress and release the fork several times with the pinch bolts loose, or spin the wheel and slam on the front brake to shock the fork mount into parallel. However, neither of these methods assures the fork is parallel, and before now, there was no way to really verify that they were.
Motion Pro developed a simple but ingenious way to align the forks on off-road and MX motorcycles. With the ForkTru™ (part# 08-0412), you will always know your fork legs are perfectly parallel from top to bottom. Proper fork alignment reduces stiction which allows the suspension to work freely, leading to better handling and increasing the life of your fork seals and bushings.
The tool is simple to use, you set the ForkTru™ to the width of the upper fork tubes below the triple clamp, and then move it to the bottom fork tubes where you can precisely adjust your fork width to match the top. The age old method of pushing your forks up and down will only leave you guessing if they're aligned properly, but the ForkTru™ will give you the accurate results you're looking for with no measuring needed.
The Motion Pro ForkTru™ Fork Alignment Tool will work on 27mm to 62mm diameter fork legs that are 140mm to 220mm on center. Made of anodized 6061 aluminum with a Motion Pro laser engraved logo, it is durable and lightweight, and features knurled adjustment screws for easy setup.
Any time you remove and replace your front wheel you need this tool, this is a must have in your toolbox if proper front suspension setup is important to you. The ForkTru™ is available through your local dealer.
