Not all wheels for a motorcycle can be re-engineered to meet safety specifications once they have been damaged by potholes and scrapes against curbs and road debris. When extreme damage occurs it is probably better for riders to buy another tire rather than risk death or injury. A motorcycle wheel repair process requires a different machining tool than the mounted machine process that is used on wheels for automobiles.
Repairs are possible but will rely on how the technician determines what type of damage was done. Most motorcyclists would prefer to restore a tire assembly to its original condition. The lowest estimate an experienced technician could give would be to restore the base metals to 95 percent of original condition.
Speed tests will need to be done to test how wheels turn in a riding environment. Motorcycle wheels spin at incredible speeds that require a precision balance. If that balance is out of alignment, then it will spin sufficiently but prove unsafe at some point down the road. All areas that contain an alloy will need to be inspected before it is remounted on the bike for another high performance run.
Those spins will place a lot of stress on the metal base but can be repaired if certain standards of repair are met. The axial assembly will need to be inspected for cracks and if any are found, then the technician will have to perform some welding. Using hydraulic pressure, a technician can mount the tire in a simulator and apply enough pressure to disclose invisible cracking that has occurred in the alloy centering.
Well equipped shops will have hydraulic pressure machines that the device is mounted to for the purpose of testing for cracking. Repairs which are completed during this process to correct minor cracks in the alloy parts.
A technician will need time to conduct these tests and others. A visual inspection might provide some of the answers he is searching for, such as damaged wheels that have loosen spokes, or bent framing. Slight bends deserve further consideration and the technician will make checks for lateral and radial run-out.
Then the technician will complete a vertical damage check to rule on radial soundness by using metric measurements and spinning techniques to determine how much the tire is out of round. From this point, hydraulic pressure will be applied to correct each discrepancy and determine what kind of motorcycle wheel repair will be necessary.
