Testing & TUV Approval
Each Performance Machine Wheel and Brake is designed and engineered to specific standards and thoroughly tested. Starting with computer simulated stress analysis, PM engineers assess each design. They do not stop there, though, as they quantify their findings with data from physical testing in their sophisticated in-house test department. PM tests to strict world wide standards such as JASO and TUV.

Cornering Test
Performance Machine's physical testing begins with a cornering test where they reproduce the incredible stress created during cornering on a motorcycle. Each wheel design is subjected to this mechanical torture and then evaluated for damage. The wheel is tested at 2.25 times the maximum tyre load for 1,000,000 cycles. If a wheel does not survive this test or any other test, it is scrapped and redesigned.
Radial Load Test
Next, the wheel is loaded on to a giant Radial Load Tester which simulates a load on a tyre/wheel assembly in a vertical riding condition at 2.25 times the maximum tyre load for 100,000 cycles on a front wheel and 500,000 on a rear wheel. The wheel is spun up to speed during these cycles then checked for flaws before enduring the next physical test.
Torsional Load Test
The third test in the PM repertoire is the Torsion Load Tester which simulates what a wheel would endure if you were shifting at wide open throttle or hitting the brakes to the point of skidding for 100,000 cycles with the heaviest and most powerful production bike. Load sensitive rams cycle back and forth replicating real world style torture in an attempt to rip the hub out of the rim. Each wheel design is given this torture treatment before moving on to the final physical test.
Impact Test
The fourth physical test sends each PM wheel design to a massive Impact Testing unit which simulates the pot holes and road hazards that a wheel is subjected to in the real world. Each wheel design is wrapped with a tyre and a hard edged hit is replicated; the wheel must retain air pressure for a specified amount of time in order to pass. If a wheel passes this final test it lives to see another day and moves into production.
Brake Test
Stock V-Twin motorcycles are coming out of the factory with more horsepower on tap than ever, rarely does it stay that way, though and the bulk of these bikes are upgraded with high performance pipes, cams, and carbs and other go fast parts. In an effort to increase performance riders overlook the very system designed to bring it to a stop. In-house dyno testing ensures that PM calipers maintain proper pressure, do not flex, provide superior stopping power, and all functioning parts hold up to daily use to bring your motorcycle to a stop in a safe distance.
