Chimera Builder center shock engine bracket for Yamaha Zuma 125 engines is a bolt on application to the engine. However welding the shock tabs will be required to better accommodate those who would like to run fatty or non-fatty rear wheel set up. Removing the shock bushing from the engine is necessary. A aluminum bushing is included to replace the bushing. The center shock bracket is made from DOM tubing and is left raw so that you can coat it however you like!
