SDI Spring Perch Set - YZ250F/450F SDETCV24-MX-SET

If your YZ250F or YZ450F is bottoming out on bigger hits or washing out through rough terrain, a properly tuned spring perch directly impacts how your suspension responds under load. This set lets you dial in the perfect balance between initial support and deep-stroke compliance—critical for maintaining control and comfort across multiple riding disciplines. Whether you're racing SX, charging MX, throwing down FMX tricks, or grinding enduro miles, having adjustable geometry means one bike can work for all of it.

The SDI Spring Perch Set eliminates the guesswork with a straightforward modification guide and U.S.-manufactured precision. You'll feel immediate improvements in bottoming resistance and mid-to-deep stroke performance on demanding terrain where stock geometry falls short.
