WARNING: 05 Beta 525 Intermediate Gear Failure!

Attention '05 Beta 525 Owners! Your Beta is at risk of an intermediate gear failure. There is a known design flaw in the '05 and earlier KTM 525 RFS motors related to excessive back torque that causes the intermediate gear to fail. Often this failure will just result in an inability to start the bike with the e-start, but gear debris in the motor may cause other damage. The '06 RFS motors solve this problem with a back-torque limiting gear - see the '05 Gear Fix page for details on this upgrade. needs you!
