Gray Area KTM Promo Codes 2025: Up to 20% OFF Auto-Apply

Titanium valve spring retainers for the 390 series of motors are available from Gray Area KTM. You will require them if you operate your 390 at high RPMs for an extended period of time. The factory valve spring retainers will expand under these circumstances and obliterate your cams. These also use the far more typical and widely accessible 9.48mm valve shim. In addition, Gray Area KTM have the 390 Performance Valve Kit, which replaces the factory KTM valves with a stronger valve. These are drop-in replacements that have the exact same dimensions as the factory 390 valve. The factory KTM exhaust valves are composed of common steel and have a friction weld in the middle to make them easier to produce inexpensively. Extreme accuracy is used in the manufacture of these valves in Germany to ensure maximum endurance and horsepower.
