The time has come:we are moving our warehouse. From 10 to 13 November 2026 we cannot ship.
You can keep ordering as usual during this time — the web shop stays open, and from Monday 16 November the parcels will go out again. On those days our service phone is staffed by a skeleton crew only, so we are harder to reach, and we will also be slower in answering your e-mails. Please bear with us — and we look forward to your orders.
Reduce the damaging lateral forces on the valve stem, thus the entire valve train is more stable and considerably less stressed
Larger contact surface at the end of the valve stem compared to the original screws, thus reduced surface pressure and no more pitting
Use even in engines with slightly worn valve ends, as only the intact outer areas are actuated
Extended valve clearance adjustment intervals and therefore very low maintenance
CNC-manufactured, thus highest possible precision and lowest tolerances; each ball is precisely surface-ground, each ball socket is individually checked - thus optimum force closure and even pressure distribution are achieved
Easy self-installation, no adjustments to the rocker arms are necessary
Supplied ready for installation as a set of 2 for intake and exhaust valve including detailed adjustment and installation instructions; suitable for all SR400, SR500, TT500 and XT500
Availability: Currently not available, sorry! New supply expected.
