From the originators of Shifting tech!



(stage 2 shifting = star and spring)
EVO Schaltstern Shift Star

Our EVO Shift Star features:
improved material selection to combat arm erosion
improved geometry for fewer missed shifts
stronger, more ductile shift pins
a new German name - Schaltstern

(use with our B10 shift spring)

Improve  BMW gearbox missed upshift and downshift problems. Makes even the stock quickshifter work better.  Use with our B10 shift spring.

Improves shift speed by 3ms to 5ms each shift - up and down - and helps eliminate missed up shifts and more consistent down shifts, especially under trackday and race conditions.
Helps prevent shift engagement dog and shift fork damage caused by missed shifts.
Better shifting - even at race speeds - even with the stock BMW quickshifter.

I know why the s1000rr breaks the pins off of the stock shift star. Marc

Our B10 star addresses the root cause of the pins breaking off the stock star. We addressed missed shifts and stronger pins while they made stronger pins

Easy install - just have to remove clutch basket assembly. No case splitting required. Takes 1-2 hours. Suggest have a BMW Service manual.



Note:
 for smoothest, most effective shifting with  Aftermarket programmable quickshifters:
If using a "switch type" quickshifter shift rod sensor (like Dynojet), with programmable "shift kill duration" delay, you should subtract 5ms to start. 35-40-45ms  is not unrealistic.
"HM" strain gauge type quickshifters - may want to look in to decreasing "sensitivity" a bit as the shift completes quicker with the spring, Changing sensitivity to "less" is similar to decreasing  "shift kill duration".

The Shift mechanism shift spring made the bike shift quicker. The gearbox shift mechanism was pretty lazy. No more missed shifts (I meant fewer missed shifts, more secure shifting and quicker).
