for the NC23

Adding the EVO Shift STAR kit makes shifting so sweet that you'll want to ride just so you can slip the bike into each gear with silky precision. The Marc Salvisberg designed Shift STAR has optimized compound arcs, peak heights and valley depths that almost do the impossible - it's easier to get out of gear and shifts quicker into the next gear -
The normal, original lag in shift completion rate is what makes the transmission feel "clunky" around town.

Make shifting MUCH quicker and virtually eliminate missed shifts. Helps address missed shifts caused by poor shift detent "star" profile.

The kit includes the new Factory Pro Shift STAR and the Factory Pro detent arm and spring, as described below.

Northern California's most unforgettable flying experience.  No experience required.  Open weekends!

The extension of the laboratory for engines of the Swiss Federal Institute of Technology was completed in about 1935. Its architect was Rudolf Otto Salvisberg (1882-1940). He had a successful career in Berlin but returned to Switzerland after the advent of the Nazis. His architectural style was somewhat similar to that of Erich Mendelsohn. The staircase of the laboratory is in normal use but well preserved.
