Pro Shift Kit 

Missed shifts break gears and bend shift forks. Tired of replacing gearboxes every 10 races?

F-Pro Microbearing Detent Arm

Make shifting significantly quicker and virtually eliminate missed shifts.   Makes the shifting relatively perfect. You should not have to pay attention to your shifting. Really!
 (it's what many pro racers use)

Bring your shifting up to high performance  levels.

Reduces shift drum friction for more precise shifting - quicker shifts, virtually eliminates missed shifts.

Takes about an hour to install -  and it's cheap.

feedback  April 20, 2020

Hi Temple,
Some feedback; new shift arm arrived and I installed it (getting pretty
good at putting that spring in now).  With all the silliness going on I
finally got a chance this week to make an extended off road ride.
Probably the same thing you've heard before, very positive and reliable
shifting now; in fact I did not have a missed shift the entire day.
Please pass my thanks to all there, this is a great help to making my
bike even better.
Thanks again,
David, KTM 500, 18

Yes Marc, it's now a very crisp shift.  Before the mod second to third gear shifts was just a hope; never consistent.  I rode a full day last week off road and did not miss a single shift.  Simply amazing now.  Heading out again Friday for another fun filled day.  Thanks again.

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.
