I make a prototype microbearing Detent Arm for the crf1000L and we can't find a SINGLE mechanically motivated rider who is annoyed  by the manual  shift model's kinda lazy shift action and occasional ghost neutrals in the upper gears and the occasional jumping out of 2nd gear if the rider isn't paying attention.

RC-51 Feedback

Hello,I wanted to email and thank you for a great product. I have an 2002 Honda RC51 and have done every mod in the book and I recently

ordered one of your shift star kits. I am totally impressed and v ery pleased with the dramatic improvement I noticed in shifting.
Out of all my mods this is in the top 5. 1 being Ohlins forks. 2 being an Ohlins rear shock. 3 being a slipper clutch. 4 being a Scotts steering
damper and ...... 5 being the EVO SHIFT Star.
Thank you for researching and designing such a great improvement that only us motor heads understand what performance should be!!!!!!
Only thing that I would say ( and not a negative at all) is that installation was not as simple as I expected from reading. But, that's no biggie!!!
I have a killer set of tools and super sweet shop so the project was flawless. It just took 5 hours start to finish. But, again, we all know it
takes time to do things right.
Sincerely,     Brian McCormick ------FLYIN BRIAN

Thank you very much fellas. I ot one of your kits last year + ive only just ridden the bike after winter rebuild. What a difference, gear change is super quick + precise. Feels like a different bike. Considering a stronger spring is fitted, to me it feels much lighter, the action is so slick. I'm over the moon.  Bike is rc51+ I'd recommend this mod 100%. Best wishes + regards, Gary Waller  [UK]

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.
