Let's face it, the 690 and 701 are great bikes, but the transmissions shift like garbage. The idea is that when you nudge the shifter it should actually go into the next gear. False neutrals in the upper gears and a generally notchy feel to them does't exactly inspire confidence either.

I've been wanting one of these for a while and finally pulled the trigger to install during my spring bike maintenance (riding season is finally here in Alaska).
End result I'm totally blown away how much better my 690 shifts now. I can no longer get false neutrals going from 5th to 6th at highway speeds even trying to by barely shifting. Wish I had bought this a long time ago. All the shifts feel really solid on top of the false neutral problem being gone.
The instructions factory pro have on their website aren't very good, but there's a helpful video of another rider doing this install on Youtube that makes it super simple.
If you're on the fence for this upgrade, do it. Definitely worth the cash.
