EVO-7 Shift STAR Kit


Includes Factory's AWESOME Shift STAR  - Totally changes the rough shifting the Kaw 6's are known for into the sweetest shifting Kaw - The one you've always wanted!
Includes: Factory Pro designed, refined and manufactured DETENT STAR, Factory Pro Microbearing Detent Arm, heavy duty detent spring and gasket. Makes shifting quicker and more positive - "virtually" eliminating those nasty missed shifts. The stronger detent spring rotates the shift drum quicker, so the gears are more likely to engage under quick shift conditions - and "lazy" ones, too -
The Factory Pro Microbearing removes friction for the quickest shifting.
The closest to a "paddle shifter" for a motorcycle that you will ever find!!

******************

Positive feedback rating    Oh, the shift star works great.  I mean the Kawis have always been a bear to shift.  And the EVO cleared that up.  Love it -
Thanks -  Douglas  Isham  …


Hi Marc,
Just wanted to let you know that your EVO-7 Shift Star Kit ROCKS!  I've been having problems getting a lot of missed shifts between 3 & 4th gears in my 636 and after installing your kit, the problem is 100% GONE.  I raced out at Streets of Willow this past weekend and didn't have one single missed shift anywhere and the positive engagement feel is perfect.
Thanks for making my 636 an even better bike!

Billet Engine Cover

RH Billet Engine Cover with SKIDzz.
Absolutely the strongest cover you can buy - and has the highest strength / weight ratio available! Exclusive, patented Steel SKIDzz replaceable insert takes the damage!
Hi-Tech flycut surfaces can be polished to a brilliant sheen for the ultimate in show! Does not require a new gasket.
The stock cover grinds through more easily than the Factory Pro cover when "low sided" on the right side of the bike.  If the stock cover breaks, the bike settles even lower and the radiator becomes even more vulnerable to damage.
