SHFT-PRO-KT75-KT-CER
$100 to $139.95
F-Pro Pro Shift Kit

The stock shift spring wears out, gets soft and ends up delivering poor action, indistinct shifts and occasional unexpected false neutrals. The stock detent arm needs upgrading. The flaccid shifting 690 syndrome.

Virtually eliminate missed shifts and false neutrals.

This bike has kind of lazy shift action. Not what you want when Super Motard racing or jumping those doubles or splitting that lane.

Low and midrange Billet Velocity Stacks

Patented Quick change, high velocity design.
Super seal design keeps all the pressurized air IN the airbox.

Note from Marc:
The "Midrange" Race stacks are my choice for any street and most track use.

The additional 4-5 HP across the 7000 to 9000 rpm range augments the 2 True HP gain at 10,000 rpm.

MIDRANGE
