  • THIS IS A SET  Brock's Clutch Cushion Kit+Ultra-Light Billet Clutch  for your Hayabusa 08-19 /B-King 08-11
  • Sku:270136+ Sku:270461
------------------------------------------------------------------------------------------
Sku:270136 Brock's Clutch Cushion Kit:
  • Mounts on inner hub before clutch pack is installed
  • Floating action promotes chatter-free operation during dead stop launches
  • Quicker ET’s for serious sportbike drag racing
  • Smoothest operation, especially with modified engines/chassis
  • Heavy duty spring kit included for longest clutch life and highest MPH
  • Up to 25% more lever pressure for drag and high speed racing
  • Clutch Mod #270461 is required for use with this product-INCLUDED
  • DO NOT use ultra mod spacers with cushion
  • Billet 6-position adjustable lever cam included
  • MTC Conversion Kit #270435 required for use with a MTC Billet Inner Hub

With the Clutch Cushion Kit, the clutch actuation is COMPLETELY chatter-free. There is no longer a need to oil your clutch plates before heading to the track with the hopes of getting a couple of smooth passes in before they start acting up. This feature alone saves the stock Busa owner a considerable amount of work, time, and hassle. Another feature is noticeably increased clutch life due to the addition of Brock's Performance engineered clutch springs designed specifically for this application.

In big-displacement/high torque applications, the results are multiplied even greater. The modified-engine Busa owner has been frustrated in the past due to the unpredictable action of the clutch when additional power is applied. Billet-this-and-that help some, but they are only band aid cures. The problem is in the clutch design, it is a mechanical problem. The Brock's Hayabusa Clutch Cushion Kit is a mechanical cure.

The kit includes:

  • 1 - Dual-stage clutch cushion
  • 1 - Cushion ring
  • 1 - Thick fiber clutch plate
  • 6 - Load control clutch springs (a staggered assembly of four heavy duty springs and two extra heavy duty springs, no spacers are required)
  • 6 - Clutch spring studs
  • 6 - Clutch spring bolts with washers
  • 1 - Clutch cushion kit assembly instructions
  • 1 - 6-position clutch lever cam
  • 1 - Spare detent ball for the lever cam spring
  • 1 - Lever cam assembly instructions

Sku:270461 Brock's Ultra-Light Billet Clutch
  • Eliminates ‘bucking’ during dead stop launches
  • Helps protect chain and drive train components from damage
  • Smoother operation, longer clutch life, lower ETs
  • Replaces factory back-torque limiter
  • Billet 7075 aluminum, mil spec. hard coat construction
  • 60% lighter than stock for quicker engine acceleration
  • Lever pressure increased only 10%
  • Includes clutch spring shim spacers
  • No core charge or exchange required

When it comes to enhancing the overall performance and drive train safety of the Suzuki Hayabusa, the most popular and affordable upgrade is the Ultra-Light Billet Clutch Mod. This mod replaces the factory installed back-torque-limiting clutch assembly (sometimes also known as a ‘slipper clutch,’) allowing the rider to perform a smoother, more controlled dead-stop launch, as opposed to the grab-n-jerk motion associated with trying to launch the stock machine. As an additional benefit, the Ultra-Light Billet Clutch Mod helps reduce component wear associated with quick starts, regardless of the surface. ‘Slipper clutch’ equipped bikes can experience abnormal wear leading to frequent adjustments, broken drive chains, premature damage to sprockets, worn out/broken outer clutch baskets, and even bent output shafts, all of which can be attributed to the violent jerking motion encountered from the factory clutch arrangement.

If every hundredth of a second and smallest detail counts in your world, the Ultra-Light Billet Clutch Mod is for you. Thoroughly tested in some of the highest power bikes in the world, this mod also attacks the rotating mass equation in the Hayabusa clutch area. The energy transferred from rotating the weight of the steel OEM components can now be used to push the bike forward – quicker! The Ultra-Light Billet Clutch Mod weighs in at a feathery 139 grams, compared to stock at 340 grams.

Kit includes shim spacers for use with the stock springs, for a slight increase in clutch pressure. Not only will this help the bike launch quicker without creating drag strip chatter, but it will also help increase top end speed.

To further optimize the experience, we suggest the Clutch Cushion Kit  (INCLUDED) be used in combination with the Ultra-Light Billet Clutch Mod for an unbeatable performance upgrade.(

Attention: Although casual riding is generally unaffected after the installation of this product, some rear wheel ‘chirp, hop or chatter’ may be noticed, depending upon rider habits. All Brock’s Performance products are designed for Competition Use Only.
