Brock’s Hayabusa Gen3 Clutch Conversion Kit Stands out at XDA

Hayabusa Gen3 Clutch Conversion Kit

Brock’s Performance recently released our new Suzuki Hayabusa Gen3 Clutch Conversion Kit with Ultra Mod to the masses. This past weekend Patrick Cooper entered his Hayabusa in the XDA Super Stock class to test how it measured up to the competition. Right off the hit, the bike launched smoother with a 9.159 at 157.82 off the trailer. His second pass improved to 9.041 at 157.26 mph to set him up in the middle of the qualifying field.

Once eliminations started, the bike’s performance kept rolling out the numbers, with the best ET of the weekend at 8.907 at 158.71 mph. “This is the quickest and fastest pass ever for an XDA Legal Super Stock Suzuki Hayabusa Gen3 motorcycle. The event was shortened due to weather, so I couldn’t make many passes, ” stated Cooper. “But I can’t wait to get back out on the track to see what she can really do; there is more horsepower in there!”

Clutch Conversion Kit w/ Ultra Mod for Suzuki Hayabusa (22-23)

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.

  • Converts the OEM ‘ramp-style’ assist/slipper clutch into a traditional style multi-plate clutch design
  • Utilizes Brock’s Performance Ultra-Light Billet Clutch Mod Kit (included), which eliminates the OEM back-torque limiter
  • Required for smooth clutch control when attempting to launch the Hayabusa (22-23) from a dead stop
  • Conversion eliminates ‘bucking’, grab, chatter etc… during drag-style launches (video)
  • Complete drop in replacement; no modifications required
  • Designed for use in (22-23) Hayabusa models only

In the final, Whiting faced previous class champion Mark Hylton, and it would take everything he had to get around him for a win. When the bulbs flashed both riders rocketed out of the gate. Both riders fought wheelies at the 60′ mark, but Courtlan recovered quicker, allowing him to keep his forward momentum and stay ahead of Hylton to the finish line. This was Whiting’s first DME Racing Real Street win.
