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 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. Please see our Terms and Conditions page for additional information.

    Clutch Cam Set Replacement for my 01' Suzuki TL1000R

    Posted by Brian D. LeClair on Jul 16th 2019

    I've not installed this Billet aluminum Cam Ste one piece replacement MOD but have installed the spring studs into it and when opening the package I found that I was short one of the .036" stud spacers that raise the height of the spring stud. I called the sales dept. left message and was called back by a sales rep. then on the first working day Brock himself called me to clarify what exactly I needed and without question said he would send one to me. I received the one .036" spacer two days later. Brock Preformance takes customer service to the next level they're products are top notch and used throughout the world. This billet aluminum piece is one piece and lighter than me having to weld the OEM Suzuki two piece Cam Ste unit. I expect I will be very pleased once I get it put in, just waiting on new gasket, which I ordered a week before this transaction with Brock. Thank You, B. LeClair

    Must Have!

    Posted by Williamns on Jan 30th 2018

    I can launch much smoother, I have the '15 busa and with the abs, it works great! Bike pulls harder and acceleration is noticeable! Very tasteful mod. 10-15 minutes to install

    This is as important as anything!

    Posted by Gadson on Jan 30th 2018

    I made over 40 passes in one weekend, a lot of them were back to back on a 59-60" gen 2 busa.... And the clutch NEVER CHANGED! Didn't burn it up, didn't warp any steels, no inconsistency whatsoever! This helped me in going over 30 rounds in competition and to win 3 classes in one weekend!! Most people worry about HP only, but this clutch mod is as essential as any thee performance part you can purchase. Gotta have it!!!

    Wish I never waited

    Posted by Young on Jan 30th 2018

    I recently purchased and installed this item. I'm not a avid drag racer but just a weekend/for fun racer. I wish I would have bought this system last year when I bought my b-king. While the clutch is a little harder to pull in, it is worth it. Clutch is smooth and consistent. No more bucking like it states. No more inconsistent clutch grabbing. I have yet to test it out at the track but I can't wait to get there and see what I can do. When I have my girlfriend on the bike, she hardly ever notices my shifts anymore since I'm able to be so smooth with the clutch and there is no bucking/chatter that happens when the clutch fully engages. I highly recommend this to everyone, even the non-drag racers. Get it, you won't be disappointed.
