When we do bike road tests, there are several things that we look for and comment on, among them: styling, comfort, horsepower, handling and braking Vet the majority of tech articles that appear In this and other magazines center around either improving a bike's styling or adding horsepower to its motor. Well, a you build a faster bike, you better look into making it stop equally well. But, better brakes can also add to a bike's visual image. To that end we have decided to equip our hopped up 2006 Dean Street Bob with a set of polished floating rotors and Z Plus bake pads, from Lyndall Racing Brakes, (LRB). These benders are not only a match for the bikes hot motor and revamped suspension, but they well also improve its looks.

The LRB rotors are a piece of mechanical engineering. They are fabricated iron heat treated 420 stainless steel The rotors' pad contact area is super smooth and dead flat for better pad/rotor gap.

For silent operation, the outer rotor is attached to the corner hub with 10 spring-loaded trunnions. The careers “star" pattern blends well with either wire wheels or Harley's cast aluminum wheels. The LRB floating rotors fit all 2000 up Harley’s except for 2006 Land models that are tit too with 10 spoke cast wheels.

The LRB Z Plus brake pads use a combination carbon/Kevlar friction material. The Z-Plus pads have been designed to give good stopping power and run clean while being quiet There are LRB Z Plus pads avail for most Harley, from 1973 to present.

Our new brakes worked well, they were super quiet and had excellent stopping power along with hot looks. Lyndall Racing Brakes are available through your Drag Specialties dealer.

I installed a set of Lyndall brake pads on the Road King last year and was so pleased with the results that when the company announced the release of their new fully floating polished rotors, 1 was first in line to grab a set. First I threw one on the back of the bagger (along with a fresh set of Lyndall's Z+ pads) just before taking off for that big party they hold at Daytona Beach every March. I didn't install the ones on the front for the ride over to Florida since 7 was unfamiliar with floating rotors, and being the conservative mechanic that I am (i.e. paranoid), didn't want to be in the middle of a trip and have all three brakes screw up on me. But the rear disc performed flawlessly during my 2,300 mile ride and I couldn't wait to see the difference when I slapped the twin rotors on the nose of the Road King. But I was not prepared for the huge increase in braking power.

Lyndall starts with a 420 stainless blank, which is then heat-treated to Rockwell C-37 harness. After machining, the rotor is blanchard ground and left 1mm thicker than stock. It then goes through a chemical passivation process that removes surface oxidation in a parallel. This step aids in the final polishing and allows for the product's mirror finish. It is then assembled using 304 stainless wave springs. If all that sounds pretty high tech, consider the fact that Lyndall enlisted the design services of C&D Aerospace to spec the materials and processes. This hired gun even went so far as to designate the end mill to use for manufacturing along with motor speeds and feed rates (so I guess this actually does qualify as rocket science). These are not cookie-cutter units being punched out in mass quantities. The current production rate is two per hour. Even the venting holes are drilled at a precise angle (instead of the standard 90 degrees) to increase surface cooling and to reduce any "swooshing" noise associated with vented discs.

The recommended pads for use on the LRB rotors are the Lyndall Z+ units and the company even offers a little something rarely heard of nowadays: a lifetime warranty on the rotors if Z+ pads are used exclusively, provided there is never any metal-to-metal contact. Plus the Z+ pads require no break-in and are designed to have no squeal, so although they may appear a little pricey, properly maintained, you never have to buy another set. But if the guarantee isn't enough to impress you, the performance should.

That 1mm of additional rotor thickness was not as evident when I was only running the rear disc. But after I installed the twin set on the front, I had to endure somewhat of a learning curve on the quick response the added material provided. These beauties will haul the most fully loaded bike down from top speeds in a big hurry with only mildly applied pressure on the lever (don't grab a handful or you may end up ass over tea kettle). And repeated hard braking never gave any indication of fade from over heating . Being caught in several of those famous Texas spring from stranglers, I can also attest to the product's excellent rain performance. The rotors come complete with all mounting hardware (it's highly recommended to replace brake rotor bolting due to thread stretch that occurs during torqueing) and are exact replacements to their stock counterparts.

These units are available to fit all H-Ds back to 1984, as well as newer American IronHorse, Big Dog and Indian motorcycles (pricing is the same across the board). Lyndall's dealership network continues to expand and includes Drag Specialties, Bikers Choice and Riviera Engineering. Log onto their website to locate the dealer nearest you. In the end, I only had one complaint about the LRB Polished Stainless Rotors: once installed, these beauties looked so damn good I was shamed into cleaning the rest of the bike.
