The 2011 Blackline Softail keeps the faith in Harley’s Dark Custom lineup. |

Metzeler’s new Sportec M5 Interact, complete with 5-stage lean-angle indicator and a pesky elephant. |

Varying tension of the Interact’s zero-degree steel belts optimize them for the differing loads subjected to each part of the tire. |
BMW’s oddball HP2 Sport provided our first chance to assassinate Metzeler’s elephant. |
A light rain fell on our session aboard the racy Yamaha R6, but the fun continued unabated. |
More Grip Than You Think |
The difference between a motorcycle having enough traction and not having enough can be teensy, but the consequences of loosing grip can be considerable. This is especially evident when riding on wet roads. To show how much traction the Sportec M5s offer in drenched conditions, Metzeler set up a braking course in a downpour for us to sample a BMW S1000RR. Naturally, the Beemer was equipped with its antilock brake system so we wouldn’t do any helmet surfing.We brought the S1000RR up to about 55 mph, and then – taking an electronic leap of faith – hammered on the front brake lever as if about to rear-end a Hummer. I knew I was going to be impressed how quickly an ABS-equipped bike can be slowed in the wet, but the rate of deceleration was nothing short of incredible. The ABS gave supreme confidence, and the tires produced mind-bending traction levels that got the bike slowed quicker I thought possible on a wet surface. But was this astounding performance due to the tires or the ABS? Well, being able to stab the brakes like an idiot, on a wet road, was only possible due to the ABS, as even full-on rain tires wouldn’t be able to withstand such ham-fistedness. But worthy of note is the eyeball-bulging deceleration enabled by tires that offered the traction necessary to make it possible. ABS skeptics who ride in the rain would be enlightened by a test such as this. |
Traction control and antilock brakes: Duke gladly takes all the help he can get! |
This is how dry we wished Portimao was for our S1000RR sessions! |
The handling and grip performance of the new Roadtec Z8s was impressive no matter what model bike I was riding. |
The Z8s on BMW’s K1600 are specially-constructed to better handle the bike’s additional weight. |
Metzeler Roadtec Interact Z8 Pricing | |
Front Tires | $174 - $179 |
Rear Tires | $209 - $270 |
The 1.7 miles of Auto Club Speedway’s infield road course would play host to our Oddball Sportbike shootout this year. Who’s your money on? |
Carving corners and ripping up racetracks are just two of the 675R’s specialties. |
The harder we ride the 675R, the bigger our smiles become. It’s that much fun to ride. |
So familiar is Pete with the GSX-R750 that this picture was taken on his very first lap of the day. Okay, not quite, but we all quickly got up to speed on the obedient Gixxer. |
At the end of the day, all three testers set their fastest times aboard the Suzuki. |
As competitive as this field of three was at the racetrack, Suzuki’s GSX-R750 distinguished itself as a cut above each time we rode it. |
Bridgestone Battlax R10 |
As motorcycle manufacturers are constantly pouring money into research and development to make their machines go faster around a track, tire manufacturers are also devoting time and resources to ensure the rubber that meets the road can handle these new technologies. New from Bridgestone, for example, is the the Battlax R10. Utilizing the experience gained from being the sole tire provider in MotoGP, the R10 replaces the BT003 as Bridgestone’s premier D.O.T.-approved racing tire. An all-new tread design incorporating 3D grooves maximizes stability under braking and acceleration, while the carcass of the tire utilizes “flexibility-optimized construction” to help it come up to temperature quickly and provide maximum grip. Profile shape for the R10 assumes a broader stance, moving away from the more triangulated profiles from years past. Bridgestone says the vertical grooves in the middle of the front tire “optimize steering angle” at slight lean, while they “enhance grip performance” and help make slides easier to manage in the rear. Bridgestone also uses a Mono-Spiral belt — a single strand of cord around the circumference of the tire — to minimize tire growth at high speeds. Bucking a trend used by other tire manufacturers, the R10 does not use multiple-compounds in a single tire. A medium compound is the only front tire option, while medium or hard options are the choices for the rear. Bridgestone contends that the R10 doesn’t need multiple compounds because they’re made to be effective in a wide range of conditions. The company also claims a big improvement on initial grip compared to the BT003, plus a higher overall grip level that’s sustained for the same, if not longer, period of time than its predecessor. Bridgestone sent us the hard compound rear tire for our track day, taking into consideration the hot ambient temperature at the California track. Tire warmers weren’t used during our testing, yet it only took one full lap to bring the tires up to temperature. Feedback from the tires was excellent, though Duke did notice that at the recommended cold tire pressure of 28 psi front and 27 psi rear, all three bikes were slower to steer compared to the day prior on our street ride. For that we had the tires inflated approximately seven psi higher at each end. We were really impressed by the edge grip offered by the ‘Stones and even more impressed with its durability — after more than 100 miles of racetrack thrashing, the R10s maintained their high grip levels the entire day without a single slide or protest. Rest assured, we were worn out well before the tires. Bridgestone has a winner in the new R10. Whether you’re a racer fighting for wins or a trackday junky looking to get the most out of your tires, the R10 is the real deal.

The EVO exhibits uncharacteristic power traits for a V-Twin. With the bulk of its power coming high in the rev range, we found ourselves riding the Ducati like an inline-Four. |
The Ducati’s sinister matte-black paint job is $1000 less than the red or white offerings, but it’s difficult to photograph without looking like a black blob. |
As it stands, the Ducati falls short of matching the lap times of the other two around a tight track. Note the undertail mufflers, which are 2 inches longer than on European-spec 848s. |
