Whether you’re riding your motorcycle to work, blasting through the canyons or piling on odometer numbers during your weekend getaway, your tires have got to do it all. Not only that, they’ve got to provide thousands of worry-free miles regardless of 40-degree temperature, rain or pavement-melting 120-degrees. Sounds like the type of conditions best suited for the new Metzeler Roadtec Z6 Interact sport-touring tire.
The Metzeler Roadtec Z6 Interact's use a uniform compound thoughout the tire. For our test, we mounted a set of Z6 Interacts in the original sizes (120/70-17 front and 180/55-17 rear) on our 2009 Moto Guzzi Griso. Tire pressure was set at 32 psi front and rear per Metzeler’s recommendations. The Z6 Interacts replaced the more sport-oriented and OE-fitted Metzeler M3 Sportec tire, thus giving us a unique comparison opportunity. Warm and sunny weather greeted us as we departed from the oasis-like surroundings of Palm Springs, California. We headed east through the neighboring cities of Rancho Mirage and Palm Desert, veering north onto Highway 74. Once on the 74 we climbed from the desert’s sea-level elevation and into the surrounding mountains of the San Bernardino National Forest. For the first few miles the road is perfectly straight but a few miles after you leave the perfectly manicured lawn of the city the road starts to zigzag. Fast corners immediately greet as you start up the mountain. And with the throttle wrapped-out in fourth gear it became immediately apparent of the high amount of outright grip from the tires. Just 15 miles before the tires were brand-new and within that short amount of mileage they were fully up to operating temperature and ready for as much lean angle as I could serve up. Contrary to my assumptions, based on the tires tech specs, at speed, with the motorcycle cranked over on the edge of the tire, the Interact’s feels firm without a hint of tire flex. Yet there is a suprising amount of road feel delivered especially at the front tire during trail braking. So much in fact that it makes you wonder if these tires are more aligned with the sport segment rather than touring. As we moved closer to the top of the mountain, the long sweeping, 100-mph turns began to transition into tighter second and third gear corners which required us to repeatedly maneuver the bike from side-to-side. Here the Interacts complemented the Griso’s nimble handling attributes and continued to impress by not requiring any additional effort than the tires it replaced.
The service life of the tires is still up in the air, but Metzeler claims it remains the same as before with the Roadtec Z6 tire.Shortly after we had reached the Santa Rosa Summit (approximate elevation 5000 feet), we headed west on Highway 371 through Anza, California. Here we piled on the miles on mostly smooth, straight road. Every so often a patch of rough pavement would surprise us due to the area’s extreme temperature variation between 100-degree summers and, at times, below freezing winters. Based on the tires firm feel in the corner I had presumed that it would be equally as firm when rolling over rough stuff. Not so. The Interacts absorb pavement imperfections agreeably, delivering a smooth ride while assisting the bikes suspension in keeping the tire in contact with the road. One particular straightaway allowed for a top-speed run and even with 130-mph registering on the 500-plus-lb Griso’s dash the bike was solid. In fact, with the previously fitted tire we noticed a hint of twitchiness when going over 100 mph, but with the Z6 Interacts that peculiar trait vanished. Although we didn’t encounter any wet weather along our route, we did run into some during last year’s Expert on the Road adventure. One particular moment hard-wired in my brain is that of myself and two other riders leaving the rest of the group as we sped up a tight, winding, first or second gear rain-soaked road as we closed in on Switzerland’s Sustenpass. The motorcycle I was riding, a Honda VFR800 Interceptor shod with the Z6 Interact. The three of us ran up the road at a ridiculous pace considering the sketchiness of the road, yet none of us had even a slip. When it comes time to plop down the cash for new tires, next to sheer performance the biggest consideration in the tire you choose is its mileage. Unfortunately we’ve only been able to log around 500 miles on the tires, so its mileage endurance is still a question. Nevertheless, Metzeler claims mileage remains the exactly the same as the previous generation Roadtec Z6 tire.Arguably, sport-touring tires are the most difficult tires to develop. Yet once again Metzeler steps up with a tire that absolutely hauls out on the road. So are these tires for you? Can you toss them on your Suzuki GSX-R1000 street bike? If you’re looking for a tire that will last longer than the stockers that came on your bike yet still give you the performance you need on the streets, regardless if it’s wet or dry, hot or cold than the Metzeler Roadtec Z6 Interacts are for you.






Dalam ilmu marketing, konsumen yang memiliki preferensi demikian besar terhadap sebuah merek disebut menganut brand cult. Demikian cintanya mereka pada merek tersebut sehingga kepemilikan terhadap produknya memberi kepuasan yang luar biasa melebihi fungsi praktikal yang diberikan. konteks otomotif roda dua, Ducati dan Harley Davidson dianggap mewakili produk dengan konsumen yang luar biasa fanatiknya.
Super sport bikes (also known as middleweight sport bikes) are designed for optimal performance on a race track. They are generally built around a high revving, small displacement powerplant that is usually sized around 600 cc (36.6 cu in) to 800 cc (48.8 cu in). Most super sport bikes will carry a wet weight between 375 lb (170 kg) to 450 lb (204 kg) and produce around 110 bhp (82 kW). Because of how strongly focused super sport bikes are on race track performance, riders below 5 ft 3 in (1.6 m) in height will generally not be able to flatfoot (the placement of both feet completely flat on the ground while sitting on a motorcycle) these types of sport bikes. Taller and heavier riders may find the rider ergonomics in the default position to be cramped and uncomfortable. 




Working bikes: Generally below 250 cc (15.3 cu in) and low-powered for commuting and utility travelling.
Kawasaki Z1, however, with its 900 cc (54.9 cu in) DOHC engine finally started the era of the modern sport bike. The Z1 sold so well that by the end of that decade the Japanese manufacturers were all building competing machines similar to the Z1 with its DOHC inline-4 engine configuration. The resulting "bike war" among the Japanese manufacturers and required investment in modern engine manufacturing contributed to the demise of the flagging British motorcycle industry.
Entry-level
Entry-level sport bikes are designed to introduce motorcyclists to the sport bike design. They are relatively inexpensive, lightweight, and durable. There are minimal to no fairings installed to cut down on cost and maintenance if the motorcycle is dropped. Although capable of more power, the engines are usually detuned for longevity and durability. Entry level sport bikes can usually accommodate riders of all heights and weights.

Super bikes are large displacement super sport bikes. They have characteristics similar to the smaller super sport bikes which are mainly focused on race track performance, but are powered by larger engines that are usually sized around 800 cc (48.8 cu in) to 1,200 cc (73.2 cu in). A typical super bike will carry a wet weight between 400 lb (181 kg) to 480 lb (218 kg) and can produce 180 bhp (134 kW). Super bikes with a displacement very close to 1,000 cc (61.0 cu in) are sometimes referred to as litre bikes. Motorcycles in this class are usually eligible to participate in Superbike racing.
Main article: Sport touring
Sport touring bikes are designed for riding longer distances, and are typically more comfortable than the average sport bike. Sport touring bikes are typically heavier, less powerful, and less performance-oriented than super sport bikes, but have more storage space, more comfortable rider ergonomics, and better practicality. Depending on the emphasis on these touring capabilities, sport touring bikes can range from super sport bikes with more comfortable rider ergonomics to full-featured touring motorcycles with sport bike-like capabilities and features.
