  • Ducati Scrambler Urban Enduro.

    Ducati India have launched yet another variant of their highly popular (abroad) bike, the Scrambler, called the Scrambler Urban Enduro. This new variant is priced at Rs 7.90 lakh (ex-showroom) and is now on sale. The Urban Enduro comes with a ribbed seat, an enduro-style handlebar, a cool green paint job, fork protectors, a motocrossstyle front fender, headlamp grille and 18-inch front and 17-inch rear wire wheels. These changes have resulted into a bike that looks even more retro than the standard Scrambler.
  • BIG BIKE VS. SMALL BIKE.

    We see it quite often at the racetrack, especially in club races where classes are mixed: Rider on small bike passes rider on big bike in seemingly every corner, only to be passed back right away on the next straight. Even if the power difference is not that great between the two bikes, the contrast between corner speed and straightaway speed of the two bikes becomes magnified as each bike is ridden to maximize its advantages. The reality of the situation is that the outright maximum cornering speed between any two bikes is not that significantly different, provided both are on similar tires. If the tires are similar, both bikes should be capable of the same lateral acceleration (limited by the friction coefficient of the tires) and corner speed. Why do we see such a contrast in how the bikes are ridden? On an underpowered bike, the quickest way around the track is to maximize corner speed, in turn getting onto each straight with as much speed as possible. This is accomplished by completing the corner with as large an arc as possible, which converts lateral acceleration into maximum corner speed. For a typical single-radius corner, this means entering as wide as possible to maximize entry speed, turning in to the apex with little trail- braking, and keeping the bike at maximum lean with a constant radius until the very exit of the corner. In contrast, the quickest lap times on a more powerful bike are usually found by maximizing acceleration onto each straight and taking advantage of that power; this is achieved by sacrificing some corner speed to pick the bike up and apply the throttle earlier at the exit. For that same single-radius corner, this means a tighter entry, more trail-braking to a slightly later apex, with a tighter arc and less corner speed to get the bike up off the side of the tire as quickly as possible. As we found out in our displacement test last year where we compared the Yamaha YZF-R6, Suzuki GSX-R750, and Kawasaki ZX-10R, it’s not so much that the smaller bikes have a handling advantage over the bigger bikes but rather it’s how each bike is ridden to play to its strength or weakness in the power department. Using data from our AiM Solo GPS lap timer, we could see differences in line and cornering speeds between the three bikes, just as you would expect given the horsepower of each. While a few horsepower here or there might not seem like it should impact line choice signifi- cantly, in practice even a small difference can significantly change how a particular corner or series of corners is negotiated. And the contrast between a lightweight bike and a literbike can be astonishing: We’ve encountered certain corners where the entry line is several feet different on an SV650 than it is on a 1000, for an example. Finding the optimum line to match the power of your bike does require some experimentation. The wide radius and high corner speed that less powerful bikes require typically brings with it a higher risk of a high-side crash in the middle of the corner just as the throttle is opened, and the safer option is to start with the tighter entry and lower corner speed of the big-bike line and work from there, adding more corner speed and a wider entry with practice. If you are looking at sector times on data, don’t forget to factor in any time gained or lost on the succeeding straight, which may or may not offset time saved in the corner itself. Given the contrast in lines between different bikes, the key point to remember is that the optimum line for your bike may be very different from the bike in front of you, and it’s quite often a mistake to blindly follow another rider at the track. Even if you are riding the same model of bike, the power difference may be enough that you can take advantage of a different line to be quicker, and that line may work to a further advantage when it comes time to make a pass. When you ride at the track, what bike you are on will at least in part determine what lines you should be taking, and you should try different options with that in mind. And if you change bikes and move to a more or less powerful machine- or even make modifications to the same bike for more power-know that the lines you had been using for years might need to be altered appropriately.
  • 2016 YAMAHAS.

    New, More Affordable R1S If there is any one downside to the continued evolution of sportbikes it’s cost: The more advanced production motorcycles become, the more expensive they become as well. And while for some that trade-off is justifiable, there are still those consumers who simply aren’t willing to gut their bank account for the exotic materials and technologies that make modern motorcycles the track weapons they are today. For those consumers, Yamaha has introduced its YZF-R1S, which uses cost-effective materials to cut the suggested retail price of the otherwise stellar R1 by $1,500, to “just” $14,990. If your immediate thought is that Yamaha must have taken everything that made the R1 great and thrown it out the door (electronics included), then rest assured that’s not necessarily the case. Instead, with the R1S, Yamaha has gone in and replaced the titanium connecting rods with steel ones and magnesium outer parts and fasteners like the oil pan and right-side engine covers to aluminum ones. Engine cover bolts are now steel instead of aluminum, while wheels are now manufactured from aluminum instead of magnesium and wrapped in Bridgestone Battlax S20 sport tires instead of the R1/R1M’s trackday-intentioned RS10s. The exhaust header piping is also now made from stainless steel rather than titanium. The overall result of all this material swapping is a 9-pound jump in claimed curb weight. The R1/R1M’s MotoGP-inspired electronics package with power modes, traction control, slide control, launch control, and wheelie control goes untouched, though on the R1S, the quickshifter will come as an option rather than as standard equipment. There are a few other changes, including updates to the ECU that are intended to suit the new engine specification. The switch to steel connecting rods from titanium in the R1S means the redline needed to be reduced, the result being slightly less top-end power than the standard R1. Yamaha has yet to quote any numbers, but in published dyno charts (which are devoid of any numbers), it appears that the R1S’s redline is at 12,500 rpm instead of the R1’s 14,000 rpm, with the power loss at the very top around 5 or so horsepower. The R1S is available in either a red/white/ black color scheme or matte gray motif, and the bike is expected to be available beginning in February. New XSR 900 and Updated FJR 1300 The growing “hipster/caf? racer” culture is catching the attention of the OEMs, with Yamaha and its new XSR900 for 2016 being the latest example. The XSR retains the FZ-09’s excellent 847cc crossplane three-cylinder engine and Controlled Filling Die-Cast aluminum frame and swingarm with adjustable KYB suspension but adds styling components and details that harken back to the “heritage, authenticity, and simplicity” of the sporting motorcycles from the ’70s and ’80s. The XSR gets the FZ’s three YCC-T (Yamaha Chip Controlled Throttle) riding modes, but it also gets a two-level (plus off) traction control system as well as ABS as standard equipment. An assist/ slipper clutch eases lever effort by a claimed 20 percent while also helping to smooth out downshifts. Everything else mechanically (save for suspension settings) is basically identical to the FZ. Ergonomically, the XSR’s 32.7-inch seat height is 15mm higher than the FZ’s, and the rider’s seating position is moved 50mm rearward to make for a slightly more aggressive riding posture. Styling is the XSR’s main focus. There’s plenty of nice metal bracketry and components where plastic or other materials would normally be used. For example, the nice-looking fuel tank cover on the matte gray/ aluminum version (there’s also one in the 60th Anniversary yellow/black traditional Yamaha motif) is a brushed-aluminum piece that Yamaha says has an actual hand-buffed finish. A single round halogen headlight is held by aluminum brackets, and a round LED taillight mounted atop a metal (aluminum) fender replicate the look of the ’70s caf? racer. The seat features burgundy-colored faux suede leather panels and red stitching. The single round instrument gauge recalls the older style in shape, but in function it jumps to present-day technology with a full LCD info panel. All told, the XSR900 comes in 16 pounds heavier than the FZ-09 according to Yamaha, at a claimed 430 pounds full of fuel. The matte gray/aluminum XSR900 will be available in April, while the 60th Anniversary version will be available slightly later this year in May. Also new for 2016 from Yamaha is the latest FJR1300, in both A (standard) and ES (Electronic Suspension) models. The biggest change for both editions is a six-speed transmission replacing the old five-speed, with a slipper/assist clutch. A new LED headlight and taillight along with slightly revised bodywork complete the revisions for the A model, while the ES gets all that plus a new “lean-angle sensitive” cornering LED light setup that uses three LEDs on each side above the quad-element headlights that light up progressively as the bike leans to more effectively illuminate the road ahead in corners. The 2016 FJR will be available in March; no prices for either the new FJR1300 or XSR900 were available at press time.
