  • V7 II.

    Moto Guzzi launched the new generation of the V7 at EICMA 2015, called V7 II, six years after the re-launch of the iconic motorcycle. Although a classic in its visual appeal, the V7 II is a modern motorcycle loaded with modern technologies. The bike is powered by Moto Guzzi’s new 744-cc air-cooled engine that puts out 48 PS at 6,200 RPM and 60 Nm of maximum torque at a rather low 2,800 RPM. Transmission is via a new six-speed gearbox as opposed to the previous V7’s five-speed unit. The clutch, too, has been improved with better linkages and modifications to the lever and cable in order to achieve a softer action and an even release. The bike should be headed to India soon and, once launched here, should make for an interesting choice in that segment.
  • DUCATI MULTISTRADAS.

    When I had a chance to try out the Ducati Multistrada Pikes Peak last year I was incredibly impressed, the concept of four bikes in one is bandied about quite commonly when referring to the Multistrada and is a good reflection of the bike’s abilties. The current Multistrada is a large bike with a wet weight of 235kg - relatively light all things considered. I found the seat height tall, although it is adjustable between 825 and 845mm and couldn’t get both feet flat to the ground, but balance and low speed maneuvering were both very good. Heated grips of a chilly morning are priceless and the centre-stand is a nice touch, although probably not for everyone. They are part of the Touring pack which includes heated grips, panniers and center-stand. The Multistrada S benefits from the Ducati Skyhook Suspension and also includes a few nifty additional features like full LED headlamps, including the Ducati Cornering Lights (DCL). The braking systems on the S is also an upgraded Superbike spec system, with M50 Brembo front calipers on 330mm rotors, with a dual piston Brembo rear caliper on 265mm rotor. Also standard is the Ducati Multimedia System, which uses Bluetooth to accept incoming calls, alert you to messages and control your music, when synced with your other devices, displayed via the S’s full colour TFT display. On the bike, performance from the DVT Testastretta starts low and tractor-like, with strong but controllable low end-torque, and between 4000 and 5000rpm transforms into sportsbike like drive - in fact if you want to move off in a hurry try opening that throttle wide open, it’s exhilarating. Just keep the revs up past 4000rpm where it transitions into much smoother running, with slight vibes felt through the ‘bars, but not in an annoying fashion - you’ll have all the torque you could wish for, for rapid overtaking or acceleration. You can also modify each of the riding modes for a variety of settings, where I was using the baseline settings, which means you can have each mode set up for specific conditions, whether that’s suspension, power delivery, ABS, DTC or DWC. The Skyhook Suspension was a standout and in Sport mode with one helmet (the one rider, no luggage setting) I could feel the forks providing more support during heavy braking, only to soften as I came to a stop. Through the local twisties the Skyhook suspension proved itself, with an ability to easily absorb road irregularities. Coming into corners needs more effort than your regular sportsbike, with the Multistrada obviously carrying its weight taller and taking more input to follow your chosen path. It wasn’t the sharpest on tip in, with the standard settings - but that’s something you can tweak thanks to the level of adjustability on offer. The taller bike also means you’re leaning over further, which was easy and confidence inspiring but lends itself to coming into your corners nice and wide.You can feel that you’re relying on a system of suspension that essentially has a mind of its own but as you get used to that fact and show more confidence in the bike it only gets better and better. Part of what sets the newest Skyhook Suspension (DSS) system apart is the Evo suffix, with the previous sensors now joined by the Inertial Measurement Unit (IMU) which is used to provide cornering ABS to the Brembo braking system with Bosch 9ME ABS unit. This means the DSS Evo system is able to take into account your lean angle when calculating the ideal suspension response. It’s high tech and the results on the road speak for themselves. I was hoping to take my wife for a ride as a pillion to get an opinion on riding two-up, but with all my testing mid-week unfortunately couldn’t make it happen. Now it’s quite possibly you’re thinking to yourself, why spend the extra $4000 on the S model, which is a fair question. The S is the obvious choice though, as the Multistrada truly is many bikes in one, with the S offering the ultimate in suspension adjustability at the click of a few buttons. It’s the future of motorcycling and Ducati’s leading the charge.
  • 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.
