  • Monster 1200R.

    The most powerful Monster yet, we rode this one in our November 2015 issue. According to our international bike guru Roland, the 1200R is the fastest, most aggressive and entertaining Monster yet.
  • 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.
  • Audi Q7 e-tron 3.0 TDI quattro.

    You’ve probably already read about Audi’s grand plans for electrification of its model range, and soon it’ll have a second plug-in hybrid model to sell alongside the A3 e-tron launched earlier in the year. This time around the German firm has taken a different route, pairing the 3.0-litre TDI engine from the Q7 with a 126bhp electric motor, which together develop a mighty 369bhp and 516lb ft of torque. Owners will be able to travel up to around 34 miles, depending on the climate, which Audi reckons will be just enough for the daily commute to and from work for the average motorist. Three intelligent driving modes - EV, hybrid and battery hold - can work in tandem with the navigation system for best efficiency thanks to what Audi calls a predictive efficiency assistant. The price tag for all of this technology has yet to be revealed, but is expected to be Ј60k after Government grants, which is a hefty premium over the regular diesel editions. For anyone that’s expecting to see a whole load of electronic trickery, you’ll be disappointed, because the Q7 e-tron looks decidedly like any other diesel Q7, though the instruments have been altered to take into account of the electric motor, including the excellent Virtual Cockpit fitted to our test car. Beautifully finished, soft-touch materials are used throughout the cabin, delivering a high quality ambience. While the driving position is suitably command-like, the height of the dashboard is relatively low and so isn’t quite as imposing as other large SUVs. Supportive seats, a wide range of adjustments to both the chairs and the steering wheel mean that just about anyone can get a comfortable driving position. The cabin is simply huge, and whereas conventionally powered Q7s come with seven-seats as standard, due to the hybrid gubbins, there’s just five here. But that’s just fine as there’s generous space to spread out both front and rear. Boot space is inevitably smaller, but just 120 litre have been lost due to electrification. That still leaves a sizeable 650 litres with the seats up, and an expansive 1,835 litres with the chairs down. Performance is effortless, with smooth, linear acceleration no matter which source of power is being used. While in electric-mode, it’s eerily quiet, with only a distant sound from the tyres to be heard. The engine cuts in almost imperceptibly, with none of the vibrations that rival hybrids were afflicted with. Even with the diesel engine in action, sounds are nicely muted, with the cabin of the Q7 a calm place to travel. There’s a fluid feel to the steering with nice weighting that allows for accurate, precise cornering, and despite its bulk, this e-tron Q7 feels relatively light on its wheels. It handles flatly with little sign of body roll, backed up with huge amounts of grip. The only fly in the ointment is that of brake pedal feel that at times doesn’t inspire total confidence. Ride comfort is impressive, delivering a magic carpet-like ride from its adjustable adaptive suspension.
