  • 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.
  • Aprilia RSV4 R-FW.

    For those who think good just isn’t good enough, Aprilia has released more information on a “Factory Works” program that will enable riders or teams to buy an RSV4 built by the manufacturer’s racing department. While the program is primarily intended to keep Aprilia’s RSV4 on race grids around the world, it is also a chance for (very) serious trackday enthusiasts or collectors to stake their claim on Aprilia Racing Division’s years of hard work and development…for a price, of course. No word just yet on what that price will be, though Aprilia did confirm that the RSV4 R-FW will be made available in five packages (each varying in terms of specification for engine and electronics), with the top packages featuring special electronics systems and an engine with upward of 230 hp.

  • 2016 Honda CB500F and CBR500R (shown).

    Honda has made small tweaks to its self-described “fun and affordable” CB500F and CBR500R models, which for 2016 feature moreaggres sive styling for an overall sportier look. In addition to the updated styling, the CB500F and CBR500R both get a new muffl er for better mass centralization, lighter weight, and improved sound, a larger fuel tank, adjustable front brake lever, preload adjustment for the front suspension, and transmission updates that result in smoother shifting. Availability is early 2016.
