One very powerful tool for data analysis - and a very necessary tool when dealing with more experienced riders or bikes close in performance - is the rate-of-change math channel. These math channels are generated by looking at how quickly a raw data channel changes over time, and show graphically how smoothly or how quickly that particular channel is changing. Here we are interested in studying that rate of change in very small slices, and the instantaneous rate of change of any particular channel can be found by taking its derivative.
In my last blog, I talked about working with Jodi Christie and the Accelerated Technologies Honda team in Canadian Superbike this year. At the second round of the series last weekend at Autodrome St-Eustache in Quebec, I had my first opportunity to see some data from the http://www.aimsports.com/">AiM EVO4 data acquisition system mounted on Jodi's CBR1000RR. As I mentioned previously, the EVO4 is a full GPS-enabled system capable of monitoring pretty much any aspect of the motorcycle you want.
At the opening round of the Mopar Canadian Superbike series at Shannonville earlier this month, Jodi Christie finished second in the Superbike race - just half a second behind multi-time champion Jordan Szoke.
At the recent Portimao round of the World Superbike series, the FIM, Dorna and the MSMA (manufacturers’ association) announced “a new framework for the Superbike Technical Rules” that will be applied in three stages, beginning next year.
In the May issue of the magazine, my article focuses on traction control systems and how you can make the most of their performance. Production systems and most (read: affordable) aftermarket systems are not at the level where you can let the traction control do all the work, and you must ride accordingly. While some systems are limited in their adjustment to the selection of one level from a limited number, many have more elaborate tuning parameters that can be changed.
Although the media spotlight does not shine as blindingly on the Ducati MotoGP effort now that Valentino Rossi has left the team, development continues and the company is working hard to improve its results in the premier Grand Prix class.
Part of that development involves the use of a "laboratory bike" with test riders Michele Pirro and Franco Battaini evaluating a constant stream of updates. Former FTR CRT rider Pirro raced the lab bike at the recent Jerez event, finishing 11th, and will compete in other races this year.
At the recent MotoGP event in Austin, Tex., Repsol Honda rider Marc Marquez became the youngest-ever rider to win a premier-class Grand Prix race, displacing Freddie Spencer from the record he had held for more than 30 years. It was the young Spaniard's second MotoGP race, and after two rounds he is tied with reigning champion Jorge Lorenzo atop the point standings.
Almost lost in BMW's celebration of Chaz Davies winning both World Superbike races at Motorland Aragon in Spain was Sylvain Barrier's victory aboard a BMW in the FIM Superstock 1000 Cup race at the same event. Barrier's win itself was not unexpected - the Frenchman is the reigning champion in the class - but the race marked a milestone in that Barrier rode a BMW HP4 equipped with DDC (Dynamic Damping Control), BMW's semi-active electronic suspension system.
In the current issue of Inside Motorcycles, my article covers some of the electric racing motorcycles and how improving battery technology is leading to some very different design paths from what we consider conventional.
One electric bike I find particularly interesting from a chassis design point of view is the Brammo Empulse RR. On that machine, the motor is located under the swingarm rather than in what we consider the traditional engine bay, and this turns out to be a favourable arrangement when anti-squat and chain pull is considered.
Dua Motorsports has posted a correction to its press release from last fall listing the winners of its 2012 Atlantic Roadracing League contingency program. The program offered contingency funds to the top finishers in the ARL Amateur Superbike division.
