With less than two weeks before the first event of the MotoGP season, Dorna is set to introduce a new sub-category in the MotoGP class, dubbed Factory 2. It seems unbelievable that this would be the case when the goal for the class, as stated by Dorna CEO Carmelo Ezpeleta, is to have one category...

The recent MotoGP test at Sepang, Malaysia, provided the first real chance to see how the new rules for 2014 have changed the structure of the class and how the performance of the various machines compares. Since 2012, the class has been filled out with bikes under the CRT (Claiming Rule Team) clause, which ostensibly...

In the current issue of the magazine, my article covers the importance of thrust, or actual driving force to the rear wheel, and why it is an important measure. You can find an Excel file to make your own thrust chart (and other helpful downloads) http://www.datamc.org/downloads/">here. Thrust and anti-squat are related because it is driving...

I have talked several times before about dynamic geometry and how rake and trail change as the motorcycle goes around the racetrack. Under braking, weight is transferred to the front end, compressing the front suspension and decreasing rake and trail measurements. Likewise, weight transfer to the rear under acceleration causes the front suspension to extend...

As I mentioned in a previous blog, recent advances in tires, chassis and electronics have put more emphasis on corner entry and trail braking rather than corner exits, as this is currently the part of the track where riding skill and technique can make the most difference.

In my previous two blog postings, I have covered the importance of corner entry and the actual mechanics of how to trail brake into a turn and improve that particular skill. This week, I will show some data from a GPS-based lap timer that can be used to keep track of your progress.

In my last blog I talked about trail braking and why it is such an important skill to learn, but I didn't go into the actual mechanics of the technique, or how to learn and improve at it. To recap, trail braking refers to trailing the brakes as you lean into a corner, so that...

As I work with more riders using data acquisition and look at more data, the common theme that always rises to the surface at some point is turn entry and trail braking - holding the brakes on while leaning into the corner.

A video released by MotoGP last week (See bottom of the page) shows Jorge Lorenzo's Yamaha YZR-M1 in pit lane leaned over on its side to the same angle it reaches on the track - 64 degrees from vertical. It's an incredible sight when shown in this manner; the bike is essentially laying on its...

Watch any motocross race and you will see the riders going far out of their way to take advantage of a berm, or completely missing the apex of a turn to ride on the out outside, banked portion. This shows the importance of elevation changes for quick lap times in the dirt. But while the...

The recent events in the Canadian Superbike series at Canadian Tire Motorsport Park and Le Circuit Mont-Tremblant have prompted me to address the safety benefits of using data acquisition, which are often overlooked and deserve more attention. While I did not know Christian Auger or John Ross MacRae, my thoughts and sympathies are with their...

At the recent Canadian Tire Motorsport Park rounds of the Canadian Superbike Championship, I was at the track helping Jodi Christie, John Sharrard and the Accelerated Technologies/Honda team and continuing my work with the their AiM data acquisition system. At the previous round we had concentrated mostly on suspension setup for the CBR1000RR, and the...
