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…
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…

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…
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…

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…
I wanted to steer away from all the excitement and glamour of racing in China and different countries around the world to talk about one of the amazing by-products of motorcycle racing. Yes, we all know the speed, excitement, and chasing for that win are all well documented reasons why we…

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…
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…
At the third round of the Mopar Canadian Superbike Championship held at Atlantic Motorsport Park, I continued working with Jodi Christie and John Sharrard with data acquisition on their Accelerated Technologies Honda CBR1000RR. At the second round held at http://www.insidemotorcycles.com/component/k2/item/1299-trevitts-blog-data-from-autodrome-st-eustache.html">Autodrome St-Eustache, we started using the AiM EVO4 system and spent…

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…
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…
In Part 1 of my 'Testing at Suzuka' story, I told you about the process of getting to the world famous Japanese track and getting prepped by a top notch team to test a top notch machine. Have a quick read of Part 1 if you haven't already, and then dig…

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.
I finally did it!  I completed a two-day test at the world famous Suzuka Circuit. This was a long time coming with tons of planning; nothing is ever spontaneous with the Japanese.  That is not a bad thing - in fact, when dealing with motorbikes and foreign countries, having a…
