I always get a chuckle when I receive an email with “race-winning data” to look at, as if it is somehow different or special compared to, well…data that didn’t win the race. It makes me smile because quite often there is not much to be learned from such data, contrary…

Time and again on our short Canadian tracks, we have seen 600cc machines turn lap times close to 1000cc bikes, and well-ridden 600s have occasionally made it onto the Superbike podium. Given the huge horsepower advantage of the 1000, the 600 must be making up time somewhere to be so…
At the recent opening round of this year’s Mopar Canadian Superbike Championship at Shannonville Motorsport Park, I was at the track working with the Accelerated Technologies / Honda Canada team and Jodi Christie, using the team’s AiM Sports data acquisition system to help with setup.
Last week, it was announced that Dunlop will replace Pirelli as the official spec tire of the Mopar Canadian Superbike Championship, ending an eight-year relationship. And just the week previously, Bridgestone announced that it will be stepping down as the tire supplier for MotoGP at the end of the 2015…

With the snow disappearing and temperatures warming across the country, it's almost time for a new season of Canadian Superbike racing to get underway. Last year, I worked with Jodi Christie and the Accelerated Technologies/Honda Canada team and detailed much of what we accomplished in previous blogs and the October…
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,…
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…

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…
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…
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…
