Trevitt’s Blog: Electromagnetic Valve Control (video)

Graeme Jones — Mon, 31 Oct 2016 21:47:28 +0000

While variable valve timing has been a hot topic over the last few weeks with the introduction of the updated GSX-R1000 featuring Suzuki's innovative mechanical VVT system, many companies are working toward the next step in this area: eliminating camshafts completely and controlling the valves directly using electromagnetic actuators. There are many stumbling blocks to electromagnetic valve actuation (EVA), but a research group in the Control and Automation Laboratory of the University of British Columbia has created a new type of actuator that may make EVA a very realistic option in the not-too-distant future.

Trevitt’s Blog: What’s a Qualifying Tire Worth?

At the final rounds of this year's Mopar Canadian Superbike Championship series, held at Canadian Tire Motorsport Park, Dunlop offered qualifying tires to the top 10 riders for a separate, 15-minute final qualifying session. This was new for many of the competitors, as qualifying tires have not been used in the series for several years. Jeff Williams was one of the riders in the top-10 session, and I was able to get some data from the Accelerated Technologies Honda CBR1000RR that he was riding for the weekend.

Andrew Trevitt’s Blog: Transfiormers – Daring to be different in a sea of Moto2 uniformity

Last month, Spanish rider Ricard Cardus won an FIM CEV (Campionato Espagnolo Velocita, a European Championship) Moto2 race at Catalunya in Spain. That in itself is not overly surprising; Cardus has been racing in the Moto2 World Championship for several years with a handful of top-10 finishes to his credit. What's more noteworthy is the motorcycle he was aboard: Transfiormers.

Trevitt’s Blog: Backing it in

Andrew Trevitt — Sat, 28 May 2016 01:47:58 +0000

We see all the time now road racers “backing it in” to corners, sometimes with the rear end of the motorcycle out of line with the front just as much as dirt track or supermoto racers. Using engine braking or the rear brake, these riders are skidding the tire just enough that the rear end […]

Trevitt’s Blog: Anti-Squat in Theory and Practice

Andrew Trevitt — Fri, 01 Apr 2016 23:25:40 +0000

In previous blogs, and in the print version of the magazine, I have discussed anti-squat and how it relates to chassis setup. Anti-squat is a very important tool in making a motorcycle lap quickly at the racetrack, especially a powerful superbike, but at the same time it’s one of the least understood setup parameters. Some […]

Trevitt’s Blog: Learning a new track – Castrol Raceway in Edmonton

Graeme Jones — Fri, 17 Jul 2015 22:04:52 +0000

In 1990, I raced at Road Atlanta in the AMA 250 Grand Prix class. Since it was a new track for me, my brother Stephen and I drove down early so that we could at least get a look at the track before practice.

Trevitt’s Blog: Rossi Redoubled!

After four rounds of the 2015 MotoGP season, Valentino Rossi sits atop the standings, with two victories and four podium finishes to his credit. While the Movistar Yamaha rider has definitely taken advantage of his competitors' various misfortunes in the opening rounds, he has just as definitely shown he is capable of winning in a straight-up battle - as he did in convincing fashion by outfoxing Marc Marquez in Argentina.
