Bridgestone CSBK Tech Updates from Shannonville Opener

Macrae quick on track, powerful on Dyno

Friday practice and qualifying at the opening event of the 2023 Bridgestone CSBK Canadian Championship national series produced a trove of data for the Professional Motor Sports Productions technical staff at Shannonville Motorsport Park east of Belleville, ON.

The first timed event of the afternoon was for the Liqui Moly Pro Sport Bike category, including the new Pro Twins development class for the first time. Second year pro Brad Macrae was quickest on his Colron Excavating Yamaha YZF-R6, with a lap at 1:07.781.  

Macrae missed the final events of 2022 recovering from injuries suffered at the July national event at Atlantic Motorsport Park, Nova Scotia. 

In post race technical inspection, Macrae’s middleweight machine weighed 364 pounds, safely under the minimum prescribed amount of 350 on the official series scales. Next Macrae’s mount went to the series’ official Dynojet Dyno, operated at national events by Brooklin Cycle Racing of Whitby, ON.

Macrae’s Yamaha “spun the drum” to register 121.41 certified horsepower, a strong number but safely under the allowed maximum of 125 HP. 

Most impressive performance was the fourth-quickest effort posted by series newcomer and track rookie John Laing, of Cochrane, AB. Riding the Vass Performance Kawasaki ZX-6R Ninja, Laing did a lap in 1:09.086, and then put out a solid, and close, 124.75 horsepower on the Dyno, and tipped the scales at 370 pounds.

For 2023, the Liqui Moly Pro Sport Bike category has updated rules that includes the homologation of the Daytona-winning Ducati 955 v2 Panigale Desmo. 

Early in Friday’s second day of action at Shannonville, Elliot Vieira of Claremont, ON, and born in Guyana, had his brand-new GP Bikes-backed Ducati register just over 122 horsepower on the official series Dynojet Dyno. Vieira qualified eighth, while the top Ducati was Nathan Playford of Kitchener, ON, in sixth.

Meanwhile, leading Pro Twins entrant in that brand-new category was Kingston, ON-based local hero “Jammin’ Jeff” Williams, a former Pro Superbike race winner. On a brand-new Aprilia RS660 twin, Williams’ entry registered 86.69 horsepower, safely beneath the 90 permitted maximum. His machine weighed in at 361 pounds, eleven above the lowest permitted figure.

Top Suzuki SV650 twin belonged to Andrew Van Winkle from Chilliwack, B.C., the class staple entry putting out 81.64 horsepower with a weight of 373 pounds. Van Winkle is yet another promising young entry joining the Bridgestone CSBK tour from Canada’s western provinces.  

In the premier rider development class, Super Sonic Road Race School Amateur Lightweight Sport Bike, former U.S. Aprilia Cup racer Jack Beaudry of Lorette, Manitoba, took his Kawasaki Ninja 400 to an impressive pole with a time of 1:15.626.  

Post qualifying, his machine put out 44.31 HP, close to the limit, and weighed in at 329 pounds, wet, post session.

The other much anticipated rookie in the class, 2022 MiniGP Champ Vincent Lalande from Boisbriand, QC, was 0.607 seconds behind fellow rookie Beaudry on his Kawasaki. Lalande’s Ninja pumped out 44.38 horsepower on the Dyno and registered a weight of 323 pounds. Both Beaudry and Lalande are making their first racing starts at Shannonville.

Top Yamaha YZF-R3 twin in Amateur Lightweight Sport Bike was MiniGP Senior Official Justin Marshall, the chef from Crysler, ON, earning fourth overall. Marshalls’ machine tipped the scales at 331 pounds and ran at 40.14 horsepower on the Official Series Dynojet Dyno.

Saturday’s opening day of Canadian national racing for 2023 will include featured races for the GP Bikes Pro Superbike category, Liqui Moly Pro Sport Bike and Pro Twins, EBC Brakes Pro-Am and the Super Sonic Road Race School Amateur Lightweight Sport Bike division. The full seven National events will take place on the Sunday of Victoria Day weekend.
