Bridgestone CSBK Confirm Rules Updates for 2023 Season

Bridgestone CSBK National series organizers Professional Motor Sports Productions of Toronto, ON, have announced a series of rules adjustments and updates in advance of their 2023 National tour, scheduled to open May 19-21 at Shannonville Motorsport Park, just east of Belleville, ON.

Superbike Maximum permitted horsepower level increased

In 2023, the maximum permitted horsepower permitted for the top category in Bridgestone CSBK will be 210, an increase of ten horsepower over the maximum allowed at CSBK events during the past decade.  This information will be gathered using the official series Dynojet Dynamometer, supported by Pickering, ON., tuning emporium Brooklin Cycle Racing.

“When we begin to see motorcycles regularly get close to the horsepower limits, we discuss a possible increase with our manufacturer partners,” explains CSBK founder Colin Fraser. “The previous limit was established by the arrival of the second generation BMW S1000RR, and since then we have seen Superbike outputs gradually increase.”

Yamaha’s triples approved for Pro and Amateur Sport Bike

A recent update in the Sport Bike category guidelines opened up the class to the Ducati Panigale v-2, and now Yamaha are offering another engine configuration for the 125-horsepower category.  The family of Yamaha’s popular 890cc three cylinder offerings, including the MT-09, MT-09 SP, Tracer 9 GT and XSR 900 are now approved for competition in the middleweight division.

Currently, the pace setters in the Sport Bike class include Kawasaki’s ZX-6R Ninja, Yamaha’s YZF-R6, Suzuki’s GSX-R600 and the Honda CBR600RR.  Changing emission and related standards mean some of these machines are no longer available as new models on the show room floor in Canada.

Recently, CSBK confirmed that a new category, Pro Twins, would race in conjunction with Liqui Moly Pro Sport Bike in 2023, and be included in TSN network coverage.

CSBK drops minimum age one year for Super Sonic Road Race School Amateur Lightweight Sport Bike

In 2022, the youngest racers permitted to take part in any CSBK Series class were required to be a minimum of 15 years of age, but that will change for the upcoming season.  In 2023, the minimum age to participate in the initial entry category only, Amateur Lightweight Sport Bike, will be 14 – one year younger than previous.  Super Sonic Road Race School have sponsored this category since 2020, and also organize the popular Canadian MiniSBK Series and the Canada Cup for Ohvale mini-race bikes, based at Lombardy Raceway.

Guidelines Relaxed for Yamaha YZF-R3 airbox in Lightweight Classes

Yamaha’s middleweight twin, the YZF-R3, is a popular choice for competitors in Amateur Lightweight Sport Bike and the Pro-AM Lightweight division.  For the 2023 season in those two similar categories, competitors using the YZF-R3 will be permitted to modify their airbox lid and inlet air funnels, in a manner similar to that specified GYTR Engine Kit Manual for the R3.  Maximum allowable horsepower as registered post session in the official series Dynojet Dyno will remain at 44, the same limit required for the current “index” machine for the Lightweight categories, the Kawasaki Ninja 400. 

Pro Twins Initial Rules Package Released

In 2023, the new Pro twins category will run in conjunction with Liqui Moly Pro Sport Bike races at all rounds of the Bridgestone CSBK National tour.  The initial rules for the new category, deemed a class in development by CSBK, are now available covering Aprilia, Yamaha, Kawasaki and Suzuki twin cylinder machinery.
