Hamilton, Ontario – Another new category will enter the Bridgestone Canadian Superbike Championship in 2024, open to near-stock Kawasaki motorcycles focused on the all-new 399cc, in-line four-cylinder ZX-4R and ZX-4RR models.
The Kawasaki 400-4 Cup will run in conjunction with the updated Pro and Amateur Twins category on-track this season, but feature separate scoring and results. Pro Twins ran together with Pro Sport Bike during their debut season in 2023, but now they will join the new Amateur Twins class and the spec Kawasaki 400cc-four category to race together in 2024.
Both Twins classes and the Kawasaki Cup category are classified as “Pro-AM”, meaning riders will compete for one podium and one set of trophies per race, but are scored separately in terms of overall series championship points standings. This means each race for Twins/Kawasaki Cup will feature two podiums: one for Twins, and one for the ZX-4R/RR class.
Modifications to Kawasaki ZX-4R and ZX-4RR machinery will be limited, and these adjustments must fall in line with the existing rules for the Amateur Lightweight Sport Bike category.
All Kawasaki ZX-4R Cup competitors will be required to use Gulf Classic fuel, the lower-cost version of two fuel options provided by new spec fuel provider Gulf Race Fuels.
Maximum horsepower as measured on the official series Dynojet Dyno, (operated by Brooklin Cycle Racing of Pickering, ON) will be 75 HP, checked immediately post-race. An aftermarket slip-on exhaust silencer will be permitted, and a reflash of the stock ECU (Electronic Control Unit) will also be allowed. These figures may be reviewed mid season as development continues.
As with every other category in Bridgestone CSBK, the Kawasaki Cup Competitors will also have to meet a minimum post-race weight limit. In the case of the ZX-4R and ZX-4RR, this weight will be 350 pounds, immediately post-race, as measured on the certified CSBK official scales at Keene Truck Technical Inspection.
Each Kawasaki 400-4 will run on identical spec Bridgestone tires, mounted on stock rims. Competitors are restricted to two sets of tires for use over the course of the typical three-day event, beginning with round one at Shannonville Motorsport Park on Victoria Day weekend, May 17-19.
Otherwise, the new Kawasaki spec machines will be near stock, with other mods only permitted to brakes lines, brake pads, front suspension internals and rear shock absorbers.
Aftermarket handlebars and controls are permitted, and race fairings with the ability to control fluids are required. A front brake lever guard and rear swingarm “shark fin” are also mandated, as with all other CSBK classes.
The most recent spec category hosted by CSBK was the Kawasaki Ninja 300 Series – the precursor to the current Pro-AM Lightweight and Super Sonic School Amateur Lightweight Sport Bike classes – which raced nationally in 2016 and 2017.
CSBK has also hosted national championships for Honda with 125cc and 250cc capacity, the Suzuki SV650 Cup, and the Yamaha RZ350 Challenge. All of these categories were strictly regulated, with the goal of developing young Canadian racing talent.
Many top competitors have come from these various “spec” series, including Hall of Famers Miguel Duhamel and Pascal Picotte, as well as current CSBK stars and national champions Tomas Casas, Stacey Nesbitt, and David McKay.
More information can be found on the series’ official website at CSBK.ca.

Daytona Beach, Florida – Pfaff Motorsports took the green flag at the 2024 IMSA WeatherTech season opener at the Daytona 24 Hours and wasted little time moving up from its sixth-place starting position to the lead by lap 55 of the twice-around-the clock event.
The record-setting crowd saw witness to the debut of the Driveway 720S GT3 EVO in impressive fashion, as driver Oliver Jarvis (UK) vaulted the team up five positions in the GTD Pro class, and 11 positions in the GTD category by lap 25 of the 791-lap total race distance, an incredible feat for the Canadian-based sportscar team. Pfaff Motorsports had run the new McLaren for the first time just one week prior, at the ROAR preseason test.
That momentum continued as Jarvis handed the 720S to fellow full-season Pfaff driver Martin Kirchöffer (DE), but nearing the end of his stint four-and-a-half hours into the race, the McLaren suffered a right front upright failure, forcing the team to limp back to the garage where they sprinted through a 39-minute repair to get the car back on track.
In a 24-hour race where anything can happen, Pfaff’s crew never wavered, leaning on both the impressive performance of the 720S GT3 EVO and its strategy to help get back into contention for a repeat of the team’s 2022 Daytona 24 Hour win.
Fighting into the evening, the team suffered yet another blow just after midnight on lap 291, when a starter issue froze the McLaren in the pits, forcing the team back to the garage for another 38-minute repair – putting them 43 laps down from the lead.
With victory seeming out of sight, Pfaff remained in the points hunt for their full-season championship fight, setting impressive lap times throughout the late hours and into the early morning, until at 8:40 am ET on lap 532, the McLaren suffered a powertrain failure that forced the team to retire from the race with just 5 hours remaining.
Steve Bortolotti (general manager)
“This was definitely one of the toughest 24 Hours we’ve had here at Daytona. We knew coming in that we would have our work cut out for us, given that we ran the car for the first time here last week at the ROAR [preseason test], but despite that, Ollie [Jarvis] and the team showed what this McLaren is capable of in race conditions.
“The team gave it everything and I couldn’t be more proud of what they were able to do despite everything that was thrown at them, so a major kudos to everyone for laying it all on the table to give us a chance to fight for the points. We’ll have a major post-op and address these issues to come back stronger and harder at Sebring.”
Oliver Jarvis (driver)
“From the start of the race, the car felt good. It’s impressively quick, so we were optimistic from the start that we could be fighting for the win. Unfortunately, there were just too many issues to overcome, but the team did an amazing job keeping us in for as long as they did, so we look forward to Sebring and getting back into it there.”
Marvin Kirchöffer (driver)
“It was a difficult race, no doubt. But as the first race with this new team and a brand-new car, we showed a lot of promise for what’s ahead. I can’t wait to get back to Sebring to show what we’re capable of.”
James Hinchcliffe (driver)
“This one stings for sure. The car was so quick, and it was easy to get excited for what was unfolding for the 24 hours. Unfortunately for the guys and girls, this just wasn’t our race, but it was a massive effort from everyone to give us a chance and put some positive laps into the car. I’m looking forward to getting back with everyone and seeing what we can do at Sebring, because while it was a tough race, there have been a lot of positives to take from this one.”
Alexander Rossi (driver)
“We definitely had our hands full here [at Daytona], but throughout the last two weeks, this team has shown time and time again why they are champions and a threat no matter what is thrown at them. Coming in as a driver to a new team with a new car in the biggest race of the season, all I can say is their efforts are inspirational. I can’t thank them enough for making this an easy transition, and I’m excited to see what the future has in store.”
