The outfit rely on EBC XC-Series discs and GPFAX pads on their Aprilia race bike
Motorcycle race outfit, Brook Built Racing, has been competing in the No Limits Racing (NLR) SuperTwins series on a series of Aprilia RS660s, yielding great results by the end of 2024.
The team has entrusted EBC Brakes Racing’s XC-Series discs and GPFAX pads on their race bikes for a considerable time now.
The latest update comes after a trip to the gruelling Isle of Man TT race, where Michael Russell piloted his Aprilia to a trophy finish, securing fantastic results thanks to some sharp riding on the island.
Read how it all panned out in the team’s own words below…
TT 2025: Brook Built’s First TT – A Debut to Remember
“TT 2025 was a new chapter for Brook Built – and what a debut it turned out to be. While we’ve supported bikes at the Manx Grand Prix, this year marked the first time we entered and ran a bike in the full Isle of Man TT. There’s no other place like the 37¾-mile Mountain Course to test a builder’s work, and we came here with one goal: to see how competitive our Brook Built Aprilia RS660 SuperTwin could be against the best in the world.
“We teamed up with the hugely experienced Michael Russell – a name many of you will know from his all-classes challenge in 2023, where he competed in every solo and sidecar class. His knowledge of the course and adaptability made him the ideal rider to showcase what our machine could do.”
Practice Week: Weather, Wrenches & Wins
“Monday’s free practice session was cut short due to poor weather, but we did get the RS660 through scrutineering for the first time – a proud moment for all involved. Every TT session requires a full scrutineering check, so it was good to get that first one under our belts.
“Tuesday brought clearer skies, and Michael got his first laps in across all three bikes: the Superbike, SuperSport, and our SuperTwin. The SuperTwin and SuperSport sessions run together, so we made the smart call to put in one lap on each to help ensure qualification.
“In the first timed session, Michael clocked a top-20 lap on the SuperTwin with a 113.384 mph average – a very promising start.
“Thursday’s practice was cancelled due to weather, but that gave us time to sort some issues – tightening on the steering stem, a stripped wheel spindle, and an extended tank for 2 extra litres of fuel.
“Friday’s qualifying saw us improve again – Michael averaged 114.512 mph, placing us 30th.
“Saturday brought another weather-related delay, but we caught and fixed a small oil leak during scrutineering. Our final qualifying lap on Sunday earned us 23rd place and 26th on the starting grid for Race Day.”
Race Week: The Real Test
Superbike (Monday):
“Michael unfortunately retired on lap three due to an electrical issue, but showed great pace beforehand.”
SuperSport (Monday):
“Michael finished 21st with an impressive 118.802 mph average.”
SuperTwin Race 1 (Tuesday):
“Cut to 2 laps due to weather, Michael delivered a stellar ride from 26th to 13th place, with an average speed of 116.035 mph and a bronze replica to show for it. He reported brake drag, which we traced to a calliper anti-squeal spring and corrected ahead of the second race.”
SuperSport Race 2 (Wednesday):
“Michael brought the Fraser Evans GSXR750 home in 20th place at 119.664 mph – fast and consistent riding all week long.”
Thursday:
“Another washout. We went go-karting and visited Tony Bass at Slick Tuning”
SuperTwin Race 2: The One We Won’t Forget
“Friday’s three-lap SuperTwin race was our moment. Michael started strong, but during the fuel stop after lap one, we ran into a serious issue: the fuel tank wasn’t venting, creating a vacuum that made the cap difficult to remove. The tank had deformed slightly, and we couldn’t get a full refill in. Michael left pit lane not knowing he might not have enough fuel to finish – an incredibly tense moment for us all.
“As he passed each timing point on the final lap – Ballaugh, Ramsey, the Bungalow – we waited, watching. Then, finally, he came into view at Cronk-ny-Mona, down the straight and across the line.
“Against all odds, Michael brought the RS660 home in 13th place, securing another bronze replica – and proving both the rider’s skill and the bike’s resilience. He later confirmed he’d felt fuel starvation on the final lap, managing throttle and pace perfectly to finish.”
A Huge Thank You
“We couldn’t have done it without the team: Grant Evans, Andy Fenton, Charlie Eccott, Brad Burn, and Simon Rice – thank you for keeping us running when it mattered most.
“And to our sponsors – this was your TT debut too. Your support helped us reach the start line, and just as importantly, the finish line.
“This was just the beginning for Brook Built at the TT. With two top-15 finishes, two bronze replicas, and a ton of experience under our belts, we’re already looking ahead to the next challenge.
“See you on the Mountain again soon…”
