Mackenzie has claimed 16 BSB wins in his five years with McAMS, having first joined the Raceways Motorcycles-run 🎐effort for the 2017🍎 Supersport season.

A perfect run of six BSS victories at the start of that year saw the reigning champion leave to take up an ill-fated Moto2 grand prix seat for the remainder of the season, but&n﷽bsp;he returned to McAMS for a BSB debut in 2018.

After winning the 2021 BSB crown with ten victories and 19 podiums, Mackenzie’s 2022 title defence w💃as blighted by leg fractures in the pre-season and later ended with a b൲roken femur at Oulton Park.

“I’ve known and supported Tarran since the early stagesꦦ of his career, so we are sad to see him move on for 2023 but wish him all the best in his next steps,” said McAMS Yamaha team principa⭕l Steve Rodgers.

“It’s been an incredible six years and we’re incredibly proud of what he has achieved ꧙as part of this team. It’s been a whirlwind few years with a lot of highs and some lows, but regardless of the situation, Tarran’s speed and sheer tenacity can never be questioned.
