The Hydrex team is headed up by Team Principal Shaun Muir, who after retiring from professional racing, decided to turn his hand to team management. Muir began by running a team in the British Supersport Championship from 1999 to 2001 but then joined forces with Colin Appleyard Racing to run a team in the British Superbike Championship in 2005.

The team recruited Yamaha R6 Cup rider Kieran Clarke for their championship debut and with the backing of Hydrex they finished the season in 18th place. The Shaun Muir Racing (SMR) team returned the following season with Kieran Clarke and he was later joined by Steve Plater after he was left without a ride mid-season. Plater was able to give the team a 13th place in the overall standings and their first podium finish at Brands Hatch, whilst Clarke rounded out the season in 18th place.

In 2006 the SMR team secured Glen Richards as their number one rider and he was joined by Gary Mason. The team were on a high following Plater's podium at the end of the previous season, but neither Richards or Mason could follow up the podium result with although Mason came close at Donington Park with a fourth place. Richards' best result came with a fifth place at Brands Hatch and he ended the season in 10th, with Mason 17th in the final standings.

In 2007 the squad returned with the Hydrex backing and Karl Harris joined after a stint with HM Plant Honda.  'Bomber' put the team back on the podium after finishing second at Oulton Park and was regularly finishing in the top ten, securing eleventh.

In 2008 James Ellison returned to BSB after a stint in AMA with the team and immediately was scoring top ten finishes and finished on the podium at both Oulton Park rounds and also the penultimate race at Brands Hatch. Ellison was one of the most consistent riders of the year, only failing to finish three races, once at Silverstone and the two races he sat out of at Cadwell Park following a training injury. Guy Martin was the second rider in the team but a difficult season saw him finishing 18th overall whilst also competing at the major road race events onboard the Hydrex Bike Animal Honda.

For 2009 Harris makes his return to the Hydrex Honda team and is determined to pick up where Ellison left off, with 'Bomber' training harder than ever prior to the start of the new season. He is joined by former British Supersport champion Stuart Easton, who took the team to a win at the Macau GP at the end of 2008.
