Luke Hedger will join Tom Fisher and Kevin Van Leuven at G&S Racing Kawasaki to ride in the Superstock 1000 class at Thruxton.
After last-minute talks with team manager Mark Fisher, the 20-year-old was invited to ride for the team after leaving the British Supersport class.
Mark Fisher said: “I am building the bike for Luke as we speak and it will be ready for him by the time we get to Thruxton.
“It is a big step up for Luke in the middle of the season and a big ask for him to jump straight on for free practice with no previous time on the bike, but he is a very capable rider and is up for the challenge.
“There will be no pressure for him this weekend, all we want is for him to gel with the bike and get his confidence up.
“At the moment it is a one-off ride for Luke but depending on budget and his performance it could be that we will run him for the remainder of the season.
“I would like to welcome him to our team and look forward to seeing him at Thruxton.”
Tom Fisher added: “Both Kevin and myself are pleased to have Luke join the team.
“His input will help us with the development of the 2016 Kawasaki ZX10R.”
Hedger is a proven winner having taken the 2012 Monster Energy British Motostar Championship and Cup and the 2013 Pirelli National Superstock 600 championship.
He said: “I would like to thank Mark at G&S Racing Kawasaki for giving me this chance.
“It’s been a tough time for me these last few days and I am so pleased to be back in the paddock so quickly.
“I am looking forward to meeting the team and getting to grips with the 2016 ZX10R Kawasaki.”
Hedger will make his debut in free practice on Friday.
Two weeks ago Fisher and Van Leuven secured their best results of the current campaign with Van Leuven recording 10th place and Fisher 11th at Snetterton so they are hoping to replicate that at Thruxton on Sunday.
They have really got to grips with the new Kawasaki which is proving to be far more competitive than their opponents suggested and the results from Snetterton go a long way to proving this.
Thruxton is notorious to be a fast but bumpy circuit but both riders are up for the challenge as they head into the second half of the season.
The Superstock 1000 riders will take part in a free practice session on Friday at 11.50am prior to the first of two qualifying sessions on Saturday, the first at 9.30am followed by final qualifying at 5.20pm.
On Sunday they have a short warm-up at 8.55am to make final preparations for the 16-lap race at 2.15pm.
