The build
Built in the garage, proven at Brands
August 2026
The last round on the Kawasaki done, it was time to start next year's project. Pro Fibre fairings arrived in August.
September 2026
A couple of months of hard work, late nights lock wiring, and help from MSS Performance getting the bike built up and ready for the track.
October 2026
First ride at Brands Hatch: everything worked, and on road suspension without pushing it was exactly one second off his ZX-6R lap time.
The one before
Kawasaki ZX-6RR
The bike that took two wins, a pole and nine podiums in Thunderbike Sport in 2026, before making way for the Aprilia.
