TBR (Trevor Birrell Racing) is an eleven time, group one national pro stock motorcycle champion. After more than a decade of developing the factory cylinder head, he needed to take his technology to the next level.

TBR in conjunction with BCH developed a new 4 Valve billet cylinder head to suit the Suzuki.

This four cylinder twin cam sixteen valve head is made of air craft quality 6061T for ultimate strength and rigidity.

This head was designed and engineered right here at BCH using our latest software and machining techniques.

    

BCH has all the requirments needed to produce custom designed billet cylinder heads for your engine configuration. We have the software, digitising, machinery, tooling & testing capabilities to produce the ultimate cylinder head.
