The Lino Tonti-designed double-overhead-camshaft engine has a six-speed gearbox and produces 72bhp at 10,000rpm.
The other machines in Sam’s trio are a 1925 Brough Superior SS100 Pendine Racer and a 1974 Talon MickMar five-speed trials bike designed by Michael Martin in 1973 before Talon Engineering took over the project.
