The Leyland Tiger, also known as the B43, was a mid-engined bus and coach chassis which was built between 1981 and 1993. This name had previously been used for a front-engined bus built between 1920s and 1950s. It replaced the Leyland Leopard, which had been in production for over 20 years. Leyland's then-competitor Volvo, having already won over many independent customers from Leyland with its successful B58, was at the time developing the B10M, which was set to further strengthen its position in the coach industry.
