Honda CB500 twins were a family of medium-sized standard motorcycles produced by Honda from 1993 until 2003. Because of their low cost, reliability, and good handling they were popular with commuters, and couriers.[1] They were also raced in the United Kingdom in the Honda CB500 Cup (changed its name in 2009 to the Thundersport 500 when Suzuki GS500 and Kawasaki ER-5 were included).[1]

The half-faired Honda CB500S was introduced in 1998. Production of the first CB500 twin range ceased in 2003 as the engines could not meet Euro 2 emission regulations.[1]

According to Honda engineers, the 499 cc parallel twin DOHC engine was designed to last for 300,000 km (190,000 miles). One motorcycle was tested by Moto Revue from 1993 through 1996. Dismantled at 50,000 km (31,000 miles), the engine was in perfect condition. At 100,000 km (62,000 miles) only the cam chain and the pistons were replaced, although, in the tester's opinion, it could have run with the original parts for longer with no problems.[2]
