Honda CB500 twins are a family of medium sized standard motorcycles produced by Honda from 1993 onwards. Because of their low cost, reliability, and good handling they are popular with commuters, and couriers. They have the additional advantage that their engine power and cubic capacity meet the European driving licence A2 requirements making them ideal for riding schools and younger new riders progressing to a larger machine. They are also raced in the United Kingdom in the Honda CB500 Cup. The Suzuki GS500 and Kawasaki ER-5 are comparable motorcycles.

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. Honda announced a completely new global family of 500 cc twin motorcycles as a replacement in 2013, initially comprising three variants: CBR500R, CB500F, CB500X.

CB500 (1993 through 2003)[edit]

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.[1]

CB500 family (2013 onwards)[edit]

At the 2012 EICMA show in Milan, Honda announced a new global family of twin 500 cc motorcycles: CB500F (naked), CBR500R (sport- faring), CB500X (adventure-style)[3] The power output and cubic capacity meets the European driving licence A2 requirements, although Honda maintains the same power output for all markets.[4] ABS braking is available as an option on all three models. The CB500X has slightly longer front suspension travel and a slightly larger fuel tank. All the other differences between the models are in the riding position and bodywork.
