The Honda 500 twins are a series of straight-twin motorcycles made by Honda since 2013.
- CB500F standard/naked bike
- CB500X adventure touring bike
- CBR500R sport bike
- CMX500 Rebel bobber
These models are sold in Japan with smaller capacity 399 cc engines: CB400F (2013–2016), CB400X, and CBR400R. Their introduction coincided with new European licensing regulations establishing a mid-range class of motorcycles of limited power. The new 500 twins are similar to the earlier CB500 parallel-twins discontinued in 2003, but all-new from the ground up. They are made in Thailand, where Honda had previously made only smaller displacement motorcycles.
All models use the same 471 cc (28.7 cu in) 180° crank straight-twin engine with capacity and power below the A2 European driving licence limit. They share the same six-speed gearbox and the majority of cycle parts. The CB500X has a larger fuel tank and longer front suspension travel making it taller, and with more ground clearance.
On its release, the CBR500R was the one-design model the European Junior Cup in 2013 and 2014. Since 2014, Honda has partnered with local organisers to promote national CBR500R Cup events in Brazil and France; raced over various circuits, the competitions are open to amateurs from 13-years upwards.
