Vehicle Information
Honda CBR250R Motorcycle - Street (2011-2020)
The Honda CBR250R, produced from 2011 to 2020, was a popular entry-level sportbike known for its single-cylinder engine and approachable performance. Throughout its production run in this period, the core engine specifications remained largely consistent. This model was powered by a 249.4 to 249.6 cc liquid-cooled, single-cylinder, DOHC engine. While the core engine platform remained consistent, cosmetic updates and enhancements were introduced. In 2015, some markets received a power increase and new bodywork with a twin headlamp cluster, inspired by the CBR300R. By 2018, full-LED headlights and new color options were introduced. An ABS version was a common option, and special editions like the Repsol, featuring MotoGP-inspired graphics, were available in select years.
