Honda CBR250 Parts for repair and restoration
Honda's 1986 CBR250 FOUR used a liquid-cooled DOHC four-cylinder engine. The 2011 CBR250R is a separate single-cylinder generation, so identify the year and full model designation before ordering service parts.
Engine oil filtration
The Honda oil filter replaces OEM 15412-413-005 and covers CBR250 applications for 1986–1994.
Sold individually. Match the full CBR250 model and confirm the reference against the filter removed from your engine.
Front master-cylinder repair
The front master-cylinder repair kit covers CBR250 2011–2013 and is sold as a kit.
Use it only for the front master cylinder; confirm the bore and seal style on the installed unit.
Rear master-cylinder repair
The rear master-cylinder repair kit covers CBR250 2011–2013 and replaces Honda OEM 43520-MB2-305.
It is sold as a kit. Confirm the rear-cylinder reference and bore before rebuilding.
Choosing parts for your Honda CBR250
Identify the generation first: Honda's archive describes the 1986 CBR250 FOUR as a four-cylinder model. Honda later used the CBR250R name for a single-cylinder model in 2011; these engines do not share a general parts range.
Match the exact application: the oil filter fits CBR250 1986–1994. The front and rear master-cylinder kits specify CBR250 2011–2013. Do not use one range to infer the other.
Check repair position and reference: the master-cylinder kits are specifically front or rear. Match OEM 15412-413-005 for the earlier filter or 43520-MB2-305 for the later rear kit to your original component.
