Genuine Royal Enfield Bush / Bushing for Bullet 350/500, Electra 4S, Machismo, Lightning | 112027/B

The Royal Enfield Bush (Bushing), Part No. 112027/B, is a genuine OEM bushing used on multiple older/retired Royal Enfield platforms. It’s cataloged simply as “BUSH”, and OEM fitment matters here because bushes are precision wear-parts: correct inner/outer sizing helps maintain alignment, reduces play, and prevents accelerated wear on shafts/bolts and mating brackets. 

This part is best replaced when you notice excess wobble, rattling, uneven movement, or oval wear in the joint where this bush is used (common in older mechanical assemblies). Genuine Royal Enfield bushes are made to factory tolerances—helping you avoid common aftermarket issues like loose fit, premature wear, or inconsistent dimensions. 

Because “bush” can exist in multiple locations on a motorcycle, the safest purchase method is to match the part number 112027/B from your old part/packaging or confirm using a parts diagram/microfiche for your exact model. This listing is restricted to confirmed models only (below) to reduce wrong orders and returns.
