These reed chamber covers for the Suzuki GSXR1000 replace the ugly stock caps. They are fully cnc-machined from 6061 aluminum and feature the "R" engraved in the top. Bolt holes are recessed so bolt heads are flush with the top of the cap. Kits come with both caps and four bright mounting bolts. The stock reed-valve assemble is used for sealing - no gaskets are necessary.
