Honda CB750 Breather Cover - Finned CNC Billet Alloy Breather cover for Honda CB750 SOHC $75.00 Unfortunately this product is currently out of stock. Please contact us for more information. A breather cover for the Honda CB750 SOHC made from a solid piece of billet aluminium. This piece is CNC machined, meaning that it is much stronger, smoother, longer-lasting and (to some most importantly) shinier that inferiour cast aluminium replacements. The cover fits all SOHC CB750 and comes without fittings or a gasket. There's nothing worse than a clean bike with old, tainted, dented, scratched and worn covers. Why not refresh the lot with our breather cover, clutch cover, alternator cover and points cover.
