The Rocks put an unsettled week behind them with their second five-star performance at Walton Casuals inside 12 days.
Goals from Chris Breach, Terry Dodd, Stuart Axten, Jason Prior and Lewis Ide were the difference as the visitors came away with an excellent Ryman League triumph to put them second in the table.
It came less than a fortnight after they won by the same score at Walton in the league cup.
The Rocks edged a nervy first half by scoring in the 45th minute.
Breach was in the right place at the right time to power home a header from a Ben Johnson corner.
Up until then, Bognor had the better of the chances without managing to make them count.
Walton Casuals also had their opportunities and in the 40th minute Bognor goalkeeper Craig Stoner had to make a great save from a well-struck free-kick by Walton’s Richard Taylor.
Dodd scored in the 64th minute to make it 2-0.
Then on 71 minutes a great cross from Prior was met by Axten, whose powerful header found the net.
In the 79th minute, a great run through from Dodd saw him slip a through pass to Prior, who slotted the ball easily into the net to make it three.
The goal of the game came in the 87th minute when Ide powered a drive from fully 35 yards into the top corner of the net.
Bognor had topped off a much-improved second-half performance by scoring four in the half and outclassing the home side. They will also be very happy to have kept a clean sheet.
It qas a fine way to end a week in which they had dropped two points at home to Whitstable and seen Luke Nightingale retire and defender Matt Whitehead leave the club.
