Both Samsung Suzuki British Superbike riders John Hopkins and Jon Kirkham are slated to ride at the upcoming Silverstone World Superbike round at the end of this month, giving the American a record of riding in BSB, MotoGP and WSB in one season.

The two riders are on the entry list revealed to bikesportnews.com today and will be the only ones from BSB to wildcard that weekend. Lee Costello and Keith Farmer are will race in the European Superstock 1000 class while Luke Stapleford enters World Supersport.

"This is a kind of busman's holiday. Taking a break from racing by going racing. But seriously, taking a one-off ride in the WSB series is a great way for our riders to further develop their bikes and practice some race craft without the pressures of the championship they're in – and at the same time giving the fans and sponsors an extra run-out," said team boss Jack Valentine.

"We've had good success in the past with wild card rides, too, like Tom Sykes' podium in 2008; we're not there just to make up the numbers. And we can bet Hopper will be out to make a statement or two! We're certainly looking to run competitively. Our only disadvantage is that we normally run under British superbike rules, which allows only one bike per rider, not two. That said, we've got one of the most professional teams in the sport, they're able to turn any job around very quickly and very accurately. We should be okay.

"This will be valuable track time at Silverstone for Hopper and will be excellent preparation for when we come back for the BSB Showdown round later this year – there's nothing like racing to get a real grip on how a bike's performing at a circuit. JK is needing some extra bike time, too. We've been working hard to find an optimum set-up for him and the WSB weekend will offer him plenty of good track time to improve his set-up. We're really looking forward to it, hopefully we can spring a surprise or two on the regulars."
