Kamei Corvara S 390

The priciest and newest roof box on test is also from Kamei, and is a close rival to our winner.

Best price: £459.95

The priciest and newest roof box on test is also from Kamei, and is a close rival to our winner. The Corvara S is said to have “the fastest roof box mounting system”, provided you have channelled roof bars, and the T-bar-style clips slot in and lock down in seconds. At 16kg, it’s lighter and more manageable than the 510, and its dual-sided access is convenient for both fitting and packing. It’s been suggested this glossy black box holds more than its quoted 390 litres, but for fairness, we’ve compared them on official figures.
