The 30-year-old Briton told the Daily Mirror: "When I was a kid I wanted to race motorbikes. When my dad bought me my first go-kart I actually wanted a motorbike.
"I'm not disappointed how things have turned out but bikes were my first love I suppose.
"I'd also love to test a MotoGP bike just to see what it's like. Naturally I'd know the lines but I'd love to know if I could even do it."
The Mercedes driver made similar comments after attending last year's Catalunya MotoGP, adding: "It's easy to be popped off a bike, though, so you couldn't take the risk during an F1 season. But I'll definitely try it one day."
