When you see sportspeople excelling, you assume that their skills are pretty discipline-specific. You wouldn't expect to find Usain Bolt on the javelin field, while David Beckham is unlikely to have ever turned his hand at netball...
However, this apparently isn't the case in the motoring world, as Honda and Dunlop Tyres proved when they challenged TT rider John McGuinness and BTCC driver Gordon Shedden to a race upon their opponent's machine.
That's right. The two motoring legends – who both race a Honda – have each proved that they are more than dominant in their own division. Shedden is a double BTCC champion, while McGuinness is practically a veteran of his sport, with 23 TT wins under his belt.
But how would they fare in a swap? It was off to Scotland's Knockhill Circuit to find out.
The pair were both surprised by the other's ride, and just how different it was to their own.
Completing 30 laps in the Halfords Yuasa Racing Honda Civic Type R, McGuinness set a top lap time of 54 seconds. "It was brilliant; I didn't want to get out of the car to be honest," he commented after the race.
"The whole mindset changes when you swap from what you know to something new, and I was a bit nervous, but we're all racers and just want to go fast."
Meanwhile, Shedden, aboard the Honda CBR1000RR Fireblade SP, was just one tenth of a second slower.
