MOTORCYCLE LAMP earns its ride

No pain, no gain! I was visiting my mate the other day and he just had a really cool machine in his living room. Of course, I was keen to go for a ride with him, but he said cheekily that I would have to earn it first. No problem for me, of course... At least I could prove my riding skills in advance and he got his money's worth, of course. I wonder if I earned the ride on his motorbike...?
