This trophy is for doing a wheelie for 8 seconds. I couldn't find any guides on the internet for any version, so I thought I'd make one for you guys. It's pretty simple:
1. Be in second gear at low-mid speed (but not stopped). You can press X/Square to lower your gear even in automatic transmission. You can see your gear next to your speedometer.
2. Hold down back.
3. Accelerate.
As you can see in the video, I don't even last 8 seconds though thanks to a bug with rewinding it still worked. If you don't want to worry about the rewind, just find a straight-away that lasts at least 8 seconds long. It's that easy!
