Just switched from DK/JetBike/Slicks to Bowser/Pipeframe/Slicks. Quite a difference in drifting, acceleration and overall handling.
Will still take some time to get used to it, after 60+ Hours with the old combo. But I'm getting better, this was the first win in an online race. It was a good race, it even got exciting in the end, since I screwed up the last corner and then a blue shell was coming, as well as a thunderbolt. Luckily, I still got over the finish line :D
