De-modifying your bikes?

[Geordi La Forge]

I bought this game when it first came out on sale, it's been pretty good once you get on a roll and start buying upgrades and the like, but it's also it's downfall- everything becomes overpowered quickly, especially when going into multiplayer.

From what I'm seeing now, you can only play through the game once. There's no de-grading of your own bikes that would put you on a more level playing field, and there's only one career slot as well. I've put a few hours into it, and it can't already be done for good, can it? Or am I missing something?

De-modifying your bikes would be a great asset for multiplayer too, since people with lesser-modified bikes would get blown away, possibly adding in a modification screen before the race, allowing the rider to pick which parts to attach or not.

there's no point, like you said the bikes overpower quickly, so it takes very little time to get to the higher bikes, I got a full upgraded Lancer in like 8 hours total career time, so anyone else can do the same.
and honestly the first bike you get caps at 117 if I remember right, so that should be low enough to race anyone.
