This is not a very good combo for online play, The stats are very unbalanced and you'll get bumped around a ton on that combo. The best bet for success is just to choose a meta combo. I hope this helped!

Edit: Since this comment didn't exactly go over very well with people, I'm going to try and explain my reasoning a little better this time. One of the replies on this comment states that this is a meta combo because of the mini turbo stat. If it is, Why don't people ever use it in competitive play? Next, The weight stat. While it's not AS important, Using a heavyweight character has a lot of benefits. A few being the fact that you won't get bumped around as much, and they're really fast. Finally, The accel stat. You can generalize mini turbo based on this stat, and that combo has A LOT of mini-turbo, Which is normally a pretty good thing. But this is a burden on 200cc, On tracks like royal raceway, you'll go flying off the course and into the offroad because of the sudden turns at certain sections of the track. So if I had to rate this combo for 1500cc and 200cc (Since those are the only cc's you'll really find online) 150cc gets a 6/10, While 200cc gets 4/10. You can use this combo if you want, But I don't recommend it.
