This is what you think it is, it make a ton of power and rpm and makes my old 65cc kit feel like a stock bike. So far this seems to be a pretty durable top end and it makes alot of power. I am still tuning and all but it easily goes 50 and has a ton of torque. Make sure you get a 4 stud mp one case though
