But it doesn't deliver on performance. I bough this for my son's pw50 and it really does make it sound like a "real " dirtbike, but that's it.
I'm a honda/pro circuit guy, but on the PW50 there were no noticeable performance gains.
The OEM parts/equipment are designed to make the machines run at a standard rate. Be careful of buYing into the hype of aftermarket parts. While many do affect performance, many are gimmicks. This is a gimmicj.
