It passed the Assembly a while back, and it was the Senate that postponed it. The article said that it MAY come up again next year.
The main argument against it had nothing to do with bikers' rights or anything like that; it was solely a question of cost of implementation.
Seems to me that if they wanted to get it passed without all the howling from those of us with modified exhausts, they would rewrite it to apply on a go-forward basis. That is, to apply to new bikes purchased after such and such a date, and exempt bikes already sold. Like ours!
But we'll see what happens next year. Some of these things just die on their own.
