Which of these quads is the quietist kfx400,z400,trx400,raptor 350 Also which is the fastest of them?

 

The kfx and the z are the same thing and they are probably the fastest because the trx is air cooled and the kfx and z are liquid cooled, which equals more power. The Raptor is the slowest of the bunch.

 

i imagine the ex and the z(kfx) are about the same noise level, the rappy will be the quitest as well as the slowest. The z has more power and top speed, but the ex will pull the front end up a lot easier because the front end is much lighter.

 

I've seen the trx400 and the Z race.They are neck and neck.

 

thanks. How much slower is the raptor 350.

 

the trx400 and z are not neck and neck, ive got a stock kfx and i beat a piped 400ex easily, i mean there neck and neck till 4th gear but once you start going faster the kfx and z pull away no problem.

 

Sorry KFX400JUMPIN I seen the two race and they raced through all the gears and they were still neck and neck.They were both stock.I had read where the z was faster but they were about the same.The z won a couple of races and the ex won a couple.Their both 400cc and about the same weight so you know one will not dominate the other.

 

There even til about 3rd-4th gear then the Z starts to pull away. The EX doesn't have much for topend compared to the Z. And the Raptor would be miles behind haha.
