I would like to know how these compare. I have ridden old three wheelers, so are these strictly race machines.

 

250R no question & no they are not strictly race machines

 

The 250r is superior in my opinion also. You can do any kind of riding on either if you want. The great thing about the 250r also is that you can get parts anywhere.

 

Whoa there mule, that Tri-Z ain't shabby. That "no problem" is a little bit too much. I've ridden the Honda a lot and had a buddy with a Tri-Z, and they were both pretty amazing bikes. I like the double headlight on the Z and the 350X. These are great racers but can also be really fun trail bikes if they're stock/near stock.
