2005 Honda 450 r can you make it street legal in Texas?

get a texas lisence plate and put it on your atv

That will depend on the state but at the very least you will probably have to equip it with head and tail lights, break lights, license plate light, turn signals, seat belts, etc. Here is what is...

easiest way would be and exhaust and air box lid. The TRX's are way to restricted. If you get an exhaust make sure u have the jets adjusted

ya, make sure its got a spark arrestor in the pipe, and working turn signals and headlight and tail/breaklight :P oh and a mirror or two

20 km/h.
