I'm sure there have been threads regarding this in the past for this bike.... I also wouldn't be surprised if many of the things listed below would also apply to the WR250, WR400, and the WR450. This is how I accomplished getting my bike street legal --- my way. I ride my 426 mainly in the Michigan woods and probably won't ever actually ride it to work. (though, a plate is a plate..... do what you wish with it - dirt, sumo, dualsport) Any money spent towards expensive stuff --- is just going to get scraped, crushed, or possibly destroyed doing single track. So, why not get it street legal the cheapest way possible. In Michigan, you can ride single track with an ORV sticker --- but, 2 tracks and snowmobile trails are off-limits. So, if you are ever in a situation where you need to get back to the trail head, you are risking getting a ticket by taking the quicker routes. If you have a plate.... the sky is the limit. The other variable to this thread is this..... This is what I did to make my WR426 street legal in Michigan. Your state will probably have different things that your state will be more picky about..... or maybe more relaxed on. I've also had friends simply call the local sheriff and ask for an inspection with even less things than I did.
