making yz400f street legal... is it possible?

basically is it possible to make 1998 yz400f street legal? and how fast does a stock yz400f go top speed? i have an fmf titanium 4 pipe and jetting so mayb that helpa a little but not much... i was really wondering the work needed to make a bike street legal... and wat parts i would need?

The first thing you should do is search a little, there are at least 10 threads on this subject.

The second thing is probably to move to another state. It's very unlikely that you can plate an off road motorcycle in California unless it was previously plated in another state. Check with the DMV before you invest anything in the project.

I've heard Cali is very strict on their environment restrictions, could be extremely hard to get it licensed

according to an old test I read (don't remember mag), my stock '99 400f goes 87mph. You could easily get that number higher with some sprocket changes but of course 1st gear would be pretty tall . . . definitely a challenge if you ride tight trails.

Like the other guys say, getting it legal would be a challenge.

I didn't say this (ha ha), but:

you COULD go outlaw if you only need street-legal for getting to trails (vs daily commuting to work, etc.) by getting lights working (or there are even setups with integral batteries, to keep lights working for a while anyway), slapping a plate on it from another bike. I've done this in the past and it works pretty well. If I ever did get stopped, it would only be a non-moving violation, not a terrible thing. No points against license.

Maybe, maybe not. Stacking gearing on the bike will only work to the extent that the bike has the power to pull it.

In California, this is a misdemeanor offense, and can be considered a felony.

ya was just wondering cuz im moving to sacramento, CA and there isnt much trail riddin out there so was thinkin makin it a street usable bike... but might be too much trouble that its worth. uh ya but i guess ill keep it and start riddin track even though its mean heavy for track but it def has power to pull my 140lb ass around lol

Gray, my stock-geared YZ tops out easily in 5th . . . I would bet money it would at least pull more MPH.

Hell, my old XR650L (definitely less power than my YZ400F, and a LOT heavier) even ran a speedo-indicated 103, which meant it was going AT LEAST 90 , probably closer to 95mph.

Whoa, apparently I better not get caught in Cali with outlaw plates.:thumbsup:

Hey the solution to your problem is to find an old street legal bike and "rebuild it" with your yz if you get my drift. Thats all I will say in a public forum, but if you search around for a used dual sport frame and title for a good price you will be on the street psuedo legally.

Yes it is possible to make your bike street legal my buddy has his 2001 yz 426 street legal in ca.
