    I have a 1993 DR350 (dirt model). There is no battery and the power available for "extras" is A/C. Forget charging anything (like a cell phone), running a GPS, or powering an electric tire pump. If those things are important to you, you'll want the "street" model that runs on D/C power.

    FWIW, I only rarely miss having a battery and the associated D/C capabilities. I fit a mechanical speedometer/odometer, carry a good small hand tire pump, and charging a cell phone or running a GPS can be accomplished with batteries or a wall charger in a motel each night. I like the simpler electrical system.

    The only thing I wish was better is the headlight/tail light. I'd like to run some of the very nice LED headlights that are currently available, but the vendors tell me they will not run properly on A/C power (I am not happy with the LED tail light I fit, either).

    It isn't often that I find myself stuck out in the dirt at night (not my idea of fun). But there are times each year when it happens. I think I may be stuck using a rechargeable LED light. We'll see...

    Regards,

    Gregory Bender

    Other than the electricals there are a few more differences between the dirt and the street versions.

    Dirt-pumper carb, stiffer valved shock w/ rebound dampening, Fork with rebound dampening (?), plastic non-DOT gas tank, al grab bar, nonDOT headlight with lighter cowl (strap mount), no horn, 70watt stator, no passenger peg or mount, solid foot peg mount, no speedo just odo, non-cush drive rear hub, no steering lock, no helmet lock, non vac petcock, No carbon can (cali).

    Anything else guys?

    In some states (Cali) you can not plate a dirt model DR. Even if it was once plated when you tranfer the title (sale) they will not let you register it for street use.

    False. I have bought and sold many plated dirt model bikes in CA.

    Other than that, you pretty much nailed it on the head.

    It's pretty simple to rig up a rectifier using inexpensive off-the-shelf components (a full wave bridge and a capacitor) from Radio Shack. You get DC but still have only 70 watts tho.

    So, nuts and bolts from those that have the trail version....

    would I go wrong in selecting the trail, all things considered. I have a DL650 for the nicety things....I think I will be good with the trail version...

    I had a WR400 that I had converted and didn't have a battery either....I still kick myself for selling that one!

    Recently? The stop plating dirt bikes in Ca in 2004. I guess if you have a plated dirt bike which was done pre04 they will still allow it.

    Dirt model has rim locks and came with non-DOT knobbies. They do not have brake light switches or wiring Nor do they have screw mount points for mirrors on the brake or clutch perch. As delivered the dirt model has much lower final drive gearing. '98 and '99 "S" models got upgraded suspension like the dirt models.

    Tell me more! :>

    Got a link to a how to site?

    NC will ticket a motorcycle with "Not for Highway Use" or the like on the MSO even if the bike is legally plated in another state. If you're stopped there, they run the VIN thru the in-car computer. Apparently that information is in the vehicle record.

    Upgraded dirt suspesnion as the same rear shock for all year and the 97+ dirt fork.

    Also
    Dirt-No clutch or sidestand saftey both of which are DOT requirements.

    There might be better descriptions elsewhere... search for full wave rectifier

    These components will suffice...

    The completed rectifier will look something like this:

    FYI, A full wave bridge delivers a slightly higher DC voltage that the AC supply voltage (RMS voltage) so the output of this setup on a dirt model DR350 will likely be around 17VDC with a theoretical maximum current of about 4 amps.

    I just purchased new Mefo Sport Explorer Tires for my 1990 Suzuki DR350S Dualsport. For the rear tire, 120/80-18 they said to use a Bikemaster tube 3.75/4.00/4.25-18 TR6 tube, Part # 370187. The dealer said that tube was 1 size smaller ( he didn't have the next larger size ) and would work just fine. Is he correct? Thanks, Frank

    i wouldn't have guessed that the SE stator puts out 200 watts, when looking at baja design's website it looked to me like they were claiming 90 watts http://www.bajadesigns.com/tech-info/stator-reference-chart (i might be reading all of this wrong)

    The FSM list a SE as putting out a max of 125W at 5K RPM. No listing for Max output on the kick start "S". Though I suspect it is the same since the stators look the same.

    I would assume the BajaD website you link is giving arrpoximate Wattage for a dirt version, as those guys typically deal with street legalizing non street legal bikes.

    I think the Baja Designs unit is intended to upgrade the 70 watt single phase offroad model. I'm not sure about the exact output of the "S" model stator but would have to be close to 200 watts. Mine runs all the OEM lights plus an electric vest and heated grips and still maintains 14 volts at anything over about 2500 rpms. I don't run a battery so at idle the lights dim when the turn signals cycle but at riding speeds no problems.

    Just thinking about total wattage. Headlight - 60, taillight - 5, miscellaneous - maybe 10, heated grips - 35, electric vest - 55. In truth I've never run the vest on maximum output but it's a cycling controller so when it's on, it's on. So, that's 165 watts. Don't know how much more capacity remains but at riding speeds, it will hold 13.5-14 volts with all that stuff on.

    I have a '99 dirt model converted to street legal. I'm running the stock AC electrical system - no battery. It runs a Vapor speedo and all the necessary components to be street legal; high & low beam headlight, turn signals, tail light, brake light, plate light, horn. I also wired in a Powerlet outlet to run heated gloves and it works well. I almost never ride at night so I run a 35w headlight to save power. At idle it just barely generates enough power to run things, but it works. I've occasionally thought about getting a street version, but for my purposes I like the dirt model - it's simple and weighs about 30 lbs less than the street model.

    Here's mine

    thanks for the info, i've been wondering about this and not finding good info. i had an 8" race light on my XR650R and loved it, so did my riding buddies at night, i'll probably put some kind of brighter light on my SE.

    Out the 1993 trail dr350. All was pretty well....not a garage queen, until I noticed a glistening around the front left set of cylinder fins. Appears some oil is "weeping"..aka leaking from around the front left bolt/seam by the oil vertical oil hose....looks like the base of the head -

    Maybe a dumb question....would that most likely be the head gasket?
