    A front disk brake would be nice - a tachometer would be WONDERFUL. Alas it works fine the way it is.

    Skid Plate:
    When I get into a corner and need an obsolete / hard to find item, I go to ebay and ask everyone that has dimantled parts for sale from the same bike, "I need (what ever part...) would you have one for sale?". Everyone, without fail, will answere the question. One out of 15 will say yes and asks a low price. Everyone Wins!

    This is what you are looking for: NX 150 - Made in Brazil.. it shares almost everthing with your nx 125 except for the cylinder and the rear fender stuff..

    Well, the NX 150 is a great bike, really good for what it is and has very low fuel consumption, mine did 35Km per litre at 90Km/h of the speedo.. (And my Tornado does around 25Km/l at 100Km/h of the speedo).

    The real problems it has is that it is an old bike right now, you can find spares here in Argentina, but not all of them...
    Personally, I would buy a XR 200L or XL 200, that have the same engine of the NX 200, more suspension and the most important thing, you can get newer bikes..

    Really, the bike was great, it made me really happy, my problem was buying an old bike and thinking that I could just start it and ride.. It needed a lot of work, but at last it was great...

    The bike is ready to ride. Starts up and idles great!

    The rack arrived from Germany and was painted dark blue to match the handlebars, seat, and fork gators.

    Still need the front sprocket cover after searching and searching. It will be a long term quest.

    The kick stand sank deep into the packed snow and required a wooden snow shoe to keep the bike upright.

    The only mods were the shortened Suzuki SV650 rear shock, an inch of preload fork spring spacers, and that SWEET looking ADV sticker.

    Hi, very interesting reading this thread and as a newcomer I would like to say hello, and :wink: I have just bought me one o they NX125 transcitys here in Spain and although it is ok, I am already thinking it would love me to put a beefier engine in! I have spent all day researching this little thumper and it seems to be a pain fr info/parts. I have found most suppliers but sod all on how to improve the little darling.

    Is it the same basically as the XLR 125? can a NX150 barrel and head be simply bolted on? lots of not so sure info about when what I need is: "This is a fact" info.

    any genuine and helpful comments on how to add a little to this essentially crackin machine, gratefully appreciated.

    @Honda Scoot: Your NX is a JD09. That's the only model the US got.

    @Jan: You don't want one of the original equipment NX skid plates. They're flimsy, thin sheet metal and are only good for stopping small stones that are thrown off the front tire. You will need to make one yourself.

    Have a closer look at Honda Scoot's picture.

    [​IMG]

    The front bolt goes thru the skid plate and into the frame. There are two bolts, at the rear of the plate that also bolt into the frame. I used a piece of aluminum diamond plate to fabricate a skid plate for my old 1986 TLR200 (Reflex) trials bike. The three bolt arrangement was very similar to the the NX's. I bent the plate around a 3 inch or 4 inch piece of pipe and then bent a small tab for the front bolt. I then had a friend weld small pieces to strengthen the bend. From the right side, the bent piece of aluminum looked like a "J" rotated clock-wise 90º (I hope this makes sense). Don't worry about making something that "hugs" the engine case. Just make something that's strong enough to absorb hits from big rocks and tree trunks. If necessary, a skid plate is disposable, your engine case is not.

    Here's a nice image of the TLR200's skid plate. You can see it's very similar:

    [​IMG]

    And, a parts fiche image of the way the TLR200 skid plate bolts to the TLR frame (sorry it's so big).

    Hey guys. Just found this thread and thought i'd say hello

    i'm 20 and have been commuting daily for 3 summers now on my 1991 NX 125. It's been a good first bike for me so far. I was disappointed at first only being able to go 60mph on the bike, but now i know its only 13hp(and i'm 6ft 200lbs), im impressed. I average about 72mpg, mostly driving in 5th with the throttle pinned

    Heres a pic!

    Welcome Kazer

    We are the same size, but I was 30 when your bike was new. :rofl
    Mine also gets wide open throttle quite often with some great back road exploring.

    Thanks Scoot! I saw a couple posts back a member asking about engines with similar pistons as the 125, Has anyone confirmed this? My dad is completely against me selling the bike(as am i) but i wouldn't mind tossing a hundred or two at this thing for rejetting the carb and maybe a .30 or .60 bore for a little more "umph"

    1991? Really? I thought the NX125 only made it into the US from 1988-90 only. That said, your color scheme is totally different from what I've seen in the past (and damn cool to boot).

    I know that "pinned in fifth gear" feeling. :D

    I'm not 100% on the year, but i will take a picture of the stamped plate on the frame and post it. The bike is in storage currently though. Also, I don't know the history of the bike and whether the color scheme is factory or not but i certainly do like it!

    It sure looks factory based on the way the decals are applied. Either that or a previous owner was very meticulous with designing and applying them to the bike. Your VIN should include a 'JD09' somewhere, which is the model designator. Perhaps that's a decal set from an overseas model?

    Or, from a NX250? Hmmm.... :hmmmmm

    EDIT: Yep, I was poking around in the NX250 thread and those are NX250 graphics. Of all of the NX250 graphics, I think those are the only ones that do not designate the bike's displacement as part of the fairing decal. The "250" can be found on the side covers (which appear to have been omitted from your NX).

    That sure is interesting! I wonder why someone wouldve have gon through the trouble to make the bike appear to be a 250 :fpalm. Unless the bike was damaged and somebody had all of the fairings from a 250.

    I'll confirm the year and vin next time i see the bike. Any chance that it's a 250? :evil

    Decal sets are hard to find. Probably just used what was available to finish a paint job? Looks better than my "Plain Jane" white '88.

    EDIT: The seat and gator are lighter in color and match the decals. The mystery continues!

    No, you have an NX125. Nice try though. :D

    An NX250 is water cooled and has a 19" front wheel and 16" rear wheel. It's even more street-oriented than the NX125 and NX650 are. The bodywork is different and won't swap over. The headlight fairing is different, too. It doesn't have the two slots under the light. Your NX actually has more in common with the NX650 and TransAlp than the NX250.

    The only thing that comes to mind, about the decals, is either the p.o. liked the look, had them on-hand or were free/cheap (or a combination thereof).
