    I dug through www.kbb.com year by year. It appears there was a 300 EXC model in 2006 that was 2 stroke. 2007 it was called the XC. It will make a big difference to me.

    I've ridden the newer ones, and they're nice. But really, there isn't a big difference - just the price.

    I have an '07 300 XC-W. As the note before said, I believe the '06 was the last year in the USA that it was called an EXC. The 2-s EXC's were NOT street legal in the US! Only difference is the EXC came with lights. The XC-W (and XC's) will accept the lights "plug & play" - they are already wired for it and have the stator to support it.

    It depends on your state whether you can street register it. In NH its not a big deal for dualsporting them, fortunately for me. I need mine street plated for enduros and "turkey runs" (new england term for non-competitive enduro-type ride). I personally think it sucks on the road, but its awesome on the trails. 2-s don't like constant throttle riding (roads), and you can't "coast" them because they rely on the oil/gas mix to lube the top end of the engine. IMO, the 4-s EXC's are clearly better DS bikes, but I prefer the 300 for really nasty single track. It lugs lower than 4-s believe it or not, and as long as you use a tiny bit of throttle it will NOT stall (can't say that about 4-s). Do the mod's mentioned earlier (stiffer power valve spring, "softer" ignition map for '07+ bikes, and correct jetting) and throw a trials tire on it & you have an awesome technical terrain bike. One of the big reasons why some ppl shy away from this bike, is because if you make a mistake with the throttle in tight terrain it can get you in a world of hurt really fast. Those mods mentioned earlier, and a G2 throttle cam can make a big difference in controlling it in technical conditions.

    The '08+ bikes with electric start can have the e-start removed; I know a handful of racers who did that. It doesn't weigh much so you're not gaining much by doing that. You can also retrofit the '08+ bikes (250 & 300 only) that came without the e-start. Its a nice to have, but not nearly as important as it would be on a 4-s. The 300's are very reliable starter, with usually 1 firm full kick. No 4-s drill to learn either...

    It's a great bike but it's not a thumper.
    That middle pick is a 96 model i reckon.

    The 250's get rave reviews!

    For me, at #210+ geared up, extra dual-sport weight on the bike, and riding areas at 7K-13K elevations, the extra power of the 300 is welcome. And more commonly available around here on the used market.

    Don't ask me why it has 125 on the side of the bike and the properties of the picture state 125 as well but I know there is a 300 EXC-E start over there. I have seen an article somewhere with one delivered with signals, speedo and all the bells and whistles.

    I don't know either this or the 570 FE with the Motard lighting package would be my favored steed. I'd have to ride them both and then have the money to pay for them too.

    The difference without the e start is about 2kg. The 2007 250exc had an e option and that was the weight difference.

    Don't supersize or cut down on the lard sandwiches for a week and you will save that and still have the e start

    That pictures sure looks like a 125, what makes you think that it's not?


    To clear up the confusion, in Europe (at least most of it) KTM has only been selling the 300 in EXC form (before 2000 or so they were called EGS). We don't even get XC's and those other models. ALL the EXCs including the 125/200/250/300/380s 2- and the 250/400/450/520/525/530 4-strokes (maybe others as well) have been street legal since their introduction in the 1990s. They come with lights, reflectors, turn signals, speedo, license plate light/bracket and all the other crap legally required here. To pass the very strict EU emissions test, they are severely restricted from the factory. Quiet mufflers, very lean carb jetting, throttle stop, etc. They usually make about 7-11HP in stock form. :huh

    As an example, here is what KTM puts over the air filter of the 690RR to reduce power enough: A good old steel plate!

    Nothing other then the rest of the stuff on the page. That's part of the reason I went and posted the second picture I found.



    You lucky dogs, I'd take 7 to 11 horse power out the gate and put the wrench to the thing before ever putting a fuel mix in it. I'd be guessing this is about the norm over there. I'd almost trade off my 2001 640e for one but then I'd have to figure out how to get it over here too.

    Geeze let that poor 690 breath man!

    I weigh a buck fifty soakin wet, I could stand for a few lard sandwiches, okay hold the lard and throw some bacon on there, better be the good thick country style bacon!

    Thanks for the info. Lukas. I knew that all the 300's were 2-stroke's. I just couldn't figure-out the current or past "EXC" thing, in regard to the 300. I'm fairly new to this ORANGE thing. And, when KTM first grabbed my eye, all the EXC's (in the States) were street-legal (450 and 530). Furthermore, I knew that "factory" street-legal two-stroke's (at least here in the states) were definitely a thing of the past.

    When this "EXC" topic first came-up, on this thread, I kinda' suspected that it was the nomenclature for the 2-stroke, street-legal models offered in your neck of the woods. However, when I got on the KTM "international" site, I saw that "your" 300 EXC didn't have signals, mirrors, etc. And, I also noted that the KTM international site didn't catalog "our" XC and XC-W models. So, I looked at the specs., and just kinda' figured that your "EXC" was our "XC-W" (with a couple of minor differences).

    Thanks again for the clarification...

    Cool, e-start isn't worth half of 2kgs to me. I'd rather not have it, less to break and no battery to fuss with.


    The picture posted a few posts up is a 125 - you can tell by the shape of the cases, expansion chamber and cylinder (well, 125 or 150 anyway). The specs are for a 300 though.

    Great start to this thread and thanks everyone for their contributions - It seems like the only thing in the Thumpers section is big 4 strokes like KLR's. With so much interest in this bike, I hope we can keep this going -

    I think the biggest downside is going to be mixing oil while fueling up - I am planning on packing some small containers with enough oil to mix 1 or 2 gallons at a time - I hope it's not too much of a pain.

    How do these handle altitude changes - for example if you jet for 7500 feet and ride up to say 12,000 do they get running real ratty? Or do you notice it much? How is the mileage effected?

    Its not a big deal at all (unless you forget to do it!). I usually use the full syn Spectro, 100ml / gal... Easy to eyeball during fillups. I don't bother with a mix tank on a long ride - just turn off petcock (so the heavier oil doesn't drain thru before its blended), add the fuel & the needed amount of oil (1.5g? just add 150ml... easy) & rock the bike.
