ktm sx 380cc 2 stroke atv

[jakers388]

oh

[jakers388]

@martijnvdeen1983 did you have to counyer balance the motor or was it already counter balanced?

[Martijnvdveen1983]

@jakers388 no counter balanced. its a pretty small stroke so the vibs are not realy hard.

[AKBNY]

That thing is nasty

[SLEDHEADWFO]

sick bike

[cr85rmotocross1230]

is it harder to ride since u dont have the thumb throttle

[Martijnvdveen1983]

@cr85rmotocross1230 i have riddin 21 years dirtbikes so thats why i have the twist throttle . i like the more

[cr85rmotocross1230]

@Martijnvdveen1983 cool i love dirt bikes and ride a cr85r but it is a little to big for me but nothing can stop me from riding

[pateron125]

[seththompson917]

four wheelers with twisty throttles make me horny

[Kinkryder8]

[Martijnvdveen1983]

@Kinkryder8 yes it is a mx engine from a dirtbike and a stock chassis.

[devfuse]

@Martijnvdveen1983 is that a maybach? behind the alpha? nice quad !

[Martijnvdveen1983]

@devfuse haha no thats a lancia

[Kinkryder8]

@Martijnvdveen1983, nice! is it any faster than it was stock?

[Martijnvdveen1983]

@Kinkryder8 they are even

[tinmanrobby]

That's a killer quad, great build. See your other video, bet that 4-wheeler screams.

[Martijnvdveen1983]

@tinmanrobby if you turn the throttle wide open its a screamer

[Cobrazilla1]

Ziet er goed uit!

[Martijnvdveen1983]

@Cobrazilla1 dank u

[4sumfilms]

NICE BIKE BUDDY

[aejp99]

Good bike!!

[MultiFordpower]

@petexx5 thats a 2 stroke lol

[Martijnvdveen1983]

@petexx5 no its a 2 stroke i build it myself.

[dirtrider971]

@petexx5 are you dumb its a 2 stroke in a 505 or 450 chassis 

[dehulkrobbie]

@petexx5 can't you hear the difference between a two stroke and a 4 stroke?!

[Dillonmathieu12]

@petexx5 wow ur a dumb ass look at the bike even listen to the bike its a two stroke

[cda6542]

@petexx5 the plastics say 505 but its a ktm 380 motor

[blomfeldt88]

@petexx5 haha you fail it`s a 2 stroke!

[mrkillemall100]

@petexx5 You obviously dont know how to either be patient and watch the video, or know anything about bikes. Lol

[videoclip425]

@petexx5 Can you not hear the 2 stroke sound and see the 2 stroke pipe and header? you fail.

[fupaking123]

@petexx5 ur a fuckin idiot you can clearly see a huge expansion chamber let alone the sound

[85kid1]

@petexx5 can u not here the vid u dumb ass hahahah

[lakelinden11]

@petexx5 if you honestly think thats a 4 stroke you must be retarted and have no idea what your talking about, so just stop talking

[W1NDOWS7myIDEA]

@petexx5 Amazing.........making assumptions because of the sticker.

[thmike]

@petexx5 damn...i'm glad you can read what they come with..but know nothing about engines..you can see and hear that its got a 2 stroke motor...nice build martijn!

[ridedirt47]

@petexx5 its a two stroke where did u get a four stroke from man????

[Vince62965]

@petexx5 Their is sound differrence between a 4stroke and a 2 stroke and I can assure you this is definitily a 2 stroke :P

[Motomadman43]

@petexx5 What a know it all!!! He built it himself!!

[yellowyam125]

@petexx5 are you an actual retard?

[kingsofcorners]

@petexx5 2 stroke sound and you4 stroke lol

[pedroalextiago]

@petexx5 you dont have ears? this sound is a beautiful 2-stroke engine, and also you can see by the exhaust

[adrenalynejunky]

how the bike work? better than a original?

[robyz250]

Do you have the Engine Mounts fabricated ? I think you could sell them if you do. I would totally buy a KTM Quad and find a 380 somewhere and do this. However if you have that thing mounted solid and straight you should package your mounts and offer them for sale.

Are you deRailing your chain at all (chain coming off at all) ?

Is the airbox, carb, pretty water tight if you rode in a bit of water ?

I really want to race the GNCC series here in America with one of these !!!

[rodeofan5656]

howd you get a 2stroke to not smoke?! ive never seen that

[Martijnvdveen1983]

@rodeofan5656 the engine was hot when i start it. then a 2 stroke dont smoke

[MultiFordpower]

@rodeofan5656 lol be like me blow your banshee and blaster up thinking you mix em like a chainsaw 50:1 instead of 32:1 lol

[NoModzJustSkillz]

@rodeofan5656 its not because the engine wasnet hot its because of his fuel to oil ratio

[copsinmyhouse]

@rodeofan5656 Jetting and fuel mixture, with the perfect of the both they barely smoke

[TheChrisey]

@rodeofan5656 and also use a oil that has minimum smoke:)

[TheDirtbikeboyy]

@rodeofan5656 rev it alot my bike only smokes a bit

[deanpoopoo]

id love to shit haul that for a day!!

[spijker95]

@Martijnvdveen1983 Nederlands :) ?

[budubum]

nice.change that silencer coz it really limits the power of KTMs.

[WrathOfHades6661]

where do u live i have trailer to steal with

[Martijnvdveen1983]

@WrathOfHades6661 in a little town far far away ;)

[trac0808]

great job i am planning on doing a cr250 engine swap into a blaster

[Martijnvdveen1983]

@trac0808 great!!! bring back the 2 strokes!! brwaaaapp!

[BYRONHICKEY1]

@trac0808 i think a cr 250 would be a bit to big for a blaster maybe anything between 85-125 would be great

[trac0808]

@BYRONHICKEY1 no i am big boy i go fast with cr motor in blaster

[jkorn1000]

what engine work do you have done? plz reply back! thanks

[Martijnvdveen1983]

@jkorn1000 none. i have taken the 380cc sx engine from a dirtbike and fit it in. the engine is stock

[EMDSD90]

what the 2 stroke motor from?

[Martijnvdveen1983]

@EMDSD90 ktm sx 380cc dirtbike

[gibsonguy97]

@Martijnvdveen1983 could u make a video or tell me how did u get this motor to fit

[Martijnvdveen1983]

[chargerbaseball5]

[munkfunk123]

[Martijnvdveen1983]

[dirtbikehonda36]

[pbpaulieb]

[Dirtbiker4life99]

nice paint job on it is it custom?

[fmfraceing69]

[Augustwow]

Looks awesome dude :D

[paraquadmxer]

sick quad dude!

[codecracker33]

50$?

[atvriderman17]

what kind of engine?

[monsterrmann2244]

looks fast as fuck

[toargames]

Thats a 380 cc ktm engine of a motocrossbike

[GOTSTYKS95]

what engine is that? is it a ktm engine?

[XDPwnzorXD]

FUCKING AWESOME!

[487Zach]

that sounds great

[KTMrida4life]

Man that sounds really really good.. I need to get my bike sounding like that.

[Gamerforever1]

beautifull. 2 strokes for ever !

[farmfast]

Awesome bike, good job! Wish KTM would build one of these. I love my 450XC but this would be so much lighter.

[DutchCr125]

Netjes hoor!

[tjsdaname]

wow that turned out really nice!

[FMFYamaha05]

nice quad, and sounds great and i like the twist grip

[wAy2fStYFZ]

is this custom? im not into ktms so i dnt kno... i kinda want one lol

[Martijnvdveen1983]

@wAy2fStYFZ yes its custom built by me and my dad. i'm now going to race the second year on it with verry low maintenance cost.

[Proedge352]

@Martijnvdveen1983 because its a 2 stroke . i ride dirtbikes but nice quad . 2 strokes for life!

[mgpBLARG]

love it !!!!!!!!!!

[dangerouspowerG3sper]

What exahast do u have on it

[dangerouspowerG3sper]

What kind of exahst did u use. Did u use the stock ktm exhast or wat

[Martijnvdveen1983]

@dangerouspowerG3sper the exhaust is a one of a kind. special made in holland by dpr exhaust. a stock exhaust will not fit for a quad.

[verderider597]

love the quad but what happened to your fenders? i would hat to have loose rocks and shit flying up my face lol

[1991tommygun]

sick bike!

[rideskisallday]

lovin' it!

[rockstarrescue81]

so bad ass

[Kinkryder8]

that just the 525 chassis with a dirt bike motor? whatever it is it looks and sounds sick! glad its a 2 stroke. =]

[monkeybrains05]

How is the trans holding up with all the etra load on it.

[StraightUpScott]

sounds amazing! love the twist throtle to!

[Martijnvdveen1983]

thanks for all the nice comments

[wbc7705]

did you have to build brackets for the motor or did it bolt in the frame with out them?



[Martijnvdveen1983]

@wbc7705 i have made brackets that bolt on the originale frame mounts. no cutting en welding. i can stil place the 4 stroke engine in it if i want to but i love the 2 stroke sound en ride so thats not going to happen.

[wbc7705]

@Martijnvdveen1983 i love the sound too. and you have it almost the same sound as a trx 250r

[monkeybrains05]

how is the vibration with that motor not having a counter balance? I have a ktm 380 and i would love that motor in a quad for the dunes. very sweet, nice job!

[Martijnvdveen1983]

@monkeybrains05 the vibration is not that bad at all. its like a normal 2 stroke dirtbike.

[xXtrx250rXx]

ugly bike! go for a trx250r or a quadzilla 500 2stroke!!!

[Martijnvdveen1983]

@xXtrx250rXx opinion noticed

[MasterLoveBudd]

@xXtrx250rXx this is way better haha badass build man

[ThaFrody]

@xXtrx250rXx Shut your mouth, that bike is beautiful!

[xXtrx250rXx]

@ThaFrody thats just my opinion.

[BRAK54]

take that twist throttle off, other wise SICK quad

[Martijnvdveen1983]

@BRAK54 i have ridden dirtbikes for 20 years so i am used to have a twist trottle on my bike thats why i have one.

[Pimpwithalimp95]

that thing is sick take good care of it

[wheeler688]

fuckin nuts

[toargames]

@METALLIRATT a 380cc KTM 2stroke..

[deliciousjulien]

nice !!! veryyyyy nice !!! boaaaap

[snoopdivel1]

this bike is fucking amazing

[jojothedog1234]

can I suck you cock?

[savethetwostrokes14]

thats mad, but why didnt you just get a banshee? save the two strokes!

[mrkawi624]

@savethetwostrokes14 banshees arent exactly ment for racing more for the dunes

[Martijnvdveen1983]

@savethetwostrokes14 i wanted a quad for mx racing. the ktm is excellent for mx. the banshee is a awesome quad but not the best for mx. its a older design and heavier

[TerranMarineCore]

that thing is fucking SWEET nice job on the bike

[Avus95]

That is so BadAss!

I love the KTM quads, and this just takes it to a whole 'nother level!

[vitaliyr1]

what year is the frame?

[Martijnvdveen1983]

@vitaliyr1 its from 2009

[359CDH]

how the hell does a guy get ahold of 1 of these?

[Martijnvdveen1983]

@359CDH

build it your self like i did with this one

[938936029]

Great Job

[guninhatersdown]

2 strokes all the way

[Martijnvdveen1983]

thanks in the past if ridden dirtbikes so i'm used to have a twist trottle on my bike thats why i have one.

[hopkins189]

thats sweet, love the twist trottle

[Martijnvdveen1983]

well it will not be really slower than the 4 stroke configuration. its just different and i like the 2 stroke engine design. not to many moving parts.

its easy to work on and the 4 stroke cost to much to rebuild.

a zabel 700 will vibrate really hard. the stress on the frame/engine mounts will be big but it will be scary fast!

[beeqool]

@Martijnvdveen1983 very interesting thanks for reply :) i also like 2 strokes just because theyre different experience.

[beeqool]

ha ha why? is it faster now? very interesting anyway because i was fantasising too about puting a two stroke in one of these modern frames. allthough i was thinking about zabel 700 :)
