[atc500x]

I have finally get my decal and complete the conversion!

[MonroeMike]

Sweet job, you do unique work.

That plastic looks like it belongs on there.

[3wheelmecca]

nice bike, I dig the semi-period correct plastic. I remember having those on my Suzuki TM400.

[pudge]

that is amazine. the drive shaft as a swing arm, did you have to build a gearbox for it on that rear tire. i love the sx's and really love that fat cat

[aldochina]

very cool toys there, that sx conversion has got to be a blast

[Brad200X]

Very cool. Kinda like an old BMW motorcycle.

[Russell 350X]

That is sweet! Never thought about someone doing that to a SX. That 70 is pretty awesome too.

[RapidRick]

That's awesome work. Have you road tested it?

[tri-shee]

Great looking bikes you have there . The 250es turned out great and i love the atc 70 with the track kit on it . Keep up the good work . I have all of the yamaha big wheels 80 ,200 , 350cc bikes and a 86 honda fatcat . Your conversion on both bikes look amesome .

[code200k]

LOOKS GOOD How does that drive ??? And how is the gearing ??? is it higher geared with the street bike rear end?? We have fat cats and big wheels they are differant to ride but are fun!!

[fabiodriven]

Great job man! That is bad-ass!

[ScottZJ]

Wow, that is just purely amazing! You have some made skills for sure bra! The SX and 70 together prove that alone.

[atc500x]

Thanks guy for your comments! I ride it a little bit every day just for fun,here there is about 1 feet of snow everywhere so I can ride in the field,and the pavement isn't the best for the moment with the studed tire.Gearing is a little bit faster,the SX ratio is 3.5 to 1, the rear end I use is 3.0 to 1.Anyway,I will not pull trailer with this one hehe.It's the first time I have a reverse on a 2 wheel bike hehe.I will take more video of it when I will have more place to ride. Thanks!

[harryredtrike]

absolutely beautiful,great job.

[Frankencelery]

That's fantastic! And reverse to boot!

[theiizz08]

[the great gazoo]

Wow! I KNEW somebody would do that to an SX, & you have done an incredible job! A frikkin' SX FatCat with REVERSE!! Nice work, bro. What kind of pipe is that?

[AngusJustice]

I agree with RiverRat post some vid's of both of them at play. Please!!!

[Brockey]

That truely is a sweet ride, well done. The fender work turned out awesome too!

[max]

Ive been on this site for a long time now. Those two bikes/trikes are the coolest thing ive seen on here in a while. Thanks for sharing!!!

[bigpimpin]

both are way cool!

[posty2100]

very nice work

[racer....X]

very nice!!

[vegas250rr]

I'm diggin both bikes! nice work

[atc500x]

Wow! I KNEW somebody would do that to an SX, & you have done an incredible job! A frikkin' SX FatCat with REVERSE!! Nice work, bro. What kind of pipe is that?


The pipe is a cobra,stock exhaust was too big to fit behind the side panel.But I will maybe try to find something a little bit more quiet.
A good thing about this swap is that you can convert any 250sx in about 30 minutes in a 2 wheel,drive shaft fit like the stock one,fender clip in the stock location....the only thing to remove is the battery rack,the brake cable is also the stock SX cable
I will take some video of those in action and let you know guys!

Thanks for all your comment

[drummer62161]

Very nice job, was this a kit? what rear set up did you use? I also love to fabricate and would love to take on a project like this, also what are the plastics off of??? and detailed pictures?

[atc500x]

It's not a kit,completly homemade.Differential and rear swingarm section are from a suzuki gs650 streetbike.The rear plstic are homemade,the section under the seat and the tool box are old 250sx fender,and the side panel are from a cr125 85 or 86 I think.Plastic welded and it's done.

[Mondexbrute]

Wow, that is too cool! Can't wait to see some video's of it in action!!!!

Sorry to bump an old thread, but this is just amazing!

Were the GS650 parts just remove from streetbike and drop onto the SX, or was there much cutting/welding/fabricating? This looks amazing and I want to do it.

[coolpool]

I'm impressed! I love the 70 also. What is the track kit from? a smowblower?

[cox]

Im curious to this as well^^^

dam nice work though on both machines....

[RiJiD-WILL]

VERRRRRY impressed looks like it is a totally bolt on kit.
I love the 250sx and now you can have the best of both worlds in 30min trike or 2 wheel whats your choice this is my next goal THANK YOU!!!!:beer:beer

[Dirtcrasher]

It isn't bolt on, he did quite a bit of fab work to get it right but is talented and too modest to admit it :D

Beautiful work done very well!!

[atc500x]

It's probably my BETTER trail bike for everyday riding,short wheel base do a very nice thing to ride in tight trail,and with the auto clutch and the reverse,it's a dream to ride.I have approx 350km done with it for the moment (hondaline speedo installed) without any problem,just kick and ride.Top speed of 100km/h (62 mph) with the suzuki gearbox.

[RiJiD-WILL]

Love the video that thing sounds like a monster!!

Atc500X what sortta welding did you have to do? it looks like just the shock mounts? I am really interested in converting one of my own...

[atc500x]

The exhaut is a cobra,I have modify the exhaust now,the cobra was loud,I removed the spark arrester and fit a stock SX spark arreter from a rusty exhaust.Now it's really quiet.Most of welds are TIG welded.Will take more picture tonight and will post it.

[atc500x]

I'm impressed! I love the 70 also. What is the track kit from? a smowblower?

Yes the track are from a snow bower,very funny machine to ride.I'm doing over 200km on it every winter to ride my dog... hehe

[tbr926]

yep need a post for the 70

[atc500x]

[TheRealFatShady]

I am still really impressed and would love to build one.

What parts came off the GS650G? Was it just the swingarm, differential, and driveshaft? Or 'final drive' (or is that another term for differential??).
Also what did you use for a rear tire/rim and axle?

And are those rear shocks off the 650 as well? Thanks a lot!!!

By the way, I looked at those threads and you did an amazing job on the fenders and tank/frame cleaning up. Did you just paint them? They look as good/better than factory!!

[atc500x]

Thanks for the comments,The final drive is from the gs650 and right and left section of the swingarm,I keep the SX part that goes to the frame and by chang they have the same diameter.The rear rim is from the SX,I cut 1 inch and weld it in the center to be able to center the wheel in the swingarm.The axle is a front axle from a 200es if I'm correct.The hub and backing plate are from a 250es.The drive shaft is a part of the gs650,and a part of the SX,Tire is 22x11-8.Shock are from a gs550e.Plastic are painted,the white section in the side panel are adhesive tape.The rear fender is a part of a broken 200es front fender.I built the complete bike,and after completly dismantle to sandblast everything
I'm very curious how much I could sell the whole setup on ebay,except for the upper shock mount,the swingarm and the seat/fender is a direct bolt on to any SX in 30 minutes.

[Bryan Raffa]

Nice JoB!!!!!! you did your homework !!!!! thats,,,,, a cool bike....

[TheRealFatShady]

Any plans for fitting a battery anywhere for electric start?

And when you cut 1", was that from the swingarm or around the center of rim? Looks like the middle piece of rim (from the GS650?) is welded there, and then I assume connected to the brake drum?

Looks real good. What type of paint did you use for tank/fenders, and did you clearcoat to make them shine?

[atc500x]

I have a battery under the seat to help light and indicators,I bought the sx with a bad starter and gear so I completly remove it to save weight,The battery could be installed in the trunk too.I cut 1 inch in the center of the rim,on the brake side to change the offset.The part welded to the rim that hold the spline for the final drive is a old sprocket,welded to the rim,and bolt the parts on it.The 250es hub is bolted in the stock holes of the SX rim.Paint is an enamel with 2 clear coat.Brake cable is the stock SX

[Jaketrimoto]

Awsome! Ive always wanted one of those! The rich kid down the street had one when I was a kid. He never let me ride it.

[RiJiD-WILL]

too cool thanks for all the details!!!

were you talking about selling the setup to convert any 250sx to two wheels or selling your convertible bike/trike25sx?

[TheRealFatShady]

Amazing job, I'm going to start gathering parts! Any plans for a 25" rear tire or sticking with the 22?

[miajosh]

love the 70 looks awesome

[atc500x]

Amazing job, I'm going to start gathering parts! Any plans for a 25" rear tire or sticking with the 22?
I would prefer the 22 ,25 will be too big,clearance problem with the inner fender

[donverv]

That SX is awesome I been trying to figure out how to do it with the drive shaft,did you use the swing arm from a honda shadow or something like that.

[atc500x]

front section of the swingarm is the stock SX,the rear is from the gs650,with the gearbox,drive shaft is also the same,250sx and gs650 welded

[Jason125m]

it was better as a trike =(

[atc500x]

don't be worry,I have not use a good running trike to do it.The rear end was destroyed,fender was broken,and engine was smoking

[TheRealFatShady]

You welded two driveshafts together? Any problems with it holding up so far?

[Jason125m]

Great work, that thing looks fun as hell.

[atc500x]

You welded two driveshafts together? Any problems with it holding up so far?

Yes they are welded,with a small sleeve pressed on both section of the shaft,tig welded.No probleme for the moment,I have over 200km done without any issue

[Shorty]

What snow make/model snow blower did those tracks come off of? And was there any major loss in speed?

[atc500x]

I think it was a canadiana,but other model use this setup.max speed is now 25km/h (17-18 mph)

[Auto_Demon]

I have finally get my decal and complete the conversion!

that 70 is awesome did u make that urself?

[200XMichigan]

Those are both awesome. The only problem is I can't decide which is cooler. Amazing work.

[atc500x]

that 70 is awesome did u make that urself?

Yes I did it myself
I will never have enought of my life to do all the project I have in my head!!! :)
