250 es big red vs. 250 sx

[flyingatc]

What are the mechanical differences between a 1985 250 big red and a 1985 250sx. I am trying to decide which one to purchase. They both have the same engines, driveshafts, transmission. The SX looks sporty, no racks. Are there any other differences mechanically?

[Hair Bear Bunch]

I think you'll find the SX diff ratio is higher, ie slightly faster.
Don't know beyond that.

[dougspcs]

They are both full suspension, shaft drive, electric start, reverse, oh yeah and awesome!!! Never mind what is different about them..truth is you should own both. Many here will agree..

I own both and still want another. So I watch the local CL and when I see one come up I'll get it. It will double your chances of finding the machine you want.

Once you own them both you can figure out what is different about them yourself!!!

It's fun to look at the orig sales brochures on the home page here.
They should list the specs.

The biggest difference for us is that 2 sx's fit in the truck.
Big reds look noticably bigger when parked next to each other but the
specs and wheelbase / stance numbers are not that much different.

IMO with some wheel spacers, they'd almost be the same
for farm chores.

The gearing may be different but the tires are also a different diameter.
and easier to change than gearing.

Can you get the search key to work?
This is a real popular topic.

Both is the best choice since they quit making them.
You'll see nice ones around 1,000 (give or take 2-300) and then, out of the blue, you'll
see one pop up with a flat tire, needs a battery, ripped seat but in great running shape
for a few hundred.

dougspcs has it right. I own both, and I like them for different reasons.

[userj8670]

I have both and as stated - each are unique. Essentially both are the same but serve diff. purposes. The sx is a work horse but geared more for fun. The big red is strickly business. However both are awesome trikes and I think that if you have the means, own both!

[Tippmann98]

I miss my old '85 sx. Looking to buy another one when a decent deal comes along. I also wanna get a Big Red and see what that's all about too!

[flyingatc]

Thanks. I own an 83 big red 200E, a an 84 70 and in the process of picking up an 85 SX. I am pickig up the SX because it has reverse and is shaft
driven. I guess you guys made the decision easy!!!!!!oh and a 250R remote controlled though...

Looks almost exactly like my house.
Same tractor and trikes but newer truck.

[1985BigRed250ES]

thanks man. yeah our tractor is an oldie but she has been good to us for the last 20 years we have owned her. the old truck is a 1966 chevy c10 short wide and it runs and drives. my dad is the 2nd owner of the truck and i am the 3rd lol. I will be restoring it in the future.

[1985BigRed250ES]

wait a min, you talkin about the John Deere in the pic or the Ford tractor in the pic?

[250sxatc]

get a sx i got a 85 and 5 or six big reds and wish it was the other way around but there preaty rare around here but yaui can do anything u want on ithers of thes but the sx makes evry thing that much more injoyable i love my sx feels a lil lighter and easer to throw around when trailprotrailpro driven it too

[Jason125m]

I can't believe people are still asking this question. There is a search feature, and google for a reason. This must be the 100000th thread on this topic.

^ Well, the board does get a bit boring at times........

The transmissions DO have different gears but overall you will merely notice the ES to be a bit slower, yet with more torque. It is more of a workhorse and hs limited front suspension. They also have completely different frames.

Both great machines, I just kept bending swingarms and my SX is now in the basement until I die.

[1985BigRed250ES]

dirtcrasher, why did the sx get put in the basement? just because of bending swingarms?

[Dirtcrasher]

^ With 2 - 350X's, 2 - 200X's a mill, lathe and all my tools, a choice had to be made until I can build a large steel building. Then maybe quit my job in time and fix bikes/trikes/quads on the side. Who knows.....

There's a few ATC70's down there too, I just don't have the room.

My "ambitions" in my high school yearbook was "Steve's Honda" but I doubt it will go that way exactly....

[Frankencelery]

Bending swingarms? Are you just a really big guy DC, or are you riding your SX like you stole it?

[Dirtcrasher]

^ I guess you haven't seen any pictures?

[1985BigRed250ES]

Dirtcrasher, i understand. i painted the gas tank on my 250sx today. it turned out ok lol. pretty soon i will need front and rear fenders

[CRAZY70MAN]

my 87 sx has a absolutely useless turning radius IMO. That is why they gave it reverse.:lol:......kiddin My 84 es will turn much tighter. As would a 250ES. Seems to be a bit shorter, more scrunched feeling than a big red also. Great other than that.......

[atc007]

Here's the info I found with the search button. All the answers you will probably ever need. If you don't wanna search. The Big Reds are a Much nicer machine,,unless you are gonna be riding it like a 200X,350x,or 250R. Good Luck !

Ok, that explains it, DC! That's about 4x the air I've ever caught on my SX.

[1984 honda 200s]

LMFAO awsome pic's DC ! Wish my 200s had full suspension for that purpose but till then i guess i'll be jumpin my 06 crf230
