86' Big Red vs. 86' 250 SX

[Nick_n_ii]

What are the difference between the 2 trikes.

86' 250 Big Red...................................86' 250SX


:confused: :confused: :confused: :confused: :confused:

The big red had 25" tires. 250sx had 22's
The sx looked more sporty than the BR, but the BR is a real big utility.
I like the BR's better.
Im sure there is differances in suspension, but i';m not sure.
Im sure someone on here knows all the differances.

[Nick_n_ii]

Thanks for the input. I was able to see by some pics that the BR has less travel and the Forks on the SX look as if they have more travel. Was thinking of putingg the best of both togeather, Like a BR with SX suspention

[Tri-ZNate]

The SX is also faster due to the gearing in the rear end.

[jeswinehart]

the sx modles have a taller 5th gear giving them the edge in the higher speed area ,,, .

Did 86 BR's have hi low gear selection?

[Tri-ZNate]

I dont think so. They are the same engine as the SX

[Yamahauler]

Oh, so its just the diff that has differant gearing then?

[Tri-ZNate]

yeah the differencial has a higher gearing to give it more grunt on a big red.

I am thinking it's in the tranny ( from past post + a silly arse clymers manual ).

hey nick do you have any pics about your 250x and what condition it is in. I have an 86 250sx

[ScottZJ]

I have both an 86SX and a couple Big reds. The SX with racks would be a killer long trail rider. It has the nice sporty suspension to ride long distances and with racks you could carry stuff just like the Red. Now I love my big red cuz it has that low end torque and pulling power, It does feel alot more stable in some circumstances, due to its size and racks.
But all in all, I think the SX is the best all around trike out there, you have sporty fun and can even jump with them, but yet can still be a utility and work around the yard..............peace

You mean something similiar to this? BR with 200X front end:

[IrvSLedman]

damn, thats a nice looking BR lol. But i think he means the rear end suspension.

Still the question is, If I put SX forks and rear shock on a BR, other than top speed would that make the 2 equale on the trails?(note I have riden SX but never a BR)For say lonng 90 plus mile rides(Kalkaska trail loop in 90 miles north an d90 miles south plus many others in between)

[Tri-ZNate]

I say forget the SX rear shock and get a shock from worksperformance.com. Stock the SX rear shock travel sucks but is adequet if you only trail ride I guess.

I can honestly say that its like a night and day difference. If you can stand the price you'll love the ride.

[Somekindofjerk]

I like the look of the sx, and the fact that its a tractor anyway. What do you plan on doing anyway? for the casuall ride, if your a big guy of like camping, get the Big red, if you like to ride allot and want to go fast, get the sx!

In my opinion i like the sx!:w00t:

[cragster]

is my 86 200x faster than your sx mad max?

[Tri-ZNate]

Your X might be a little faster but not by much.

[Nick_n_ii]

I'm not a big guy, but plain to do the camping, fishing, trail rideing gig, Plus I'm building a 84' 200X for the fast times............Putting a powroll 198cc Eco. Kit in it plus much more. So the BR will spend its time doing the work and crusing the trails

[250sxrider]

Hey. I'm pretty shure that the shock on the BR and the SX are the same on the rear end but the swingarm is positioned lower on the sx to deliver more power to the pavement and so she can have more give in her suspension. Your front shock are totally different and you would have to do a fair bit of messing around and tinkering to get the sx shocks on the br. The sx forks are straight like on todays dirtbike. There alot longer and I'm not even shure if your frame, where the front end connects to it, would allow for the sx to fit at all. More than likly the bearings and all are different. Personally if you have to time and money go for it, but I believe that the BR should be left as is. Also your frame is different between the 2 bikes. They wouldn't be equal on the trail because the sx has more center-of-gravity and this is because the frame isn't as long, the wheel base is shortened and the frame isn't as wide.
Happy to lend a hand

e-amil me if you wants me to send ya some pics to show the difference in the 2.

I asked about putting SX suspension on my big red once and was advised it wasn;t worth it as the suspensions are nearly identical and the SX forks are not that much better.

I also could not find 5th gear in the tranny to be any different but the rear pinion is different and is a lower gear ratio to compensate for the 25 inch tires its almost an exact match to the big red when you factor in tire height and calculate axle ratio.

[bigredhead]

I'm told by someone who's had both apart that it's a " 1 tooth " difference in the rear end pinion gear .

heres the link with the gear ratios of both. if you plug the numbers into an axle ratio calculator used by jeep and mud truck guys the differences are consistent with what would need to be changed to keep the sx gearing the same for 25 inch tires.
