Whats the differences between the different years of the trx 250R. I want t know any part thats different, no matter how smalll they are. I'm starting a 250R project quad and I dont want to buy anything that won't fit right. Also what years were they made I think it's 86-89, but I'm not shure.

I'm also looking for 250R parts, speecifically a frame, blown engine or one thats in pieces or need some parts you get the idea, cheap aftermarket shocks, and wiring parts.

Thanks for the help. :)

86-87 plastic was all white with blue nose and seat or red nose and seat!

88-90 was when they molded the light into the nose piece and you could get red plastic! keep in mind this is all recollecting 15 years ago!:D I had a 86 and I'm thinking it had a 6 speed (not for sure though) to this day I could kick myslef over selling that bike for all the wrong reasons:mad: :mad: :(

all liquid cooler r's were 6 speed. yeh, there are a good bit of differences between 86 and 89, nothing too major. mainly the swingarm, 1" forward frame on 88/89 and 87-89 had a longer rod, and 88/89 had shorter 5th and 6th gears, some other minor changes. In 88/89 the pegs mount like a 400ex.

was the swingarm shortened an inch, or was the frame moved forward an inch?

the swingarm is shorter and the frame is longer each by 1".

Macdizzy.com has helped alot, it had all the engine specs, but I could still use some help on the differences of the frame and other parts along those lines. Thanks for the info, it's really goin to help. :D

The 86 frame is generally a lb or two heavier I believe, and has stronger gussets than the 88.

www.rriders.com will have a lot of answers for you.

Go to Rriders.com they will help a lot.



Here are a few differences that have not been mentioned. If you are going with a lot of aftermarket parts very few of these differences will matter.


The 86 frame was heaviest, and strongest because it was some what gusseted from the factory, so it's the one to have

The frames were all the same length. Someone said 88-89 were longer, but they weren't

88-89 A arms are slightly wider, and slightly more forwards

engine mounts were slightly different, but any of the engines will work in any of the frames

86 had the longest rear shock
87 shortest rear shock
88-89 had the mid length rear shock
front shocks were all the same

86-87 headlight on stearing stem 88-89 on hood

To add to that, the dog bone/shock linkages were different lengths to compensate for the longer/shorter shocks.

ok ok ok i will type all the differences i have fired out over the years about the 250R and 250engine:

81-84 R engines were air cooled. in 83 they added a 6th gear. in 85 they added liquid cooling. 85-86 were a short rod rod engine with a shorter piston which made them rev higher but also had the tendency without a good port and matching pipe to have a 'flat spot' the gears in a 85 were taller and suited for desert/atc riding where a machine didnt need as much grunt.. 87-89 had the long rod which was a torquier mill had a bridged intake and exahust port. the airboxs on 86 were different with airtube from the engine came back into the airbox which 87-89 didnt have. the 86-87 air tube was a stright tube without the air bottle in there. the 88-89 utilized this and it helped smooth out the power a little and it also quieted it down. the 86-87 frame was the frame with the rear engine mount was also the swinger mount just like a dirtbike. the 88-89's had a tube striaght through which was a plus and a minus. that way you didnt have to worry about having your motor get stuck to the swinger but it put more stress on the back rails of the frame. the dome on a 85-86 head is more "milliable" it has more area to mill for better comrepssion. the ATC head gasket was also thinner for higher compression. you can change these out for different compression ratios. back onto the swingers- the 86-87 were a mild steel a little bit stronger than the frame. the 88-89 was a aluminum square tube design which was lighter but isnt as strong. the 88-89 was also 1 inch shorter to push the weight transfer more onto the front wheels which is why the 88-89 are a OEM +1 foward. if you go +2 foward on a 88-89 framed R you will really do a good number to your handling which is why i dont reccomend it. the 86-87 plastics were white and resembled the 250x/300ex with a hood on there and the head light on the handle bars. this plastic system had a shark scoop you might say underneath it that held the plastic as a brace and directed more air flow into the radiator. the 88-89 plastic is what the 400ex is deisgned after. it has one big headlight instead of the 2 400ex ones. but it is located in the same place. the wheel anodizing changed in 88-89 from gold to silver. also the a-arm and swinger colors changed from gold to silver too. the brake rotors are different also where the 86-87 had the 4 prong setup to the hub where the 88-89 used the modern 3 prong to the hub. also the front hub on the 88-89 was ligther than the 86-87 due to 2 reasons. it didnt have the webbing across the hubs and it only had 3 prongs. the rear shock linkage is complicated in this. i will continue in another post.

the 85-86 linkage is best suited for desert riding. it gives you mucho ground clearance but not the best ride. every year shock length was different in the rear. but you can use any length shock from any year as long as you have the matching year dogbone and it will be fine. the U shaped peice of the linkage is year universal. the 88-89 seat pan is 1 inch taller than 86-87 so most racers prefer a earlier seat pan. those are most i can think of off the top of my head. there are many many more than if i think about it i can tell you but thats it right now. anymore question just ask here!:)

That would make too much sense, and besides people don't even bother to use the search bottom, so how will they think of the faq? :grr:

Just for you guys whinning about people not using the search button, I was looking for an hour and found one post about this topic. This site has so much information on it that it can be hard to find what your looking for, and it's jus easyer to type up a new post. And putting this post in the faq section does make sense, if I knew how I would do that, If someone could put this in the faq section that would be good. Thank you to everyone that has responded to my question, it has helped tremendously. :)

I didn't mean my reply to you specifically, just the people that ask extremely obvious or repetitious questions which you couldn't avoid finding 5 pages of results if they simply looked.

you girls dont know all of them, there are even a lot of differences from 88-89, the radiator mounts are different, stock muffler mounts are different, front hubs are different, some of the internal engine parts are different, And bet you all cant guess what year had stock plastic heal guards?

I know what year had the heal gaurds stock, and you are right there is a good list of 88-89 differences, nothing major, just little things.
