As we all know there is not alot of options for front disc guards for the WR250R, I liked the way the Acerbis Spider Evolution front disc guard looked, but after some back and forth email with Acerbis, I confirmed that there was no disc guard made for the WR250R and that there were no plans to make any for this bike....bummer, same old story right? Wrong!

Here is what I did, I bought the adapter mount (Acerbis part#2043190059) that fits all modern YZF WRF 250/450 Yamaha dirt bikes, indeed this does not fit our bike as the front axle on a WR250R is a much smaller diameter than what must be used on those machines. The width is correct, but not the OD nor the ID. The Acerbis disc guard mounts to the bike by replacing the left side axle spacer using a machine specific adapter. Since the stock Acerbis mount has the bike specific part press fit in the center, I took it to work and talked it over with a CNC programmer/machinist friend. We both agreed that the center could be pressed out and a new WR250R specific part could then be turned and used instead. So figuring "what the heck" I went to the arbor press and sure enough out popped the center! Cool! I took the parts (stock WR250R left axle spacer, old Acerbis spacer and Acerbis disc mount) back to my friend and in about a weeks time, Viola! He had made the perfect adapter made out of aluminum, just like the Acerbis part! Here are some pics of the parts and how it looks installed on the bike:

Here are the four parts, the stock WR250R axle spacer, the new part my friend made, and the Stock Acerbis axle spacer and disc guard mount:

Here is the gap between the disc and the guard, looks good!:

I am using the WR250X front fork guards as I feel that they are better than the R quards as they do not flex as much, they also allow me to make my wheel swap to my X wheels easier. Now for the bad news: WR250X owners, this WILL NOT FIT YOUR MACHINE! The X disc is just too big! Want soem more good news? OK, here goes, you can shop around and buy this disc guard for around $28 for each piece or less, the outer unit is replacable in case of damage, you can choose your choice of colors for the outer disc guard, and my friend and I can make more adapters so we can all add this guard! We have to talk over the details for costs, so if there is enough interest from you guys, we should be able to make this happen! Let me know what questions you have and I will be glad to answer them as best as I can.

What do you guys think?

[D1EHARD]

Very Nice. :thumbsup: Love the look.

Wish it would fix the X, I'd be all over it.

[blueshopsuper]

What do you guys think?

What do I think? Why pay you to do something I could do myself on the lathe.:lol: Looks great! I won't be buying one but I will give you more gas. Good job.

I guess I need to spread gas around before giving you some more.

[Gargoyle]

What do you guys think?I think ... WOW! That's a pretty cool looking guard.

I am still not sure if adding a guard will help or hurt given the muddy, sticky, rooty, rocky conditions I usually find myself in here in the northeast.

So, I am on the fence for my bike ... but think that your setup looks first class!

[eljaye925]

Looks like a better design the the GYTR guard.

Just shop around online for the best price you can find for the Plastic disc guard in the color you like (there are many to choose from) and buy the center mount using the part number I posted up above, I will see if me friend at work can womp up (technical term) some more adapters and then you can get one from me and go from there...
:thumbsup:

[mwakey]

Very nice Sandman! You do good work.

Gas for your efforts....

edit: just found out I can't give you more gas. Little window pops up and says I need to "spread the love" before you get more from me. Sorry.

[vwsandman]

Very nice Sandman! You do good work.


Thanks! I always try to do things as OEM as possible....I like stuff that bolts on/bolts off with no modifications to the bike, plugs in to factory connectors, ect....I guess it is my form of OCD...

Takes longer/costs more, but IMHO a better quality product in the end....

[yoshie]

Thanks,just let me know when spacer will be ready,I will take one,
Thanks again

[yamahawk125]

ive had the white and blue on my bike for about five months i just dont know how to post picks to show everyone. i didnt have to make any different parts , mine just went right on with the adapter kit.

[vwsandman]

What adapter kit did you buy? It would seem the white and blue plastic is no longer in production...also I was told by Brian at Acerbis that there is no part they make that fits the 2008-09 WR250R and that they have no plans to make one. Maybe you used an adapter from a different brand like a Kawasaki or KTM? If you have the Acerbis part number that would be great, you can post your photos up to photo bucket or PM me an email address and I can post up your pictures...

[yamahawk125]

i really cant remember, i will have to look for the receipt but i think i ordered one for a wr250f and it went on perfectly with the kit, i will look for the sales slip and let you know. i like the black and blue you have it looks awesome.

[vwsandman]

Not to call you a liar, but according to the Acerbis site here: http://www.acerbis.com/p149_universal/185190.html there is only one adapter part number listed for any Yamaha dirt bikes, the #2043190059, which is what I ordered, I can assure all who are reading this post that this part will not work with out a different adapter...If you can find out what part number you used so we can verify one way or the other...That would be great!

here it is with the universal acerbis mount and guard

[vwsandman]

That looks good, so the adapter fit in to your wheel bearing seal and was the correct spacer and ID for the Axle? Do you have the Acerbis part number from the package or where you bought it from? Wish they still made the white ones....

Maybe take a picture of it off the bike for us please? Thanks!

[yamahawk125]

im still trying to find it , im almost positive i bought the universal mount and i think i bought it from motosport, but i will have to check, its been awhile, i think the black and blue looks sweet. i have a set of x wheels ithat im waiting to get tires for and the black would look awesome with them. when you swap wheels out do you have a oversized disc in front or are you using the r's disc? and what do you have in back, sprocket size? longer chain?

[vwsandman]

The X disc is too big for the Acerbis disc cover...that is what I have on my OEM X wheels. I have to swap brake calipers from the X to the R when I swap out my wheels. I am using a 47T rear sprocket for the R wheels, and the 43T from the R on the X wheels...I added two chain links from another chain I got from a friend who took off his OEM chain from his X for a new longer chain.

If you can post up some pics of your "universal" mount that would be great. Thanks!

[yamahawk125]

check out the wr250r phot gallery for more info on the disc guard.

[foeix]

DISC CVR SPI EVOMNT KT WR/YZ/F $32.95
Mfg. #: 20431900591820 Our #: T 736061 Vendor #: 73-6061
WR/YZ/YZF 02-05

This is the part Yamahawk said he bought.

[vwsandman]

Well there you go then, guess all any one needs to do is order the Acerbis part number 73-6061 and then order the colored plastic guard of your choice...no need to make any parts like I did...would have been nice to know this earlier...oh well as long as there is another option for us...I will let my guy at work know to not make any parts.....

[yamahawk125]

sorry dude , i hope i didnt screw you up with making a couple bucks

[vwsandman]

Oh no worries, I was going to offer them up cheap, I would have rather have just bought the one that fit from Acerbis rather than having to modify one, this is the cleaner way to do it..had to call in a few "I helped fix your VW" favors at work, ;) but it is all cool...saves me from having to fart around with selling/shipping/ect..I don't have the time...as I said, just glad there is a verified option for a full coverage disc guard for the WR250R...not much available for them other wise....Thanks for posting up your info!

[yoshie]

I have a question How does Acerbis part # 20431******and Tucker part#
73-6061 , so if Acerbis part does not work without adaptor so how can Tucker part work if it's the same part?

[vwsandman]

I hope this clears it up:

I bought the Acerbis Spider Evolution Front disc guard adapter #18208000 from Dennis Kirk, thier part number 616308..and from what I can tell that is Acerbis part #2043190059...starting to see a trend here? Trying to nail down an actual part number is pretty damn hard to do...

looks like yamahawk125 was able to order #20431900591820 and that part fit..I would assume that part number is an Acerbis part number...I will send them an email and see if I can nail down some specs and get a clear answer from them....it would be great to know the exact part number so we can just order this thing up....

I will let you guys know what I find out...

[yoshie]

Today I called Acerbis #2043190059 is the same for an wrr or wrf they both have the same axle .Also asked what are the last 4 numbers **1820**mean
Josh told me that they mean nothing.

[vwsandman]

to further confuse things, I looked at the package from my mount when I got home, the sticker on the back says that the mount I got fits Yam YZ 125/250 04-08, YZF 250/250 04-08 WR250/450F 04/08 WR 125/250 04-05, there is a part number (I think) 2043190059 on that yellow sticker and on the sticker on the front (from Dennis Kirk, I think) it says part # 61-6308, vend part# 05200085...so I have no idea what a "real" part number is...maybe I will get another email from Acerbis that will help explain all this....

Sorry this is such a mess, just want to make sure if anyone wants this that they get the right part and don't have to modify anything...

[yamahawk125]

sandman was right the inside and outside diameter are not correct on the guard mount, the one i used messed up the seal on the hub a bit. so if you want a acerbis guard you have to get the spacer mad by the sandman and friend. my mistake and how i didnt notice this is not good. i must have been high even though i dont smoke dope.

[vwsandman]

Guess it looks like I am back in business then! If any one is interested in this option, PM and we can go from there...I can get a count and we can have some made up for all...

[yoshie]

I just ordered mine from Yamaha today,just let know when you make one and the price.I'll take it. Thanks
