WR250R Acerbis Spider Evolution Disc guard mounting adapters

Posted this over at TT and did not get a whole lot of response, so here is the info for those of you looking to install a full coverage disc guard on the WR250R. This will not fit the X as the disc is too big. I am looking for how many people would be interested in the adapter we are making to allow you to bolt this right on with no mods to the bike. Here is the info:

As we all know there is not allot 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 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 they are from the side:



Here is the Acerbis guard with the new center part we made:





Here is the disc guard bolted to the center section:





Here is the complete unit on the wheel before the front axle is installed:





Here is the gap between the disc and the guard:



And some pic of the guard on the bike:









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. 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.

Let me know if any of you have any interest in the adapter needed for this disc guard. If I can get a idea of how many we need to make we can start the ball rolling on this.

Did you ever get clarification from Firehawk if that WRF spacer fits? I recall some banter about it fitting or not.

Oh, lets just say he screwed his seal up pretty bad....

Oh shit...a bad case of... See, there is a reason why you have so much gas. Somehow that just didn't sound right....

Sorry, no, just too many different diameters between everything, no way to make the Acerbis smaller as the ID is too big...

Here is some more info:
Check out my first attempt at a web page...let me know what you guys think, I (hopefully) will add the PayPal link as soon as these are ready to begin shipping. I want to make sure everything is in order before any one sends any money.

If any one knows of a better way to create and host a web site, please feel free to let me know...sorry I am a complete noobie at this sort of thing.

Thanks again for all the interest and patience. I hope to be able to start shipping these first week of May.

New link at top of this post, thanks!

These are now ready for sale! Check out the website posted above for details. I was able to keep costs down and will be able to ship these for $15USD. Not sure how you folks up north in Canada and other countries will deal with import taxes, but if any one has some good ideas for how I should ship these to lessen the cost to you guys, please let me know. Thanks again for the patience and interest. You will be happy with the spacer. I have 24 ready to go, and can have more made very easy.

Website looks and works great Ivan! Love the pic with all those nice new shiny spacers all together.

Thanks! The guy who machined them is a God! Real high quality work. I think everyone is going to be real happy with them for sure.

I posted up the instructions here:
