On a quick side note, Tony, you see in the pics how the shrouds have atleast an inch gap from sealing off to the radiator? And that's in the back of the RAD, not in the front. These shrouds are doing nothing other than looking good.

I don't recall mine having such a gap.

What length shocks do these arms require? How much were they from LS? Jon is a LS dealer. Maybe down the road we buy LS products that through him.

You aughta post your full review in the "Suspension" sub forum so its easier for people to find when they search for suspension related info. It also unclutters the lounge, which should be designed to discuss 'off topic' subjects that either don't involve the 250R or 250r related topics that don't have a specially dedicated sub-forum like "suspension" or "pics and vids".

I agree with you Meat, and I am planning on doing just that. Notice I said "Full Review coming soon, here are teaser pics for now."

Right on rablack, my OCD freaks out every time I see all these topics in the Lounge :friendly_wink:  Get that review written asap, I have some questions about those arms.

Here goes: Start of Full Review:

I will go through progress pics and installation before I got into further review of form fit and function.

Installation:
Level of Difficulty: mild to moderate

Comments: These are not much different to install than any other a-arms. The bushing mounts are very close tolerances though so they fit in the frame mounts rather tight.

Tips: A rubber mallet, a flat punch, and a hammer are very helpful for installation. The flat punch and hammer to open of the frame mounts slightly. The rubber mallet for gently persuasion.

Now onto the pics.

Style:
I think LSR did a great job updating the look of these a-arms. The upper arm looks the same as before, but the lower arm utilizes a cross blended 2-into-1 tube on the bottom. The upper arms use heim joints as before and do a great job at adjusting the caster to your preference. Paint also appeared well done. Notice in the pics, they also have an integrated design for the lower shock mount, which I really like. Smooth and sleek.

Technology:
Here is the slight bit of bad news. I am a little disappointed that LSR has not worked any of their advancement that they have in other model a-arms into the ones for our 250Rs, like the quick caster adjustment. I would have like to have seen that on these arms. The other things is they don't use the quick camber adjustments on these arms anymore either. I used to have a set of their +3+1 standard travel arms and they came with the quick camber adjustment. I found this very helpful. I feel these arms should have that as well.

Function:
To be determined. This installation is not yet complete, so they have not been tested in the field yet. This will come soon. I will be taking them out to the local mx track to test them along with my new custom axis long travel shocks. I realize that the shocks will make the most difference so I will try my best to stay objective to the arms or give feedback on how they work together.

ETC- If anyone has any questions, feel free to post them. Overall so far, I feel that LSR makes great products, including these arms, and I thank Jon (Spiritaces) for hooking me up with them. For those of you that don't know, Jon has recently become an Lonestar certified dealer. He is a great guy and will be getting plenty more of my business.

Looking good! It would help alot with atleast quick adjust camber. What length shocks do they use?

Yes, I miss the quick adjust camber. They use 19.25" shocks roughly.

Looking good. You might try to shift your resi's to the front or back of the frame rail to open up some air flow if you need it.

Thanks for the idea. I will take a look at that. It would be nice if I could get some rezzi clamps that would mount them in the front of the frame pillars.

Andy at Maul Tech Atv has piggy back clamps for Axis shocks. About the same thing as what Pep did. If they are about ready for service it would be a good time to do it,as it will require shorter hoses.

Yeah, I am keeping this in mind as it is not easy to find rezzi clamps for the frame anymore. I am not quite ready for a service though.

You will love those a arms.  I have those with fox floats and I couldn't ask for a better front end.

Just get yourself some piggybacks if possible. I applaud LSR for coming out with new products for a dying breed. Always liked the quality of my LSR stuff

If you can mount them shock ressies behind the radiator, like this

That's a cool setup Jamie, but  my hoses aren't long enough to do that.

Hey man how is the clearance on the tierod ends to the lower a-arm when you turn. Mine hit on my +2+1 Lsr arms. Can you post or text me some pics with them on and the bike turning please. 269-362-2458

Will do. I will get some pics tonight. Just curious, are both of your tie rod ends pointing toward the ground?

That's strange then, Jamie. My +3+1 ST LSR arms that I had on before these worked just fine with no contact. I did accidently bolt the tie rod ends onto the steering stem facing up the first time, and they would make contact. That was why I asked.

I don't like heim joints. Are there positive and negatives to them?
