When it comes to better handling and overall stability, the best things you can do is bolt-on Pro Circuits linkage system or linkage arm. Linkages are CNC-machined from billet aluminum and are incredibly strong. Each system or arm includes all of the required bearings and seals.
The pro circuit linkage does exactly what it's supposed to, settles the rear end down. I put this on my 2012 kx450f and it now keeps the rear tire planted on the ground in braking and acceleration bumps. Best part I've ever bought by far.
The owner before me didn't grease the suspension as needed and all of the stock grease is gone. My metal collar that went in between the bearing and bolt is rusted pretty bad and can't be reused. I'm wondering if this linkage arm comes with a new collar? Thanks in advance for any help!
This would only include the bearings and would required the use of the OEM Collars. You can find the OEM linkage collar for your bike listed here: http://www.motosport.com/dirtbike/oem-parts/KAWASAKI/2007/KX250F/REAR-SUSPENSION?sku=42036-0020
I could not find a specific rebuild kit for this so I contacted Pro Circuit and this is what they said:
"We recommend using OEM parts when replacing your bearings on the Pro Circuit Linkage Arm. Since Pro Circuit uses special tools to remove the existing bearings when replacing them, we recommend sending your linkage arm directly to Pro Circuit for replacement. Failure to use the proper tools when removing your existing bearings may result in damage to the linkage arm"

This Linkage Arm would use the same bearings as OEM. Since Pro Circuit uses special tools to remove the existing bearings when replacing them, they recommend sending your linkage arm directly to Pro Circuit for replacement. Failure to use the proper tools when removing your existing bearings may result in damage to the linkage arm.

The right link for a 2013 Ryan Dungey KTM 450 SXF?
Dear sir I am told the procircuit linkage arm # TPA113503.75 is the correct linkage arm for my bike is this correct the number is stamp onto the arm.
I just want to make sure before I order as I am in South Australia
Different length/design makes your shock compress and rebound better. It improves handling. Also good to consider anyway as most inner bearings on these stock pieces are toast after a year or two of hard riding. Most people don't notice because it happens gradually.
