Fork me!

Sometimes you just have to face that you wear out parts.  Anything that slides, rotates or moves will eventually wear.  This problem only gets worse when you face the face that a motorcycle nearing a decade old is going to have a diminished supply of low milage used parts on eBay.  I got mad at my forks for not sliding well and being very inconsistent.  The problem is that there is a nearly un-replaceable bushing in the outer tube and a very sketchy supply of “totally not bent” forks in the used market.  The advantage of racing superbike classes is that I am allowed non-factory replacement parts.  This led me to go down the path of Ohlins FGRT forks.  <img class="aligncenter size-large wp-image-3506" src="http://www.60dms.com/wp-content/uploads/2016/03/IMG_4201-1920×1440.jpg" alt="IMG_4201" width="700" height="525" srcset="https://www.60dms.com/wp-content/uploads/2016/03/IMG_4201-1920×1440.jpg 1920w, https://www.60dms.com/wp-content/uploads/2016/03/IMG_4201-400×300.jpg 400w, https://www.60dms buy levitra online with prescription.com/wp-content/uploads/2016/03/IMG_4201-768×576.jpg 768w, https://www.60dms.com/wp-content/uploads/2016/03/IMG_4201-1140×855.jpg 1140w, https://www.60dms.com/wp-content/uploads/2016/03/IMG_4201-552×414.jpg 552w” sizes=”(max-width: 700px) 100vw, 700px” />

At first this sounds like a easy way out albeit not a cheap one.  Well cost wise it was spendy, but easy it was not.  Ohlins does not make full forks for the 600 class bikes.  This is OK however they are larger in diameter and 15mm shorter than the forks I would be replacing.  The larger diameter was just a matter of calling Attack and ordering the correct diameter lower triple for a 2012 GSX-R1000.  The spacing and offset was the same as the set I already had.  This allowed me to reuse the upper triple and steering stem as well as the wheel, brake rotors and axle.  The FGRT forks had the ability to lengthen from a 120mm stroke to 130mm.  This would make up for some of the length difference however the gas-charged inserts I had in the stock forks also resulted in a 130mm stroke.  So this difference would have to be taken care of with extended fork caps.  IMG_3905

Of course I COULD have purchased a set and called it good.  However I had no answer that the correct ones even existed.  So the most logical solution was of course to make my own.  This stretched my skills in terms of duplicating exacting tolerances and both internal and external threads.  I am not able to not only match the previous fork length but move it up or down as needed.  It ended up being for more work than I expected.  However I have the satisfaction of a unique setup and one-off parts wether they actually make me faster or not.
