<p>The new clean design Nihilo Concepts Factory Chain adjuster Blocks are designed after the Factory adjusters. Nihilo went one step further making the trick Billet adjuster blocks light weight and super strong. These blocks are for the serious racer, they don't have adjuster marks etched on them because factory mechanics don't use them they always measure the blocks from the end of the swing arm to assure perfect alignment. The OEM axle threads into the left side adjuster block, Nihilo eliminated the triangle stand hole, I never saw a factory bike use a triangle stand. When a hole is left in the adjuster dirt and grime will fill the hollow axle and cause the nut to seize. The long side of the adjuster is longer than stock allowing the axle to be set up as far back as possible. Lengthening the bike is a good way to eliminate sketchy handling and is something most fast riders and factory mechanics try to do. By making the adjuster longer the adjusting bolt does not need to stick out of the swing arm as far giving it more strength and adjust-ability. You need to try these Factory adjusters to see for yourself just how trick they are.</p> <p> Fitment (<a href="https://cdn.shopify.com/s/files/1/0146/5899/4240/files/KTM_Husqvarna_Chain_Adjuster_Kit_20mm_Axle_-_Sheet1_1.pdf?v=1611593677" target="_blank">Don't See Bike below - See Full Fitment here</a>)</p> <p><span>20mm Axle</span></p> <ul> <li><span><meta charset="utf-8"> <strong>KTM Big Bike</strong></span></li> <li><span>2014 - 2022 KTM 250 EXC-F</span></li> <li><span>2014 - 2022 KTM 300 / 350 EXC-F</span></li> <li><span><meta charset="utf-8">2020 - 2022 KTM 150 EXC TPI</span></li> <li><span>2020 -2022 KTM 500 XCF-W</span></li> <li><span>2017 - 2022 450 EXC-F</span></li> </ul> <ul> <li><strong>Husqvarna Big Bike</strong></li> <li>2013 - 2022 Husqvarna FE 250 / 350</li> <li>2009 - 2022 Husqvarna FE 450</li> <li>2013 - 2022 Husqvarna FE 501</li> <li>2018 - 2022 Husqvarna TE 250i / TE 300i</li> </ul> <ul> <li><strong>GASGAS Big Bike</strong></li> <li>2022 GASGAS EC 250 / EC 300 / EC 350</li> <li>2022 GASGAS EX 300</li> <li>Actual anodized color may vary from image</li> </ul>
