Each shim is forged from durable 4140 steel and laser-etched with its thickness for fast identification during routine maintenance or a race-weekend service. The set covers sizes from 1.72 mm up to 2.60 mm and includes three pieces at every step for spare options and repeated adjustments.\u003c\/p\u003e\n\n\u003ch3\u003eWhich KTM models will these shims fit?\u003c\/h3\u003e\n\u003cp\u003eThe Hot Cams HCSHIM00 kit was selected to match the shim-under-bucket valve systems used on many KTM 250, 350, 450 and 500 four-stroke bikes produced between 2005 and 2017.

Motorcycle mechanics, private racers and owners of KTM four-stroke dirt bikes from the covered model years who perform shim-under-bucket valve maintenance will benefit most. If you regularly service valve clearance on KTM 250–500 four-stroke models listed for 2005–2017, this set removes the need to source individual shims and speeds up precise clearance setting. For riders who prefer professional shop service, bringing this complete set to your mechanic ensures the correct shims are on hand for accurate, single-visit valve adjustments.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Do these shims fit my KTM model?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: They fit many KTM 250–500 four-stroke models from 2005–2017 listed in product specs; verify your engine uses shim-under-bucket design first.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I stack shims if I need non-standard thickness?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes — the kit provides three shims per size to allow stacking, giving additional combined thickness options when required.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"Hot Cams","offers":[{"title":"Default Title","offer_id":48084138262686,"sku":"B003CKVIG0","price":96.74,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/hot-cams-shim-kit-front-packaging_5c504397-3d60-45fe-ba28-01da8eaa65c3.jpg?v=1785847230","url":"https:\/\/northtrailauto.ca\/products\/hot-cams-8-90mm-complete-shim-kit-hcshim00-for-ktm-2005-2017-0-04mm-steps-4140-steel","provider":"North Trail Auto","version":"1.0","type":"link"}
