They’re designed around a 320mm eye-to-eye length (12.6\") and suit a wide range of motorcycles when that measurement matches your frame. Built for durability and heat dissipation, the reservoir tank and alloy components help maintain consistent performance under load.\u003c\/p\u003e\n\n\u003ch3\u003eHow do these shocks change the way my bike handles?\u003c\/h3\u003e\n\u003cp\u003eThe shocks reduce transmission of road impacts through a nitrogen-damped piston and an external reservoir that increases oil volume and cooling. You’ll notice fewer small-vibration jolts and improved composure at moderate speeds, plus better response under heavier loads.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e320mm eye-to-eye fit for many 150–750cc bikes and scooters\u003c\/li\u003e\n  \u003cli\u003eNitrogen damping for controlled compression and rebound\u003c\/li\u003e\n  \u003cli\u003eCNC aluminum reservoir for larger fluid capacity and heat dissipation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eAre these adjustable so I can tune ride comfort?\u003c\/h3\u003e\n\u003cp\u003eYes — the spring preload is adjustable using basic tools so you can tailor sag and firmness to your weight and riding style.

Choose this if your motorcycle’s eye-to-eye length is 320mm and you want improved heat management, tunable preload and reliable materials for daily commuting, touring or modified builds. Not a fit if your bike requires a different eye-to-eye length or a model-specific mounting arrangement.\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: What measurement determines fitment for these shocks?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Match the 320mm eye-to-eye distance and check bolt diameter and clearance for fitment.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I adjust ride firmness without replacing springs?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes, the spring preload is tool-adjustable so you can tune firmness for weight and load.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"GZYF","offers":[{"title":"Default Title","offer_id":48082803884190,"sku":"B08SHXL7HM","price":118.98,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/gzyf-front-view-packaging.jpg?v=1785814899","url":"https:\/\/northtrailauto.ca\/products\/gzyf-12-6-320mm-universal-rear-air-shock-absorbers-for-honda-nitrogen-damped-adjustable-preload","provider":"North Trail Auto","version":"1.0","type":"link"}
