On a 420-equipped machine with 14 front teeth and 42 rear teeth, the ratio is 3.0:1, meaning the rear wheel turns once for every three crankshaft rotations at the engine&#8217;s output shaft (after the gearbox). Increasing the rear sprocket tooth count (or reducing front) raises the ratio, giving more acceleration at the cost of top speed. Reducing rear teeth (or adding front) lowers the ratio, raising top speed while reducing low-end pull.<\/p>\n<p>For the standard 420 specification, sprocket material is typically steel \u2014 providing the best durability match for a chain expected to cover 8,000\u201315,000 km before replacement. Aluminium sprockets on a 420 machine are uncommon because the weight saving relative to the machine&#8217;s overall mass is negligible, and steel outlasts aluminium by a significant factor at this chain pitch and power level.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-3479 aligncenter\" style=\"max-width: 100%; height: auto; display: block; margin: 12px 0; border-radius: 6px;\" title=\"re\u0165az a ozuben\u00e9 koleso na motocykel 2\" src=\"https:\/\/motorcyclechain.top\/wp-content\/uploads\/2026\/04\/motorcycle-chain-and-sprocket-2.webp\" alt=\"re\u0165az a ozuben\u00e9 koleso na motocykel 2\" width=\"1254\" height=\"1254\" srcset=\"https:\/\/motorcyclechain.top\/wp-content\/uploads\/2026\/04\/motorcycle-chain-and-sprocket-2.webp 1254w, https:\/\/motorcyclechain.top\/wp-content\/uploads\/2026\/04\/motorcycle-chain-and-sprocket-2-980x980.webp 980w, https:\/\/motorcyclechain.top\/wp-content\/uploads\/2026\/04\/motorcycle-chain-and-sprocket-2-480x480.webp 480w\" sizes=\"auto, (min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1254px, 100vw\" \/><\/p>\n<p>When replacing the chain, inspect both sprockets.

Common 420 link counts for 50\u2013125cc machines range from 96 to 120 links, but confirm the exact count from your owner&#8217;s manual or by counting the links on the removed chain. Ordering the wrong link count requires adding or removing links at the master link, which is possible but adds a step to the installation.<\/p>\n<\/div>\n<p><!-- \u2550\u2550\u2550 REVIEWS \u2550\u2550\u2550 --><\/p>\n<h2 style=\"font-size: clamp(18px,2.5vw + 11px,26px); color: #1a3c6e; border-left: 4px solid #e8a020; padding-left: 12px; margin-top: 40px; margin-bottom: 16px;\">Recenzie z\u00e1kazn\u00edkov<\/h2>\n<div style=\"font-size: clamp(14px,2vw + 10px,18px); line-height: 1.8;\">\n<p><strong>Park Jae-woo<\/strong>, Mana\u017e\u00e9r vozov\u00e9ho parku sk\u00fatrov, Soul (febru\u00e1r 2025)<br \/>\n&#8220;We run 15 delivery scooters on 420 chains with a monthly replacement rotation.
