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=\"kadena ug sprocket sa motorsiklo 2\" src=\"https:\/\/motorcyclechain.top\/wp-content\/uploads\/2026\/04\/motorcycle-chain-and-sprocket-2.webp\" alt=\"kadena ug sprocket sa motorsiklo 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. Tooth tips that appear pointed or thinned, or leading tooth faces with a hook-shaped profile, mean the sprockets should be replaced simultaneously. Fitting a new 420 chain on worn sprockets will accelerate the new chain&#8217;s elongation rate considerably \u2014 the worn sprocket shifts load onto the chain&#8217;s side plates rather than the rollers, which is not how 420 chains are designed to carry load.<\/p>\n<\/div>\n<p><!-- \u2550\u2550\u2550 MANUFACTURER \u2550\u2550\u2550 --><\/p>\n<p>&nbsp;<\/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;\">Mga Kanunayng Gipangutana nga Pangutana<\/h2>\n<div style=\"font-size: clamp(14px,2vw + 10px,18px); line-height: 1.8;\">\n<p><strong>Mahimo ba nako gamiton ang 428 chain sa usa ka bisikleta nga karon naggamit og 420?<\/strong><br \/>\nDili kini mahimo kung dili ilisan ang duha ka sprocket. Ang 420 ug 428 parehas og 12.70 mm nga pitch, mao nga ang mga sumpay sa kadena parehas og gilay-on \u2014 apan ang kalainan sa gilapdon sa sulod (6.35 mm vs 7.85 mm) nagpasabot nga ang roller dili molingkod sa husto sa mga gintang sa ngipon sa 420 sprocket kung ang kadena nga 428 ang i-install. Ang kadena mahimong mogapos o mosakay sa dili husto sa ngipon, nga hinungdan sa paspas nga pagkaguba ug peligro sa kaluwasan. Mokabit lang sa kadena nga 428 kung imong ilisan usab ang duha ka sprocket og mga piyesa nga adunay espesipikasyon nga 428.<\/p>\n<p><strong>Unsa ang kalainan tali sa 420 ug 415 nga kadena?<\/strong><br \/>\nAng 415 adunay parehas nga 12.70 mm nga pitch apan mas pig-ot ang gilapdon sa sulod nga gibana-bana nga 4.76 mm (kumpara sa 6.35 mm para sa 420). Ang 415 gigamit sa mga makina nga gamay ra kaayo ang displacement \u2014 50cc racing ug pipila ka mini-bikes \u2014 diin ang minimum nga gibug-aton sa kadena ang prayoridad. Ang 420 mao ang mas komon nga kapilian tungod kay ang mas lapad nga roller naghatag og mas dako nga contact area sa ngipon sa sprocket, nga nagpamenos sa rate sa pagkaguba sa ngipon sa parehas nga mga karga.<\/p>\n<p><strong>Unsaon nako pagsukod ang stretch sa 420 chain aron mahibal-an kung kanus-a ilisan?<\/strong><br \/>\nSukda ang 20 ka sunod-sunod nga sumpay (gikan sa sentro sa pin ngadto sa sentro sa pin tabok sa 20 ka sumpay) ubos sa gamay nga tensyon nga gipadapat sa kadena. Ang nominal nga 20-link nga distansya kay 20 \u00d7 12.70 = 254.0 mm. Ilisi ang kadena kon ang nasukod nga gitas-on molapas sa 261.6 mm (3% elongation). Ibira usab ang kadena palayo sa likod nga sprocket sa sentro sa kadena \u2014 kon maladlad nimo ang sobra sa katunga sa gamot sa ngipon, ang kadena nadaot na lapas sa adjustment range.<\/p>\n<p><strong>Mabatonan ba ang 420 sa sealed O-ring nga bersyon?<\/strong><br \/>\nAng 4205-O (O-ring sealed, 12.70 mm pitch, 6.35 mm inner width) mao ang sealed equivalent. Parehas kini og pitch ug sprocket compatibility sa 420 apan adunay solid bushing construction ug O-ring seals sa matag joint, nga nagpalugway sa lubrication intervals ngadto sa 600\u20131,000 km ug naghatag og mas taas nga service life sa basa o off-road nga mga kondisyon. Kontaka kami aron kumpirmahon ang availability ug mga detalye sa espesipikasyon.<\/p>\n<p><strong>Pila ka sumpay ang kasagarang naa sa usa ka 420 nga kadena?<\/strong><br \/>\nLink count varies by machine \u2014 it depends on the rear wheel travel distance (distance from front to rear sprocket) and the sprocket tooth counts. 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;\">Mga Review sa Kustomer<\/h2>\n<div style=\"font-size: clamp(14px,2vw + 10px,18px); line-height: 1.8;\">\n<p><strong>Park Jae-woo<\/strong>, Tigdumala sa Scooter Fleet, Seoul (Pebrero 2025)<br \/>\n&#8220;We run 15 delivery scooters on 420 chains with a monthly replacement rotation.
