Rantai ini menempati ujung paling ringan dari spektrum rantai sepeda motor standar, dirancang untuk mesin dengan output sedang dan di mana meminimalkan massa putar dan berat rantai benar-benar berkontribusi pada kinerja mesin secara keseluruhan. Dengan berat 0,57 kg\/m dan kekuatan tarik 15,6 kN, rantai 420 mampu menangani rentang torsi mesin empat tak 50cc hingga sekitar 125cc dengan nyaman.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-3589 aligncenter\" src=\"https:\/\/motorcyclechain.top\/wp-content\/uploads\/2026\/04\/420-Standard-Motorcycle-Chain-1-1.webp\" alt=\"420 Rantai Motor Standar 1 (1)\" width=\"600\" height=\"600\" srcset=\"https:\/\/motorcyclechain.top\/wp-content\/uploads\/2026\/04\/420-Standard-Motorcycle-Chain-1-1.webp 600w, https:\/\/motorcyclechain.top\/wp-content\/uploads\/2026\/04\/420-Standard-Motorcycle-Chain-1-1-480x480.webp 480w\" sizes=\"auto, (min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 600px, 100vw\" \/><\/p>\n<p>Rantai dengan ukuran 420 adalah perlengkapan standar pada sebagian besar moped 50cc, sepeda motor 125cc kelas pemula, banyak sepeda motor trail off-road di kelas 50\u2013110cc, dan berbagai macam ATV serta kendaraan off-road rekreasi yang lebih kecil.

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=\"rantai dan gir sepeda motor 2\" src=\"https:\/\/motorcyclechain.top\/wp-content\/uploads\/2026\/04\/motorcycle-chain-and-sprocket-2.webp\" alt=\"rantai dan gir sepeda motor 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;\">Pertanyaan yang Sering Diajukan<\/h2>\n<div style=\"font-size: clamp(14px,2vw + 10px,18px); line-height: 1.8;\">\n<p><strong>Bisakah saya menggunakan rantai 428 pada sepeda yang saat ini menggunakan rantai 420?<\/strong><br \/>\nTidak tanpa mengganti kedua gir. Gir 420 dan 428 memiliki jarak antar mata rantai yang sama yaitu 12,70 mm, sehingga mata rantai akan terpasang pada jarak yang sama \u2014 tetapi perbedaan lebar bagian dalam (6,35 mm vs 7,85 mm) berarti roller tidak akan terpasang dengan benar di celah gigi gir 420 jika rantai 428 dipasang. Rantai akan tersangkut atau bergerak tidak benar pada gigi, menyebabkan keausan cepat dan risiko keselamatan. Pasang rantai 428 hanya jika Anda juga mengganti kedua gir dengan komponen spesifikasi 428.<\/p>\n<p><strong>Apa perbedaan antara rantai 420 dan 415?<\/strong><br \/>\nSprocket 415 memiliki jarak antar gigi yang sama yaitu 12,70 mm tetapi lebar bagian dalamnya lebih sempit, sekitar 4,76 mm (dibandingkan 6,35 mm untuk sprocket 420). Sprocket 415 digunakan pada mesin dengan kapasitas sangat kecil \u2014 balap 50cc dan beberapa mini-bike \u2014 di mana berat rantai minimum menjadi prioritas. Sprocket 420 adalah pilihan yang lebih umum karena roller yang lebih lebar memberikan area kontak yang lebih besar pada gigi sprocket, mengurangi tingkat keausan gigi pada beban yang setara.<\/p>\n<p><strong>Bagaimana cara mengukur peregangan rantai 420 untuk menentukan kapan harus menggantinya?<\/strong><br \/>\nUkur 20 mata rantai berurutan (dari pusat pin ke pusat pin di sepanjang 20 mata rantai) dengan sedikit tegangan yang diberikan pada rantai. Jarak nominal 20 mata rantai adalah 20 \u00d7 12,70 = 254,0 mm. Ganti rantai ketika panjang yang diukur melebihi 261,6 mm (pemanjangan 3%). Tarik juga rantai menjauh dari sprocket belakang di tengah jalur rantai \u2014 jika Anda dapat memperlihatkan lebih dari setengah akar gigi, rantai sudah aus melebihi jangkauan penyetelan.<\/p>\n<p><strong>Apakah model 420 tersedia dalam versi O-ring tertutup rapat?<\/strong><br \/>\n4205-O (dengan segel O-ring, jarak antar gigi 12,70 mm, lebar bagian dalam 6,35 mm) adalah versi yang disegel. Produk ini menggunakan jarak antar gigi dan kompatibilitas sprocket yang sama dengan 420, tetapi dengan konstruksi bushing yang kokoh dan segel O-ring di setiap sambungan, memperpanjang interval pelumasan hingga 600\u20131.000 km dan memberikan masa pakai yang jauh lebih lama dalam kondisi basah atau off-road. Hubungi kami untuk konfirmasi ketersediaan dan detail spesifikasi.<\/p>\n<p><strong>Berapa banyak mata rantai yang biasanya dimiliki oleh rantai 420?<\/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;\">Ulasan Pelanggan<\/h2>\n<div style=\"font-size: clamp(14px,2vw + 10px,18px); line-height: 1.8;\">\n<p><strong>Park Jae-woo<\/strong>, Manajer Armada Skuter, Seoul (Februari 2025)<br \/>\n&#8220;We run 15 delivery scooters on 420 chains with a monthly replacement rotation.
