Vis\u00e3o geral do produto<\/h2>\n
\n

O Corrente de motocicleta 420<\/strong> A corrente de transmiss\u00e3o 420 possui um passo de 12,700 mm e largura interna de 6,35 mm \u2014 a mais estreita e leve da fam\u00edlia de correntes com passo de 1\/2 polegada. Ela ocupa a extremidade mais leve do espectro de correntes padr\u00e3o para motocicletas, projetada para motores com pot\u00eancia moderada, onde a minimiza\u00e7\u00e3o da massa rotativa e do peso da corrente contribui significativamente para o desempenho geral da m\u00e1quina. Com 0,57 kg\/m e resist\u00eancia \u00e0 tra\u00e7\u00e3o de 15,6 kN, a 420 suporta a faixa de torque de motores de quatro tempos de 50 cc a aproximadamente 125 cc com folga confort\u00e1vel.<\/p>\n

\"Corrente<\/p>\n

A corrente de passo 420 \u00e9 padr\u00e3o na maioria das motonetas de 50cc, motocicletas de entrada de 125cc, muitas motos off-road de 50 a 110cc e uma grande variedade de quadriciclos e ve\u00edculos recreativos off-road menores. Seu baixo peso \u00e9 realmente ben\u00e9fico nessas m\u00e1quinas \u2014 uma corrente de passo 420 \u00e9 consideravelmente mais leve do que uma de passo 428 ou 520, e em uma m\u00e1quina de 70 kg com um motor de 4 kW, isso faz mais diferen\u00e7a do que em uma moto touring de 200 kg com um motor de 60 kW.<\/p>\n<\/div>\n

420 vs 428 vs 520 \u2014 Escolhendo o arremesso certo<\/h2>\n
\n

All three pitches belong to the 12.70 mm (1\/2 inch) pitch family but carry different inner widths and consequently different roller contact areas. The pitch number encodes both pitch (first two digits: “42” = 4\/8 inch \u00d7 10 = 12.7 mm; “52” = 5\/8 inch \u00d7 10 = 15.875 mm) and width class (last two digits). For bikes currently running a 420, attempting to fit a 428 or 520 requires sprocket replacement \u2014 the sprockets are not interchangeable between inner width families. Confirm your existing chain’s stamped number before ordering any replacement.<\/p>\n<\/div>\n

The 420’s narrower width versus the 428 (6.35 vs 7.85 mm inner) is the most significant physical difference between the two same-pitch options. Both use 12.70 mm pitch \u2014 and that’s the only dimension that matters for sprocket mesh \u2014 but the 420’s narrower roller means it will not seat correctly in a 428 sprocket’s tooth spacing. Always check whether your sprockets are stamped 420 or 428 before ordering, especially on bikes where previous owners may have upgraded the corrente de motocicleta<\/strong><\/a> sem substituir as engrenagens.<\/p>\n<\/div>\n

Vantagens e desvantagens do 420<\/h2>\n
\n

The 420 pitch occupies a clear niche. Understanding both what it does well and where its limits are helps ensure you’re choosing the right specification for your actual riding needs, not simply defaulting to a “bigger is better” upgrade that adds weight without benefit.<\/p>\n<\/div>\n
