areas. The pitch number encodes both pitch (first two digits: &#8220;42&#8221; = 4\/8 inch \u00d7 10 = 12.7 mm; &#8220;52&#8221; = 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.

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=\"\u03b1\u03bb\u03c5\u03c3\u03af\u03b4\u03b1 \u03ba\u03b1\u03b9 \u03b3\u03c1\u03b1\u03bd\u03ac\u03b6\u03b9 \u03bc\u03bf\u03c4\u03bf\u03c3\u03b9\u03ba\u03bb\u03ad\u03c4\u03b1\u03c2 2\" src=\"https:\/\/motorcyclechain.top\/wp-content\/uploads\/2026\/04\/motorcycle-chain-and-sprocket-2.webp\" alt=\"\u03b1\u03bb\u03c5\u03c3\u03af\u03b4\u03b1 \u03ba\u03b1\u03b9 \u03b3\u03c1\u03b1\u03bd\u03ac\u03b6\u03b9 \u03bc\u03bf\u03c4\u03bf\u03c3\u03b9\u03ba\u03bb\u03ad\u03c4\u03b1\u03c2 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.
