The thickness of chain pieces of ordinary motorcycle chains is generally 1.5 to 2.0mm, while those with \u201cH\u201d (Heavy Duty reinforced) are thickened to 2.0 to 2.4mm. Is this 15% to 20% more expensive than the regular version worth it? It all depends on what car you play.
If you play cross-country and often encounter severe shocks, this money is definitely worth it. Thickened chain can increase the tensile strength of about 1200 pounds, which can save your 1 life and ensure that you will not suddenly break the chain when flying in mid-air. But if you only travel in the city, or ride a small displacement commute, you can honestly use ordinary chains-it saves the unsprung mass and avoids the chain scratching the engine box.
Many people have a misconception that if the chain piece is thickened, the life span can naturally double? Don\u2019t take it for granted, look at the following track measured data and you will understand that it is completely different.<\/p>\n\n\n\n

Don\u2019t guess, professional technicians are looking at \u201cC.C.W.\u201d this 3 indicator<\/h2>\n\n\n\n

Most motorcycle friends often only look at the price tag when buying chains. However, professional mechanics evaluated whether 1 thickened chain was \u201cmore powerful\u201d or \u201ca sharp weapon to destroy the car\u201d, looking at the C.C.W. matrix, that is, clearance (Clearance), strength (Capacity) and weight (Weight).<\/p>\n\n\n\n

Clearance: Maybe it will become a \u201cbox killer\u201d<\/h3>\n\n\n\n

The chain piece becomes thicker, which means that the pin shaft also has to be lengthened. The pin length of an ordinary 520 chain is about 17.5 to 18.5mm, but 520H directly exceeds 20.0mm. If you forcibly install 520H on a modern off-road vehicle with extremely compact space, the protruding magic buckle (chain cutting) pin will cut up your chain guide in minutes, and even directly scrape out cracks on the magnesium alloy engine case. Therefore, before placing an order for the \u201cH\u201d chain, remember to measure the margin between the front dental plate and the box with a caliper.<\/p>\n\n\n\n

Intensity: Violent Pulling vs Buddha Oil<\/h3>\n\n\n\n

The tensile strength determines how much destructive power the chain can carry before it breaks. An ordinary 428 chain can withstand about 4200 pounds of tension, while 428H can do more than 5000 pounds. Brothers who play cross-country often play clutch or fall to the ground with full throttle. The huge impact of this instant explosion cannot be carried without this extra strength. But if you usually give oil smoothly on the paved road, you can hardly touch the limit of the ordinary chain in your life.<\/p>\n\n\n\n

WEIGHT: A \u201cPARASITIC RESISTANCE\u201d DRAGGGLEGS\u201d<\/h3>\n\n\n\n

A chain of more than 100 sections, all replaced by thick bottom plates, rotating inertia and unsprung mass rub up. It is normal that the reinforced chain is 10% to 15% heavier than the normal version. If you install 428H on the 1 125cc scooter with low horsepower, you will simply find yourself unhappy-you will lose speed and acceleration performance in vain, and you will not get any practical benefits.<\/p>\n\n\n\n

415 vs. 415H: The tangle of fuel moped and mini racing<\/h2>\n\n\n\n

415 specifications (1\/2 inch pitch, 3\/16 inch roller width) are very popular in fuel bicycles, 66cc\/80cc two-stroke kit modified cars, and juvenile linear acceleration cars.
The engine torque of the modified fuel-assisted vehicle often explosively soars, and the ordinary 415 chain (only 1.2mm thick) as thin as paper is extremely easy to deform or even tear off. And 415H directly pulled the thickness to 1.5 to 1.7mm. As long as your engine is pushed to more than 3 horsepower, 415H is necessary to save your life, otherwise it is no joke to break the chain at 50 kilometers per hour. However, I have to remind the 1 sentence: 415H is relatively hard and has no fault tolerance rate, so your dental plate alignment accuracy and chain tension must be adjusted accurately.<\/p>\n\n\n\n

428 and 428H:Pit Bike (cross-country pit car) and how to choose an entry scooter?<\/h2>\n\n\n\n

By the time you reach a 428\u2011pitch chain (1\/2\u2011inch pitch, 5\/16\u2011inch roller width), it\u2019s essentially the domain of 100\u2013250 cc motorcycles.Brothers who play Pit Bike (such as deeply modified 110cc or 140cc pit cars) often fly slopes, so choosing ordinary 428 or 428H becomes the key. The inner and outer chain plates of ordinary 428 are 1.5mm, and 428H thickens the outer chain plate to 2.0mm. As long as you\u2019re heading off\u2011pavement and need a tough\u2011landings rig, the 428H is a must\u2011have. However, if you ride Yamaha YBR125 or Honda Grom (spring breeze baboon of the same grade) and walk in the city every day, the strength and absolute performance of ordinary 428 are excessive, and the lighter transmission system will make you ride more briskly.<\/p>\n\n\n\n

520 and 520H: Standard equipment for full-size off-road vehicles<\/h2>\n\n\n\n

520(5\/8 inch pitch, 1\/4 inch roller width) is the absolute \u201cpanacea\u201d specification in 250cc to 750cc off-road vehicles, Lindao endurance racing cars and street circles.
Buy 520 or 520H, all depends on your riding environment. For those who play Endurance (Enduro) or cross-country on the field, the transmission system is crawling in mud, gravel and extreme torque all the year round. 520H (chain plate thickness 2.2-2.4mm) can provide tensile strength of up to 8500 pounds, basically eliminating the tragedy of being thrown halfway to feed mosquitoes because of broken chains in deep mountains and forests.<\/p>\n\n\n\n
