415MX/420MX/428MX/520MX/525MX/530MX/630MX
For off-street application, chain ought to be promoted with upgraded metal alloy for all components, matter to going via distinctive warmth-treating process as nicely, to remarkably fortify its toughness towards rugged terrain driving.
YHK employs chromized pin and solid bushing into this chain to increase up its dress in stamina and shock absorption. Its exceptional functionality does aid inviting pleasure and excitement to bike owner even though likely extreme.
CAM CHAIN (Timing chain )
It is basically created for substantial speed working. Unique and sufficient heat-remedy generates harder hardness towards friction and excellent energy against exhaustion.
With coexisting capabilities of stretch resistance and lower sounds, this chain is substantially advisable for engine timing application.
SILENT CHAIN (Silent chain )
This collection is precisely fabricated with increased quality of alloy materials for engine timing application. With sophisticated stamping strategy on url plates and exceptional heat-therapy, it maximizes the speak to area with sprocket and largely decreases chain stretch because of outstanding friction and affect resistance. Of program, the operating sounds is significantly lowered at the same time. The built-in homes of YHK silent chain qualify alone as an ideal alternative for easy partaking system and least strength decline in electrical power transmission.
Steel Entrance SPROCKET
The raw material for the metal entrance sprocket is 20CrMnti.
Employing specialist gear hobbing and processing technology, to make the sprocket to be with higher precision and normal equipment, and with strictly top quality handle and exquisite packaging, to make our merchandise meet the quality normal of motorcycle business.
Metal REAR SPROCKET
The raw substance for the metal rear sprocket is C45.
By means of the particular forging procedure, to make the organization of the sprocket far more exactly, we can make different sprockets acc. to customer’s distinct demands.
ALUMINUM ALLOY WHEEL (sprocket for motorbike race)
The raw substance for the aluminum alloy wheel is 7075T6.
Its lightweight and resilient characteristics draw in the racer, especially for its unique and faddish physical appearance and useful design and style, meet far more substantial normal customers’ specifications.
