buying-2-discount-300pxl-.png● YUMINASHI GT4S / GT4R ALUMINIUM 4V ROCKER ARM SET(MSX/GROM 125 - Z125 MONKEY - CT 125 - WAVE125...) (14430-KYZ-904S)

● These light weight 4-Valve aluminium rocker arms are the stock rocker arms which come with the YUMINASHI entree GT4S (21/18mm valves) and GT4R (22/19) 4-valve heads.

● These aluminium rocker arms can be used as a replacement for the YUMINASHI, KOSO, TAKEGAWA aluminium rockers, and as a replacement for the steel 4-valve rocker arms which you can see with Chinese and Thailand 4-Valve cylinder heads.

● This set comes complete with 4 tappet adjusting screws and nuts, and the total weight is 110 gram (3.88014 Ounces) which is 43.88% lighter compared to the steel rocker arm set with a weight of 196 grams (6.9137 Ounces).


● BENEFITS OF ALUMINIUM ROCKER ARMS:

Reduced Weight:
Aluminum is significantly lighter than steel, decreasing the overall mass of the reciprocating parts in the valvetrain.

Improved Engine Response:
Lighter valvetrain components allow the engine to rev up faster, improving throttle response and overall performance.

Lower Risk of Valve Float:
By reducing inertia, aluminum rockers can help prevent valve float (valves staying open too long at high RPMs).

Reduced Noise:
The lighter weight and reduced inertia of aluminum rockers can contribute to a quieter valvetrain.
