STOCK ROLLER WEIGHTS IN A STOCK BUGGY ARE 14G. OBVIOUSLY, RIDING STYLE, TERRAIN, RIDER WEIGHT, ENGINE MODS AND TIRE SIZE ARE ALL FACTORS THAT COME INTO PLAY WHEN TUNING THE TRANSMISSION/CLUTCHING ASPECTS OF YOUR BUGGY. TIME HAS PROVEN THAT THE MOST POPULAR SIZE WEIGHTS ARE BETWEEN 10-12G, BUT THERE IS NO FORMULA…….JUST PREFERENCE AND WHAT WORKS BEST FOR YOU.

DEPENDING ON AVAILABILITY THESE ROLLERS WILL BE SHIPPED AS HOCA OKO OR RDR TO ASSURE THE BEST QUALITY AND STOCKED FROM 9G TO 13.5G IN 1/2 GRAM INCREMENTS.

LESS THAN 9G IS INEFFECTIVE SO WE DO NOT STOCK LIGHTER THAN 9G.

Roller Weights size 18×14 for 150cc and 125cc GY6 4-stroke QMI152/157 QMJ152/157 engines.

We recommend starting performance upgrades by changing the variator roller weights first.

Heavier roller weights= A slower take off speed with more acceleration and a higher top speed.

Lighter roller weights = A faster take off speed with less acceleration and lower top speed.

Size: 18×14
