 DR. PULLEY 16x13 (4.5 GRAMS) SLIDING ROLLER WEIGHTS 

FOR 50cc - 100cc 4-STROKE QMB139 ENGINES 

 

TRADITIONALLY, GEAR RATIO IS CHANGED BY THE UP-AND-DOWN ROLLING MOVEMENT OF THE ROLLER WEIGHTS IN THE RAMP OF THE MOVABLE DRIVE PULLEY (MDF)

 NOW THE INNOVATIVE DR. PULLEY SLIDING ROLLER WEIGHTS SLIDE UP-AND-DOWN THE RAMP TO CHANGE THE GEAR RATIO. THIS UNIQUE SLIDING MOVEMENT (NOT ROLLING) PROVIDES EXCLUSIVE ADVANTAGES TO INCREASE CVT PERFORMANCE. WITH DR. PULLEY, NO ABNORMAL WEAR WILL OCCUR EVEN WHEN RUNNING IN HIGH GEAR

 

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: 16X13  *  SET OF 6
LASTS LONGER THAN STANDARD ROLLER WEIGHTS
EXCELLENT HEAT RESISTANCE
LOW FRICTION / LOW WEAR

COLOR MAY VARY FROM FIRST PHOTO

EXAMPLE: 4.5g IS THE NEW BLACK PERAL
