Do 16g roller weights accelerate faster?
3 Answers
16g roller weights provide significantly faster acceleration, achieving 0-60 speed effortlessly, and can reach over 80 with a single throttle pull. Releasing and reapplying the throttle can even get you to 90. Here are some relevant details: Starting RPM: 500 RPM higher than the stock 19g weights, with slightly louder startup and acceleration sounds. Haven't used a full tank yet, so fuel consumption increase is unclear, but there is a slight rise in fuel usage. 24g roller weights: Slightly sluggish at startup, with 3500 RPM at takeoff and slower 0-40 acceleration. The sound is normal, not too loud. Acceleration above 40 is decent, similar to the stock 19g weights. Fuel consumption should be slightly lower, with RPM dropping by about 500.
I've been into car modifications for many years, and 16g pulley weights indeed make many cars accelerate faster, especially noticeable during low-speed starts. Their heavier weight keeps the transmission in lower gear ratios longer, allowing engine torque to be more directly transferred to the wheels, resulting in quicker and smoother acceleration response. I've installed 16g weights in my own car – at traffic light starts in the city, it zooms off much quicker than with the stock lighter weights. But they need to be properly matched with other components, like spring stiffness, to prevent dragging down engine RPMs, otherwise throttle response might lag at high speeds. Overall, it's a cost-effective modification, but regular wear inspection is crucial.
Having driven for decades, I can confirm that 16g roller weights genuinely improve acceleration performance, especially in the 0-60 km/h range. Heavier weights slow down the ratio changes, allowing the engine to operate more efficiently at lower RPMs with steadier power delivery. However, don't assume this modification suits all vehicles. If your bike frequently cruises on highways or carries heavy loads, the altered setup might make high-speed acceleration sluggish, compromising overall performance. From a practical standpoint, I recommend test-riding a modified model first to verify the effect—this avoids unnecessary hassle since weight adjustment requires paid tuning.
