Athena BSV DIO GP 50 25Kg Green Contrast Spring (Bore 50mm)

When you're tuning your scooter's transmission for a specific feel or performance goal, the contrast spring plays a key role. This Athena contrast spring, with a 25Kg rating and a green color code, is designed to work with Athena variators or as a direct replacement for your original spring.

The spring's resistance directly affects how your variator shifts gears. A stiffer spring, like this 25Kg model, will hold the variator in lower gear ratios for longer, which can improve acceleration off the line or help maintain power in certain riding conditions. Athena color-codes these springs to make it easy to identify their resistance, so you can select the right one to achieve your desired transmission setup. This particular spring has a 50mm bore, ensuring it fits correctly within compatible variator systems.
