Front Fork Spring 3.2 N/mm – 370 mm Dal Soggio – for Sphere New Heroes 65cc

The Dal Soggio 1P.KC03900 Front Fork Spring is a replacement or setup spring intended for compatible motorcycle front suspension systems.

This spring features a specified spring rate of 3.2 N/mm and an overall length of 370 mm, making it suitable where this exact combination of spring rate and length is required.

Fork spring rate is a key suspension parameter because it influences how the front end supports motorcycle and rider weight, reacts under braking, and uses the available suspension travel.

A 3.2 N/mm spring provides a defined resistance to compression and should be selected according to the suspension platform, rider weight, motorcycle setup, riding discipline, and desired chassis balance.

The 370 mm overall length is an equally important fitment parameter and should be matched precisely to the corresponding fork or cartridge configuration.

Because no verified public Dal Soggio documentation was found specifying the exact fork model, material, wire diameter, or motorcycle compatibility for SKU 1P.KC03900, installation should only be carried out where this spring rate and length are explicitly required.
