Double springs system for better bike stability. The kit also includes the hydro stop not installed in the stock fork. Furthermore, all the plastic stock parts are replaced with aluminum and nylon parts much more resistant than the OEM.

For those who prefer it, it’s still possible to keep the air system and install the kit without the springs (included in the kit), having an upgrade on the standard hydraulic system anyway.

For a great result, it’s also highly recommended the installation of Kit compression
