Abstract
A front fork for a vehicle comprises a telescopic fork leg having an outer tube and an inner tube telescopically arranged relative each other. A main piston arrangement in the inner tube regulates a damping fluid for damping movements between two parts of the vehicle. The telescopic fork leg comprises a pressurizing piston arranged in the inner tube and configured to pressurize the damping fluid. The pressurizing piston comprises an axial first end portion facing the main piston arrangement an axial opposite second end portion facing a pressurized volume. A fluid reservoir for holding a pressurized fluid is fluidly coupled to the pressurized volume. The pressurizing piston is coaxially arranged with the main piston arrangement, inside the inner tube. The fluid reservoir is at least partly arranged on an outside of the inner tube. Also, a front fork and a vehicle having fork legs according to above are described.
