Twinshock BITUBO WMB0 adjustable: spring preload red spring

Dedicated to Harley Davidson, Modern Classic, and Custom bikes, they have specific calibrations for each model, and are available in various color versions: "01" with the red spring for sportier applications, "02V2" totally black for more classic applications, and "03" totally chromed.

These shock absorbers improve the comfort and control of the vehicle while driving thanks to the internal hydraulic system. Linear or progressive springs are chosen depending on the type of vehicle application.
The continuously adjustable spring preload with a threaded ring nut (rather than with predetermined clicks) allows for finer calibration of the rear suspension on motorcycles used with just the rider, or with a passenger, or with a full load.

TECHNICAL FEATURES:

Single-chamber gas pressurized shock absorbers (Nitrogen), with floating piston oil/gas separator. Shock absorber body in high-strength alloy steel, heads in aluminum alloy machined from solid with CNC machining.

ADJUSTMENTS:

INCLUDED IN THE PACKAGE:

Application-specific assembly instructions, Suspension Manual, and wrenches for making adjustments.

POSSIBLE ACCESSORIES: For some "Old Style" motorcycle applications, upper and lower Spring Covers, or upper only, are available in black or chrome. Before purchasing, check that the space available for mounting the Spring Cover is sufficient to avoid any possible interference with the frame, or any bag attachments, chain guards, or other accessories on the motorcycle.
