Wirth progressiv fork springs

There's no disputing the quality and functionality of motorcycle fork springs from Wirth. They've always been top-class. And they still are! Especially the current, polished version. Friction in the telescopic fork legs is virtually zero, so there's also no noise at all, even when you push them to the limit.

When you fit progressive springs from Wirth, your telescopic forks will at last be how you always wanted them to be: The fork is very responsive and becomes stiffer as the load exerted increases, It no longer dives when you brake, and gives you a perfectly smooth ride. Small bumps are smoothed out, and the fork handles hard impacts with ease.

Wirth fork springs are made of polished, surface-densified special steel. They're available for a wide range of motorcycles and tailor-made for each model.

• Better road contact and more comfortable response
• No more bottoming out, and less brake dive
• So you can forget about annoying rodeo rides like you used to get with your old, linear fork springs.
• And you no longer need any air assistance
• Easy DIY installation
• With type approval for Germany

Please note:
Contrary to possible vehicle manufacturer's specifications, Wirth fork springs require fork oils of viscosity SAE 10W.
Wirth recommends the use of fork oils with a viscosity of SAE 15W only for a few, explicitly named exceptions.
