About the SKF Seal

The unusual green colour comes from the patented material SKF uses for these seals. It combines lasting sealing with very little friction. On the Hyperstrada 821's fork tubes the seal works gently.

SKF Seals on the Hyperstrada 821

Fork seals on the Hyperstrada 821 wear with every kilometre, like on any bike. Wilbers describes the effect as a fork that feels race-prepared after the service. The Hyperstrada 821 is a bike where fork feel matters, and the seals play their part.

While the Fork Is Open

Pair the seals with Wilbers fork oil in the right viscosity. Opening the fork is also the chance to fit new Wilbers springs on the Hyperstrada 821.

Ordering the Right Quantity

Order a second kit if you want to do both sides. Where needed, Wilbers includes a spacer ring because the original seal is slightly taller.

Checking Your Seals

Wipe the fork tubes of the Hyperstrada 821 clean and look again after a ride; fresh oil means a leaking seal. A fork service with new seals is part of good maintenance on the Hyperstrada 821.

Fitting

Plan a fork service on the Hyperstrada 821 with the right tools, or let a workshop do it. Fresh oil and new seals go together.

Racing Background

Wilbers put the green seal through five years of IDM Superbike use on BMW bikes before recommending it for bikes like the Hyperstrada 821. For the Hyperstrada 821 that means race-tested sealing in everyday use.

Fitment and Compatibility

The fork on this bike is a Showa, 43 mm unit. Wilbers part number: 585-1146-00. If your bike has a different fork from the original, check the diameter before ordering.
