Suzuki GS 400 B/C/EC/EN 77-79 Tapered Headrace Top Bearing - Upgrade see notes

On models that originally took cup and cone steering head bearings, upgrading to tapered headrace bearings is a popular and cost-effective choice. The ball bearings used in the original cup and cone have only two small points of contact on each ball bearing, which makes them more prone to failure than spreading the contact across the entire edge of a tapered bearing. Tapered bearings therefore last longer, and give better stability, than cup and cone bearings.

For some early (pre 1979) Suzuki Models:

When first upgrading from cup and cone to tapered bearings, on some models a modification may be required on the steering stem; please see below:

In order to install tapered bearings on early Suzuki models it may be neccessary to modify the steering stem as per the above sketches. When the stem is modified verify the bearing will slip into place.

A note from one of our customers (owner of a Suzuki GT 380):

"If you want to add a note to say that the stem is mild steel and is easy to reduce, I used a dremel grinder and then polished with fine emery paper."

48x25x15mm Please note on some Suzuki Pre 79 models you may need to modify the steering stem

Care And Maintenance

Although bearings are subjected to large amounts of stress and are continually being used to fulfil various duties, they are precision made and typically last a long time (bearing failure is often due to improper installation and fitting). However high-mileage bikes and dirt bikes, which are exposed to a lot of mud and water, can become vulnerable and require attention sooner than expected.
