Top Steering Bearing Taper Roller Conversion Post 65

Taper Roller Upper Steering Bearing Conversion for post 65 models.

The Lambretta top steering bearing, with tiny caged balls, is bicycle technology and not really up to the job of high performance engines and powerful front disc brakes that are used today.  With the old set up you have the problem of the bearings often coming loose, or becoming notchy if you tighten them too much.

 This is the solution, change to modern motorcycle technology and use a taper roller bearing, but this conversion is not as easy as it looks. The problem is that a taper roller bearing is thicker, leaving very little space for a locking ring or requiring other adjustments so that the bearing does not come loose.

 Casa Performance have developed a very clever smart solution which permits a taper roller bearing to be used in the original space at the top of the fork tube. The clever part is a special thin locking ring which has a lip that sits perfectly inside the upper part of the bearing. This lip means the bearing self-centralises with the steering tube every time.

 With the supplied 38mm steering spanner you can then fit the second lock-nut to tighten the assembly, which will prevent your bearings from coming loose.

Casa Performance`s completely ‘Plug-and-play’ taper-roller upgrade to those troublesome old ball bearings.
