This shows how quick and easy it is to install a tapered roller bearing conversion kit on your Triumph or BSA motorcycle. It is a nice upgrade from stock, we also have bearing kits to put a 1" stem front end (springer, HD big twin or sportster) on your Triumph or BSA.
Once you remove the front end off of your Triumph or BSA motorcycle, you will likely have the stock races and loose roller bearings that will fall all over the floor and roll out of sight. A tapered roller bearing conversion kit is a significant upgrade, offering smoother installation and improved durability compared to the original components. These modern bearings and races provide long-lasting, smooth steering performance and are a great choice for stock frame and front end combinations.
In addition to these upgrades, we also produce bearing conversion kits that allow you to fit a front end with a 1" stem—such as girders, springers, HD Big Twin, and Sportster forks—onto your Triumph or BSA motorcycle. For Harley-Davidson owners, upgrading with wheel bearings and races for Harley-Davidson can provide the same smooth handling and reliable performance, ensuring your motorcycle rides like new.
Shown below is the stock top race with a few remaining ball bearings.
The stock races have to be knocked out of the neck. There is one both top and bottom. A long drift held at an angle so it will catch the inside lip of the race makes the job easy (usually). Sometimes they can be seated really well and take a good amount of effort to remove. Move the drift around as you knock it out so it comes out evenly to make it easier.
Once you remove the stock races, you will want to place your new tapered bearing races on the neck, and using a deadblow hammer or a piece of wood and a hammer, drive the race into the neck.
Before you insert your bearings you want to pack them with grease. Work them around in your hand and really get it in there, you want to get the bearings thoroughly greased.
Depending on what bearing set you are installing, the dust cap would go over the top bearing, and you slide your forks in from the bottom. It can be much easier to install your forks if the front wheel is off of them. Also, if you are rebuilding your front end, you can put the trees on the frame, then insert your fork legs.
