Motorcycle maintenance can be a daunting task for most people, yet it is an integral part of owning a bike. One such task that needs your attention is lubricating the steering bearings. If you own a Triumph Thruxton R, this guide will walk you through the steps on how to properly lubricate the steering bearings on your bike.
Understanding the Importance of Lubricating the Steering Bearings
Before diving into the specifics of how to lubricate your steering bearings, it’s essential to understand why this task is crucial. The steering bearings, located at the front of your bike, are key components involved in the function and operation of your motorcycle. They ensure smooth steering and enhance your bike’s overall performance.

The Triumph Thruxton R is a high-performance bike, and as such, it requires regular maintenance to keep it performing at its peak. A well-lubricated steering bearing not only guarantees smooth rides but also prolongs the lifespan of the bearing, saving you costly repairs or replacements in the future.
Grease, the lubricant used in this procedure, reduces friction between the bearing and its housing, preventing unnecessary wear and tear. However, over time, this grease can get contaminated, reducing its effectiveness and leading to stiff steering or unpleasant noises while turning. Therefore, lubrication isn’t just a one-time task; it’s a routine that needs to be upheld for your bike’s optimal performance.

Identifying When Your Steering Bearings Need Lubrication
Now that you understand the importance of lubricating your steering bearings, it’s crucial to know when to perform this task. Noticing the signs of a bearing in need of lubrication can save you from potential damage to your Triumph Thruxton R.
If you notice any stiffness while turning your handlebars, or a knocking sound when you hit a bump, it could be a sign that your steering bearings need lubrication. Also, if your bike is wobbling at high speeds or your steering isn’t returning to the center as it normally should, it might be time to lubricate the bearings.
It’s also worth noting that even without these signs, it’s good practice to lubricate your steering bearings at least once a year or every 20,000 miles, depending on your usage. Your bike’s manual may also provide specific guidelines on when to perform this task, so it’s advisable to consult that as well.
Gathering the Necessary Tools and Supplies
Before beginning any maintenance task, it’s important to assemble all the necessary tools and supplies. To lubricate the steering bearings on your Triumph Thruxton R, you will need:
- A motorcycle stand or jack
- A set of metric wrenches
- A set of metric sockets
- A torque wrench
- A rubber mallet
- A bearing driver set
- Heat-resistant grease
- Cleaning solvent
- Rags or paper towels
These tools are generally available at any automotive stores or online. It would be best if you used a quality, heat-resistant grease for this task, as it can withstand high temperatures generated while riding without losing its lubricating properties.
Step-by-Step Guide to Lubricating the Steering Bearings
Now, let’s delve into the step-by-step process of lubricating the steering bearings on your Triumph Thruxton R.
Step 1: Prepare Your Bike
Firstly, place your bike on a stand or jack to elevate the front wheel. Ensure the bike is stable before proceeding with the process.
Step 2: Remove the Front Wheel
Next, loosen and remove the front wheel. You’ll need your metric wrenches and sockets for this step. Be careful to keep all nuts and bolts safely, as you’ll need them to reassemble the bike later.
Step 3: Dismantle the Steering Assembly
Proceed to dismantle the steering assembly. This involves removing the forks and the handlebars. Be sure to handle each part with care, particularly the forks, as they are delicate and can easily be damaged.
Step 4: Remove the Bearings
With the steering assembly dismantled, you can now access and remove the bearings. Use your rubber mallet and bearing driver set for this task. Remember to remove both the top and bottom bearings.
Step 5: Clean and Inspect the Bearings and Races
Once the bearings are removed, clean them and their races using your cleaning solvent and rags or paper towels. Inspect them for any signs of wear or damage. If they’re damaged, they’ll need to be replaced.
Step 6: Apply the Grease
With the bearings and races clean and dry, apply a generous amount of your high-temperature grease. Make sure the entire bearing is covered.
Step 7: Reassemble the Bike
Finally, reassemble your Triumph Thruxton R. Replace the bearings, reattach the steering assembly, and put the front wheel back on. Ensure all parts are tightened securely with your torque wrench, following the bike’s manual for the specific torque settings.
With these steps adhered to, you should have successfully lubricated the steering bearings on your Triumph Thruxton R. However, always remember to test ride your bike in a safe area to confirm everything is working perfectly.
Regular Maintenance of the Steering Bearings on a Triumph Thruxton R
Besides lubricating the steering bearings at least once a year, regular check-ups and maintenance are essential to ensure the longevity of your Triumph Thruxton R. Remember, proper maintenance is not limited to the steering bearings. Other parts such as clamp bolts, the steering stem, and the top yoke also need your attention. The engine oil should be checked and replaced regularly, and the exhaust system should be inspected for any signs of damage or wear. You should also ensure the front brake system is functioning correctly.
The Triumph Bonneville, a relative of the Thruxton R, has the same maintenance requirements. For both bikes, it is advisable to clean out the top and bottom steering head bearings periodically, particularly after a long ride. The use of fork oil is recommended for the forks, to keep them in good working condition. For owners of the Triumph Thruxton scrambler, regular maintenance should also be upheld. The manual of your Triumph bike should provide a detailed maintenance schedule.
Tapered bearings can be an excellent substitute for your regular head bearings, as they are known for their durability. They are resistant to wear and tear, even under extreme conditions like high-speed wobbles. Using the right tools, you can replace your regular head bearings with tapered bearings. For example, you will need mounting bolts and a torque wrench for the steering stem, and fork springs for the forks.
For all these maintenance tasks, always remember to test your bike after each procedure. A safe test ride will help you ensure that everything is functioning as it should.
Conclusion
Maintaining your Triumph Thruxton R can be an engaging and rewarding task. Lubricating the steering bearings, in particular, is a crucial task that can significantly improve your bike’s performance and enhance your riding experience. The task might be daunting, especially if you are not mechanically inclined, but with the right tools and a detailed guide, it is manageable.
Remember also to attend to other parts of your bike such as the front sprocket, the forks, and the exhaust system. Regular maintenance of these components, as well as the steering bearings, will keep your bike running smoothly. Always consult your manual Triumph for specific maintenance guidelines for your bike.
Consider investing in durable alternatives like tapered bearings for your steering head, and remember to regularly replace your engine oil. These practices will prolong the lifespan of your bike and save you significant costs in future repairs or replacements.
While performing these tasks, safety should always be a priority. Always test ride your bike in a safe area after any maintenance task. This will help you confirm that everything is working correctly. Keep these tips in mind, and your Triumph Thruxton R will give you many smooth rides for years to come.
