Grips look simple. They are not.
Replacing the grips is often considered one of the easiest jobs to carry out on your motorcycle.
In reality, fitting rubber grips is one of the most underestimated jobs and, at the same time, one of the most critical if done incorrectly.
Incorrect fitting can cause:
- the grip to rotate while riding
- difficulty with the throttle returning
- safety issues
Why is it difficult to fit grips?
Grips are not designed to slide on easily.
They are designed to:
- adhere perfectly to the handlebar
- withstand vibrations, moisture and temperature changes
- ensure long-term stability
This means very tight tolerances.
In many cases, the grip is intentionally tighter than the handlebar diameter, precisely to ensure correct fitment.
Pay attention to the throttle side
The right-hand side is the most delicate part of the installation.
Main features:
- it does not fit directly onto the handlebar
- it is installed on the throttle tube
- it has a different internal structure
Incorrect fitting can cause:
- slow throttle return
- partial sticking of the throttle
- loss of control of the motorcycle
This aspect has a direct impact on safety.
Common mistakes to avoid
Forcing it on by hand
Trying to fit the grip without suitable tools often leads to:
- failure to install it properly
- deformation of the rubber
- uneven fitting
Using excessive force
Applying force without technique:
- damages the material
- does not solve the problem
- increases the risk of mistakes
Unclean surfaces
Residue on the handlebar, such as glue, dirt or oxidation:
- increases friction
- prevents correct installation
Thorough cleaning is always necessary before installation.
Lack of the correct tools
Many problems simply arise from not having the right tools.
Installation methods
Recommended method: compressed air
It is the method most often used in the workshop.
Procedure:
- position the grip at the start of the handlebar
- inject compressed air between the grip and the support
- slide the grip into its final position
Advantages:
- quick installation
- no damage
- high precision
Alternative method: lubricating liquids
Possible solutions:
- alcohol
- specific sprays
- soap and water solution
Warning:
- the liquid must evaporate completely
- any residue can cause the grip to rotate
Advanced method: glue
It is a solution to be used only in specific cases.
Advantages:
- permanent fixing
Disadvantages:
- complex removal
- risk of irreversible mistakes
The key principle: grip = safety
A proper grip must not slide on easily.
It must:
- require precision during installation
- adhere completely
- remain stable in all conditions
If it slides on too easily, it is likely that it has not been installed correctly.
When to contact a workshop
It is recommended to rely on a professional when:
- you do not have a compressor
- it is your first installation
- you encounter difficulties
- you are working on the throttle side
A job that takes only a few minutes in a workshop can become complicated without the proper tools.
Conclusion
Installing grips is an apparently simple operation, but technically delicate.
With the correct method and suitable tools, it can also be carried out independently.
Without experience or equipment, it is preferable to rely on a workshop to avoid problems and ensure a safe result.
