Grips may seem simple. They’re not.
Replacing 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
- the throttle to return with difficulty
- safety issues
Why is it difficult to fit grips?
Grips are not designed to slide on easily.
They are designed to:
- fit the handlebar perfectly
- withstand vibrations, moisture and temperature fluctuations
- ensure long-term stability
This means very tight tolerances.
In many cases, the grip is deliberately tighter than the handlebar diameter, precisely to ensure correct fastening.
Take care on the throttle side
The right-hand side is the most delicate part of the fitting process.
Key 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 throttle sticking
- 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 the proper tools often leads to:
- failure to fit it fully
- 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
Dirty surfaces
Residue on the handlebar, such as glue, dirt or oxidation:
- increases friction
- prevents correct fitting
Thorough cleaning is always necessary before fitting.
Lack of the correct tools
Many problems simply arise from not having the right tools.
Fitting methods
Recommended method: compressed air
This is the method most commonly used in the workshop.
Procedure:
- position the grip at the start of the handlebar
- blow compressed air between the grip and the support
- slide the grip into its final position
Advantages:
- quick fitting
- 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 may 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 should not slide on easily.
It must:
- require precision during fitting
- adhere completely
- remain stable in all conditions
If it slides on too easily, it is likely not fitted correctly.
When to contact a workshop
It is advisable to rely on a professional when:
- you do not have a compressor
- it is the first fitting
- you encounter difficulties
- you are working on the throttle side
A job that takes a few minutes in a workshop can become complex without the proper tools.
Conclusion
Fitting grips is an apparently simple operation, but technically delicate.
With the correct method and the right 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.
