Gripster UP

GRIPSTER UP 2.15'

The Gripster UP prevents punctures, or more precisely the tearing of the inner tube valve, which occurs when your tire rotates on the rim.

The wheel rotates:

If you have ever seen a tire rotate on its rim, you know the damage this can cause to the inner tube valve:
it gets cut and you end up with a flat tire.
To avoid this phenomenon, you can install a Gripster UP inside your rim,
it will press your inner tube against the tire which will prevent the rim from rotating without the tire.

What size for my motorcycle?

There are 3 sizes of Gripster to fit front and rear wheels, and cover all engine capacities.

• 1.60’ For front wheels regardless of engine size, and rear wheels for 65 cm3 motorcycles

If you have an 85cc, you will have to choose between the 1.60’ and the 1.85’ depending on your wheel size.
