Ohlins Fork non radial pinch bolts
Fitment - Non radial Ohlins fork
This 6mm bolt is used to nip up and pinch the bottom of the fork leg together and prevent the front wheel spindle from turning as you torque tighten the wheel nut.
As it is only a pinch bolt, it does not require a lot of force, only 6-8 Nm for the Ohlins, so please be extremely cautious when tightening them. If over tightened you run the risk of cracking the lower fork arm which will then render your forks unusable.
They are a great replacement for your original ones that will give a fresh new look to your Aprilia.
