These HD51 pin-mounted fork extensions offer the same functionality and capacities as the strap mount models, but come equipped with a quick disconnect pin system for easier installation and removal.
Regulations require that standard fork extensions do not extend more than 50% of the length of the fork they are installed on. Example: a 48” fork may have a maximum of a 72” long standard fork extension installed OR the existing fork length x 1.50. The CBI series HD-50 and HD-51 fork extensions are manufactured and rated for this type of installation. In the event that more than 1.50 times the fork length is needed, see the CBI series EHD-61 fork extensions.
