 Although girder forks are associated with early motorcycles, the British Ariel Ace, a modern sports motorcycle, has an alloy space frame and a matching girder fork.This Ariel girder fork is just as prone to brake dive as any telescopic fork, but is claimed to be more resistant to torsional twisting.The Saxon-Motodd (marketed as Telelever by BMW) has a wishbone that mounts to the frame and supports the monoshock unit.
