[QUOTE="Dr Ivan D. Reid"]\nI don't know about Guzzis, but I certainly noticed it on my\nGT380M. I put a bikini fairing on it whose centre-of-pressure was possibly\nahead of the steering axis and which obviously added to the moment of\ninertia of the steering system anyway. It then became prone to steering\nwobbles so I swapped the forks and disk over (the wheel was already\ndrilled and tapped for dual disks) so the caliper was behind the fork.\nSteering stability returned.[/QUOTE]\n\nHmm... the R80 does that in a band at 75+ MPH (in 'test' conditions,\nobviously). It's likewise set up for dual disks.\n\nI wonder...\n\n\nRegards,\n\nSimonm.
