One thing I had not realised before, is that looking closely at the bike in the "staged" Hollister picture, it is clearly fitted with one of those ratchet-shift conversions that were being discussed a little while ago
this one, as ever with old Harleys, appears to be a horse of a very different colour going by the same name http://venturamotorworks.wordpress.com/ ... shift-pan/ from what I can see, it is a ratchet semi-automatic shift-and-clutch actuated by a handlebar trigger. I'm far from clear how this bike would be ridden, from what I can see it is an up-shifter.. ieit changes up, as in drag racing; how you would ride this bike on the road, I'm unclear?
how many more of these things are there? http://1.bp.blogspot.com/_Z8l9QhPa6mg/T ... speed1.jpg this one also appears to be a semi-0auto clutch-and-shift, but using a pedal this time
