As mentioned in another thread I'm compiling data relevant to the Frankenviffer "lifestyle"... :wheel:
From a search, I see that SAFE-T has already done something like this, but as I haven't seen the result, I'm happy to roll my own and post it when it is complete enough to be useful.
The table I'm creating is necessarily a mixture of OEM specifications, related calculations and physical measurements. In order to preserve the integrity of the data, I will not include in my table anything I cannot verify as coming from a reliable source. In the case of the OEM specs, that means the General Information section of the Honda Workshop Manuals. In the case of physical measurements, it will be difficult to gauge the reliability of these unless I do them myself--or know that they were done by someone who is familiar with measuring such things. For calculations I will use Tony Foale's software.
As for which data to include for each model, I am open to suggestions, but these are the ones I've chosen at the moment:
Caster Angle/Rake (OEM spec)
Trail (OEM spec)
Fork Offset (to be measured)
"Real Trail" (calculated)
Tire Radius (OEM spec)
Fork Length (to be measured)
Fork Spacing (to be measured)
Yoke Upper I.D. (to be measured)
Axle O.D. (OEM spec--done)
Wheel Hub Width (to be measured)
Brake Disc O.D. (from Braking catalog--done)
Disc Bolt Circle (from Braking catalog--done)
Brake Disc Offset (from Braking catalog--done)
Caliper Bolt Spacing (to be measured)
Master Cylinder Marking (derived from OEM spec)
(I'm not too bothered about the OEM spring rate, as I would expect that would be changed in any case to better suit the bike and rider.)
Below is the list of models I am planning to include in the table. Generally, it includes most Honda sport and sport-touring models with at least 41mm forks. If you think I've missed any significant models, please let me know.

If you do, and could give me the caster angle/rake, trail and master cylinder I.D. specs listed in the General Information section, I would appreciate it. No Haynes; no Clymer, please!)
I acknowledge that there are non-Honda options as well, but my personal preference is for "OEM-like" and to not mix manufacturers, so I ordinarily would not consider using R1 or Ducati parts on my bikes. Once this data set is more or less complete, I will post it and the non-Honda stuff can be added to it then. Fair enuf?
I hope this effort will prove useful to anyone considering making front end modifications to their VFR--any assistance in this project would be appreciated.
