lets talk V4 steering head offset..

Yeah there is a spacer that can go either side of the round hub… long or even longer…
 
And, this is the big issue with the eccentric hub. It ..... so much, when it's moved.
So, you adjust the hub, and then adjust shock length to correct the ride height. But then your wheelbase is now different, meaning different weighting of each wheel, so you have to adjust ride height to get the balance back. But, now your geometry is out, so you have to adjust front ride height to compensate. Which takes a bit of trial and error...

Is some of that negated with having an adjustable pivot for the swingarm like the R has?
 
Any idea why the aftermarket hasn’t offered something like this to replace the eccentric hub?

it doesn't replace the eccentric hub it just offers a further option longer or shorter by turning the oval around... the eccentric and pinch bolts are still there..

Although interestingly the eccentric works in the arch below the centre line * like the 916 998 1098 etc) rather than above it like the street models...

So in my history of Ducatis one of the adjustable parts that was advertised was a 24.5 (std) or 23.5 steering head angle to adjust the rake. This of course reduced the trail by 6mm to a dangerous 90mm (std being 96mm) so you need to change the yokes to at least 30mm to get your 6mm of trail back. One of the better mods was to compromise the steering head insert to 'parallel' and make the rake angle 24.

So according to the Ducati tech specs my 22 V4 has a steering head rake of 24.5. interestingly they don't advertise it as 24.5 - 23.5 anymore but It looks like it could be rotated.

Now I think I read on here Rick you had altered/rotated your R head angle to make it the 23.5?

Does anyone make parallel inserts to get the 24 degrees?

So who's done this who's thought of this?

So did anyone actually answer this. My SF has the big head so I assume it can be set at 23.5. But doesn't the head eccentric move while not changing the trail? I raced my 916 on 23.5 with the forks raised and the eccentric moved to the far end (longer wb) and then compensated with the ride height adjuster. Never acted like the trail had been shortened. Least twitchy bike I ever raced.
 
Nope. Everyone seems to forget how heavy the wheels were. The cast mags available at the time were heavier than the current forged aluminum wheels. Not twitchy at all. A true testament to how absolutely transformative the 916 was. Every front end before it was crap IMHO. My friend had a 900RR at the time (16 inch front). The steering damper would get so hot it would take your skin off. Now that's twitchy. Did turn pretty hard ultimately.
