Steering head inserts and ~Rake angle

Ducati Forum

Help Support Ducati Forum:

So 959 and V2 same part numbers and 24 degree
1299 and 1299R same part numbers and 24 degree
All Panigale V4 2018 -2024 inc R (not SL) same part number for top and bottom 23.5-24.5
 
this is a V2 Baylis std top insert looks like.... the single bolt is the front.....

That one has a lot of offset at least 2 degrees.

yeah and the L to the clutch lever side. Yet V2 Bayliss is 24 degrees...

the bottom insert on this bike is a different part number to the top one. It would be interesting to see where that is at. Whether that is kinda forward of the centre too but less than the top to give the rake angle...

So Andy since the 24 degree inserts would almost be a total lathe part (you have to add the locating slots, ratail?) are you going to make some?

That could be the plan ..

Ideally a 24 degree parallel pair of inserts with the bearing aperture sat back a bit to increase a bit of trail that might be lost 24.5 to 24 without the need for expensive offset yokes… at this stage…
 
Nope if you move the plane thru the center of the bearings back towards the rear of bike keeping that plane parallel with the centerline of the headstock then you're only changing the wheelbase.
 
well there you go...

24 degree rake
offset from the centre 5mm
which means you can go forward with the steering spindle but then return the wheel back using offset yokes to increase trail and not suffer the classic ducati big rake/trail front wheel hitting the radiator issue..

there is a factory list of a million of these in different angles and offsets.... god knows how much they would cost.

thank god for a lathe..

400 hundred euros ouch. Pure lathe part if you ignore the lightening bit. Which you could do on a drill press with a rotary table and an end mill if you so desired. Easy part. The factory inserts are $54.

It would be good to know what factory part fits what. 24 degrees on the V4 should give 99 mm trail.

Ducati blurb says 24.5mm gives 100mm trail with the std 30 offset yokes.
( I know on the 998 std trail was 96 with 24.5, and 90 with 23.5 with std 36 offset yokes.)

So I think 24 will lose a bit more of trail with the std 30 say down to 97. the good news is that it tends to be like for like so a 28 or 27 offset would bring it back to 100 obviously on paper.
