good luck under heavy braking! Suspension travel looks like 100mm only ...

Gert, total travel is 120 mm (like many modern street bikes). Springs are 9.3 N/mm,  compression damping is excellent; I have  no fear for heavy braking, but will make some stops and let you know.

Looks good Hein.
Is that a Ceriani type front mudguard with a special bracket holding it on to the fork brace brackets?
 
looks like there may be a clash on full bump, full braking with the mudguard and middle ex pipe?
put a dob of expanding foam on the guard then give it the treatment and see if you get any stuck to the pipe, when cold brake cleaner does a good job of shifting it.

Grant, yes indeed, its a mudguard like you have on POP, but without the bars. Bracket is homemade bij GvD.

Pic is with turned wheel, taken from the front, so gives a false idea of distance (header/mudguard). Don't worry, there is no chance of touching, let alone "clash"!
These stanchions, stiffened up by headstock extension do not bend.

Regards, Hein

Axle is offset to the rear of the fork centreline, so you've got a few mm more trail with those forks. Probably not enough to make any huge difference, but it would be interesting to hear your comments on how it steers. It may feel more stable and not steer as quickly as it did. That's not necessarily a bad thing if you're using it as a long distance touring bike.

Hi Cam, You're right, but changing from non parallel (stem/stanchions) Ceriani, to Marzocchi gives the opposite; less trail.
I have only ridden the bike for a short distance, but the first impressions are: Quicker steering, comfortable ride (that will be due to the Andreani kit).
Indeed, this bike is used as a long-distance tourer.
My other bike (should have been a 750 Laverda) is more suitable for track days and fun.

Ah, OK. That's the same as my RGS Mongrel track bike which also has a BMW front end. I used the BMW triple clamps which reduce the trail more than the axle offset extends it. I think the bike handles nicely on the track, but I don't push it too close to the limit.
 
a cable tie wrapped around the fork leg, and only just tight enough to stay put is a good way of measuring static sag and full movement of your fork travel
