Lowering front end of 750sf

Hey guys.  I wanted to lower my front end.  I found a few threads suggesting somewhere in the range of 25-30 mm.   

My question is how to do this?  The triple trees on the sf are shouldered so you cant simply drop the forks through the trees.    Is it as easy as just shortening the springs inside the forks by the length i want to lower it?    Or is there more to it?

Thanks
Dan
 
dan, 25-30mm has been suggested on the marzo forked triples
i don't think it is common mod on the 750

without being able to drop the yokes down the tubes (35's yes?)
the easiest would be to use a shorter front tire or longer rear shocks

if you shorten the springs inside the tubes you will reduce the range of available damping
and may find it easier to bottom the forks on bumps because of reduced travel
while the first thought may be to fit higher rate springs it may well make the forks less compliant
unless selected for your weight and riding style...

lowering it will also reduce cornering clearance

perhaps the real question might be what you are trying to achieve?

cheers,
scott


 
Are there spacers on top of the springs?

If so, whip 'em out and put in shorter ones. As Scott said, it will reduce the available suspension travel, but at least it will give you an idea of what the change in geometry will feel like. If it achieves the result you're looking for, you may want to think about a better permanent solution. If not, put it back the way it was.

Cheers,

Let us know what you are trying to achieve.
From memory yours is an SF1. They have fantastic neutral steering as they are. Lowering the front will reduce your ground clearance in corners. It will never steer like an R6 no matter what you do with it. To sharpen the steerung a bit fit rear dampers that are an inch longer, and if you get a good quality set the handling improves heaps into the bargain. There you get better clearance into the bargain. If it is general handling you are after then getting modern internals into your forks at the samne time will put you on the right track.  Don't start stuffing about with different preload on your springs, you will open a can of worms.
If you want advice then say what it is you are after. There are plenty of very experienced people on the forum who can point out your options.
 
I was searching through the forums for handling improvement mods and came across a few to lower the front end.  As Scott pointed out, that was for the 38mm marzocchis.  I have 35mm cerianis.   

Just looking for general handling improvment.    Funny you mention the R6,  i used to ride an R6 and CBR600.  maybe i'm just looking to get closer to what they offered in the handling department. 
 
I'm afraid you'll have to buy one of them, Den, as a Laverda is a different beast entirely.
I also have a CBR600 for training on. I cannot lap on it as fast as on my Lav750 racer. My last race was combined with the 600cc up to '87 calss. Only 3 of them finished in front of me from a full field of 36.
I just love that Laverda.
How hard are you pushing your Laverda to need to improve its handling? Generally a suspension update will set you right.
Regardless, you ride it a completely different way to a modern scalpel.
