View Full Version : Ceriani front end.....

So i have a Ceriani front end. It came with the BSA I bought. It is the Flat Track one, not the racing forks that are a little more expensive in price.

The thing is they seem to be sitting a little too long for my liking. After getting my frame back it just seems like the frame and forks combo don't look quite right for what I want to achieve.

This leaves me with 2 options i believe.

1. Shorten the forks. Which is kinda hard to bring myself to do because of the allure of a Ceriaini front end.

2. Trade the fuckers out for a set of stock unit BSA forks and something else.....

I guess what I'm asking for is possibly advice on shortening the bastards without taking them apart to have the sliders shortened on a lathe.

Meaning has anyone had any luck with cutting the springs and using spacers/lugs. And how much did you shorten them?

Or

Shoot me a trade offer....

Shit....

Should have known I was going to get a shit ton of I'll trade ya responses.

It's not that I'm against trading, I just want to know if anyone has any experience lowering these things. Italians never make anything simple, and I have dug into these and am not sure if I can do the age old cut the springs drop in a spacer, or if the fork sliders need to be machined down.


And to give you all some info in the front end.

Its in damn good shape. The fender mounts are shaved off and the legs have been polished. They could stand with being hit one more time if you want that mirror finish. All the hardware is there and its pretty nice, not knicked up to all hell. The trees showed a bit of weathering so they have been lightly sanded and are either waiting to be painted again, or shell blasted and polished.

I also have a spare set of brand new fork seals, and a pair of NOS Ceriani headlight brackets. Just some info so if you guys want to make some offers you know what you are dealing with.

And when I say bits...

I need a few things but I'm pretty damn specific of what those things are. Stubborn in my head I guess.

Like I said if I can't get any lowering info and I mock up a set of stock BSA forks and like em, Id be more than willing to trade.

Ya, seen that one too.
Lowered plenty of Brit front ends, a couple of jap front ends too and we all know how simple it is for harleys.

I just don't feel like chopping up a set off perfectly good springs, only to find out that its going to fuck up the whole front end, and I'm stuck waiting for a new set of springs off egay cos its not like ceriani springs are an order that i can place at the local dealer.....

Also it seems like the pre-load spring is on the top of the tube set-up. The first lug you take out at the top has a stiffer 3.5" spring that needs to be compressed by the lug, which I'm assuming preloads the longer spring.

So the question I guess is if I just cut the longer spring and reduce the overall length I'll lose the pre-load and maybe have a soggy feel without a spacer.

Specifically I was hoping someone had some experience dropping a spacer down the tube and if it worked or not?

After getting the BSA frame back and throwing the 18" on the back, the forks were kicking up quite bit so I figured I'd lower them a few inches to make the stance look right.
Well after checking the Nazi (Jockey) journal for any tips. I kept getting the same response. Why would you lower Cerianis, they are rare, I'll take 'em and more shit like this.

Long story short. You want to lower them here's how you do it.

Anything shorter than 2" will require a slug to make up the difference.

They are little more complicated that a brit or Harley front end, but use the same principals. The only difference is the preload spring is at the top of the forks not the bottom.

This works out to your benefit. slide out your springs and cut that 2" off, slide the springs back in, and drop in the preloads, and you should end up with the preloads sitting at about 1/4" on the threads, giving you a 1/4" of preload still. All this and no slop.

Now if you want to go more than 2" you have to take your forks apart cut your springs, match the length of your spacers to your chop, and fit those spacers over the bottom of the actuator cup and Bob's your uncle.

I would however recommend measuring the depth of the actuator cup and adding it to the amount of spring you have cut off, and making a set of spacers that will be a smaller diameter on the bottom to fit into the cup and a bigger diameter on the upper half for the difference in the spring length . This will completely eliminate the chance that over time your Bojang spacer might fall into your actuator cup and cause a nasty slop.


This was taken from my blog, hope this helps...
