Laverda 750 S

Eric Bergman’s Laverda


My 1973 SF1

I bought a Laverda 750 SF1 in October 1998. I I wanted a triple but this is I found and I have no regrets. I was at first about what is because of the twin disc brakes, which were for the SF2 in the 1974 model year. But my came fromthe factory a drum brake and had a later end grafted on at some time in life.

The serial number indicates it was built in the spring of and it has the CEV headlight and Lucas switchgear was only used on the 1973 The paint is not original but seems to be a match to the original color.

My just arrived home

an SF1 is supposed to look like.

a Laverda 750 sounds like. is a recording of the legendary SFC production made by Marnix van der Schalk.


I bought this bike in in August 2000, to have a to ride in Europe. It is serial 6349, a first-series SF. The papers say it was registered on October 25, 1971.

These models are distinguished the later SFs by the beautiful gas tank, is still the same one used on the and the first-series Laverda drum in front, which has the actuating pulling toward each rather than the later arm. There are also differences of course.This model the 750S) was intended to have bell-mouths on the carbs, but a rudimentary air was added in some markets. It is hard to find a filter for these now.

I have back to the open bell-mouths the bike runs better way and I don’t put many miles on it.

there are many stories of woe and with the drum front on early Laverda twins, the one on bike works wonderfully, than most of the disc systems of that era. good feel and stopping I hope I don’t have to it for a long time!

The handlebar (left and right ) and instrumentation on bike are typically high

The engine in this bike is different from the SF1. The SF had compression, a hotter cam and smaller It has a much more rambunctious than the SF1, although I am it is not any faster.

These engines were prone to pinging, I have experienced. The answer in retarding the timing, fuel and very cold plugs, NGK in particular.

Here’s a shot the right front quarter.

The Bike

In the fall of 1998 I was for a while in Berlin, and I noticed a 750 parked less than a from where I was staying, on in the Charlottenberg district. I admired the greatly and took these It turns out that this is an SF1 model, apparently very (The handlebars are not, and the has excised the unpopular exhaust pipe under the rear of the This was about a month I bought mine.

Coincidence? I not!

The Teardown, Part 1

I had to down my engine to find the of a shifting problem that one day (in February 1999) on a ride, almost immediately by a very grinding noise from the of the gearbox. I hoped I’d the problem in the clutch area. are some detail photos of a few that I took during the

I took a close look at the pressure plate because of the around the inner diameter you can see in the photos, but in the end I decided it could not be to the problem.

I also poked in the gearshift mechanism which is without pulling the engine. was nothing worrisome there. I had advice (and temptation) to bolt it back up and keep

Knowing now what the problem is, it’s clear that would have worked for a but then it would have really ugly at some

The Teardown, Part 2

Well, I bit the and split the cases to inspect the itself, and I finally found the of the trouble: broken mainshaft. unusual from all accounts. me!

Here are some photos.

Pitting on the 5th gear-all the other gears good.

Detent spring people thought this turn out to be the problem. It would been cheaper!

The culprit. The sheared cleanly at a cross-drilled oil which runs in a bush the 5th gear. Here’s another .

I ended up replacing several in addition to the mainshaft, and had some and bearings replaced as well, to the of about $600. The gearbox has running fine since the although it seems a bit easier before to miss shifts if are not made fairly convincingly. I may to make some adjustment in the mechanism.

The Big Headlight

After I had riding the Laverda again for a I had some reason to poke inside the headlamp shell, and I that the halogen H4 bulb was in there did not fit in the reflector of the CEV headlight, was not designed to take such a The H4 had just sort been in the CEV reflector, a hopeless bodge. In the bulb which fits the CEV is a bit hard to find, although Haerter has them.

I started thinking about how to the CEV unit to a halogen bulb and various strategies, but the very CEV headlamp just won’t any other readily-available headlight I finally decided the bike a bigger headlight to suit rather massive presence.

One would have been to for a Bosch 200 mm unit which was on later SFs, but a friend I could come up with a cheaper and very acceptable from a Japanese bike. are indeed a few reasonable choices, but I was at the motorcycle junkyard I found a huge headlamp that was on several big Yamahas and Suzukis in the 80s.

It has a very nice shell in black, with openings for wiring access and drain holes-it’s not meant to be but to drain well and dry out after the The one I found was labelled Koito on the but I’ve seen others different lenses. These are expensive. I paid $125 for but I am completely happy with it.

The Bosch would likely cost even more, of all the high-bucks BMW enthusiasts out there. The SF really needs a big, headlamp in my opinion, and they get any bigger than this. are a few pictures:

The installation was completely There is a bracket on the bottom of the shell which is intended to with a clamp to allow the of the shell to be adjusted and fixed. It be easy to add a small bracket to the lower triple clamp to it, but I haven’t done it yet, and the seems to stay put.

The ears have to be angled out to hold the big shell, but it is not a problem in my
