In praise of the Zan? 750 Formula

Written by an owner, a certain Marco Pasquali.  Translated from the original Italian, with certain of the original words/phrases in brackets.

But sentiments I share (not least, "its spicy and sometimes difficult nature").

"I can speak from personal experience since I've owned one since 2001.

Mine is the final series, sold to race in the Trophy Series that should have been held in 2000, but which never got going because of the financial difficulties of Laverda (which was bought by Aprilia and then closed shortly afterwards when Piaggio bought Aprilia).

I've done many miles on the road, and I've also done a few outings on the track and a few time trials.  Believe me, it's an incredible bike in so many ways, a bike/chassis (ciclistica) that's first-class (sopraffina), but is touchy (sensibile), nervous, rapid through the bends if you move your body.  Frightening braking.  Thanks to the Brembo cast iron fully floating racing brakes, no other bike of those years brakes so hard.

The engine is much more powerful and faster than you think, especially when fitted with the open exhausts, electronics and camshafts of the Trophy kit  - which is even more developed (spinti) than the already well developed standard parts.

The Formula has larger valves than the standard 750S, has more compression and has the head and inlet ducts machined.  Its behaviour is that of a racing bike.  It has to be kept revving if you want to go fast.  You only have 2000 useable revs between 7500 and 9500, but it really goes a long way (li fa veramente tanta strada) considering that it's still only a 750 twin-cylinder based on a 1970s design. But don?t think that it struggles to hold the pace with much more powerful bikes around the curves of the passes of the Appenines. 

But it has some limits: it's uncomfortable and quickly tires you out; it vibrates a lot; it has a ridiculous turning circle (I don't know how they got it homologated).  The handlebars practically don't turn and you have to steer hard or you won't make tight corners - dangerous if you're on the wrong side or you need to avoid an obstacle at the last moment.

Overall it consumes very little.  It has a great range given the huge tank with the filler under the passenger seat.  The tank is underneath what is nothing more than a plastic cover for the voluminous airbox. This lowers the center of gravity and makes for good handling, but I repeat: only if you get used to riding it as it wants.  If you get carried away (uno si fa trasportare), or if you want a smooth and uncommitted ride, it's not the right bike for you. You want tyres with a pointed profile and not the standard 120/60 on the front - with that I've never been able to find a good way to ride it.

It?s a rigid bike.  It tends to jump over potholes and you have to adjust the suspension according to your own needs and the type of asphalt you will encounter.  Luckily the Paiolis are adjustable in compression, extension and preload, both front and rear - and the adjustments are perceptible.  The electrical system is delicate, never wash it with a jet washer, a bike to be maintained by an expert of the brand.  And use good oil and spark plugs.  The battery should always be kept fully charged or you may have cold starting problems.

Otherwise, the motorbike goes very well and I have never regretted 1 day of having spent so much to put it in the garage.  With that money, you could buy an R1 and have money left over to fill it up all summer.  But when you get to the pass, all eyes are on it.  It's beautiful, it's refined and it's got an exotic, atypical motorbike feel to it.  Only put one in the garage if you know you can compromise with it and that you can forgive its spicy and sometimes difficult nature."

well written. I have no experience whatsoever with the trophy kit, but with the street kit, the Series 2 is rideable from 3.000 to the rev limiter. below it is a bit rough but when warm, even 2.000 is somewhat OK. Clutch is rough (mine at least) in first gear when cold. Else it is a real beauty to ride, especially beyond 100km/h (when the wind takes load from your arms and back). Everything on that bike is sooo easy compared to the triples and even the old 750's. Even with me heavy lump on its back, it lifts the front tire in second gear just by pulling throttle wide open. still controllable, and the acceleration is just fun.

I learned to ride tight corners on it 1997 when I dropped my Jota in wet weather on the Reschen Pass in Austria and could not continue the ride down to the Laverda meeting due to a broken alternator cover. Friend of mine took me down on his 1200's passenger seat. Next day, the weather cleared up and Hubi, a Laverda dealer at that time who had a Zane 750 S with him down in Italy, offered me a test ride on this bike. I said I was a bit shy of dropping the bike, too, but he said its fully insured, I should not worry.

So, I took the chance, put the (still a bit wet) leather on and jumped on the bike. In a group of 6 bikes (BMW GS1100, Laverda Atlas, 2 x 1.000 Laverda and a 750 Breganze) we went up the Monte Grappa. First corners I tried to ride it like my Jota, which endet almost in a scary situation... Then I remembered what Hubi said: "Don't hold the handle bars to tightly and don't lean to much on them.  Try to hold your upper body by your back muscles and lean a bit more if corners get tight. The bike has plenty of space to the ground, you can lean as much as you like almost."

That done, I circled through the hairpin-corners with good speed (and sometimes a bit of clutch to help), stabilized the bike with the throttle and pulled the throttle open after passing the center of the hairpin curve, shifting up 2 times, braking hard, turning in, holding the bike with the gas etc. etc. etc.

I am not the best rider in the world, but this bike fitted like a glove! Mid of the mountain, there is a place where paraglider can jump off to sail down into the valley. I stoped at that place, parked the bike, took off the helmet and the jacket and then I heard the others coming closer. Still took them 2 or 3 curves until they reached the place...  :D

As said - I am not a very good rider, no where near being fast. But the bike was sooooo easy to ride once you understand how to get used to it, it was a real pleasure to ride. I always wanted one and that was the moment I was really decided to get one.

To give you the full truth, I need to admit that the particular bike had a serious engine damage the next day and I was soooo happy it did not happen when I was riding it...  :o One or more of the piston rings where broken or something similar. As it was still under warranty, Hubi got all the spare parts from the factory and repaired it.

I focused on getting the Jota back on the road, bought the 1000 SFC in 2000 as the Jota still wasn't road-ready but always had the Zane 750 in mind... 2005 I think it was, when OCT called me to tell me they have a 750 S Formula, last series, that I could have if I was interested. Oh how much I was...
 
Good comments Lothar - I find you can steer this thing with your head - in the riding position with your head forward you can?t really see anything of the bike so in the right gear it can steer where you look without much input which is not like pretty well any bike I have Had before then most of them were faired heavyweights Kawasaki?s Hondas and 10 years of 2 Hayabusas - yes the gearbox is tetchy at times and as for rough surfaces it is hard and choppy . The chain alignment marks are rubbish needs to be measured - I am still working on that - a chap on Sunday Had 3 rings showing on the forks mine has one - I can?t imagine how quick steering that would make it  - one of the Zane guys did 50k on his S so there is hope for some engines - have done about 1000 k so far and will  change the oil at 1600 - I do like the ramp up of power between 7 and 8 as above very two stroke !
 
on a testride i did, i was so disapointet. The engine vibrates verry nervously, powerband was only at high rpm, the foodrests where like to sit on your balls only, the steering was hard because too much weight is on the rear, cause of the tank. I was so sorry, because the bike looked good and was cheap. A Ducati 750 SS or a Guzzi LM could do all better.
 
some of them are not well maintained or not in good order. Looking at the production quality controles, to many bad things have passed their reviews...

It is for good reason that OCT f.e. - once they go for the big end bearings - also do work on several other parts, which makes the whole surgery a lot more expensive than "just" going for the bearings. I con only speak for the 3 or 4 bikes I have ridden (a 750 S, a Ghost Legend, a 668 Diamante and my Formula) and all of them - even differently - amazed me.

The Formula 2000 setup though is one of the most balanced and most powerful of all of them and very smooth to ride if you want to. It is clearly not a touring bike, it really asks going on the hunt. It looks like a street racer - and it fulfils every aspect of it.

if there were massive vibrations, something was wrong though. normally they do not vibrate to much. by far less than any Breganze...

only vibes i get are below 4k when asking for go !

I would not argue with any of that  :-X.

But, but, but  ...  :D

Ditto. I think Lothar's bike, being a 2000(?) model - as well as having had the magic hands of Piet/Roger on it  :) - came out of the factory a bit more refined (ECU/fuelling/ignition) than my 1999 (registered) bike.

Is that possible, Lothar?  Or am I just inventing things?

Craig
 
Hi Craig,

for sure, OCT's "magic hands" did very good on the bike - no doubt! Overall, besides the mechanical issues that are well known, the biggest benefit the bike could get is a completely new ECU. All WM16 and the previously used (650/668) equivalent have a programming in them that switches ignition between early and late constantly between 2.700 and 3.000 f.e. I assume (!!) as this is true also for Duc's, Guzzis and others of that time, this is a feature and not a fault: with the Laverda original gearing, the bike is around 50km/h in 3rd gear at 2.700 roughly. Noise emission tests in the EU go like this:

25 meters distance of measuring. You need to enter that 25 with 50km/h in 3rd gear and pull throttle wide open.

what happens on the Zane's (and Guzzis, and Ducs...) is, that the bike does not accelerate but just vibrate massively for - roughly - 25 meters... after that you reach the 3.000 revs and the bike accelerates freely - but then emission tests area is already passed...  ;)

So - the only way to make a Zane bike behave great is to put mechanically (end electrics...) everything how it should be, sync the fuel injection and - install a different ECU, as you can not find the reason for this behaviour in the programming of the chip.

My16M is a great alternative, as it is soldered into an original WM16 box and installs, looks and fits like an original one. Just, it is fully programmable and therefore removes this bad behaviour.
 
Thanks, Lothar.  Yes, I well remember the effort that you went to in order to work this out this 'feature'  (banghead) of the WM16 - so thanks again.  As you say, 2,700 is the critical threshold ...

As far as the My16M is concerned, I hadn't realised that Cliff Jefferies had managed to complete its development.  Do you know anyone who's using one?

Best fix for Ducatis is droping one tooth up front to a 14 from a 15.

Thanks for that info Vince.

Standard gearing on the 750 is 16:43.  Dropping a tooth on the front (and I don't even know if a 15 exists: there's no choice in the parts list.  Which doesn't seem right ..  (dunno)) will make the thing rev up even more than it does already.

Hmmm ...
 
I bought an Aprilia Tuono Factory new in 2007. A complete pig in traffic until you fitted the smaller gearbox sprocket (supplied with the bike), a pair of Akrapovic end cans and the dealership changed the mapping on the ECU. Absolute night and day difference. You then had the bike that Aprilia designed instead of the bike they had to sell because of regulations.

I have one that at least can start the bike now (thanks to Matthias Geist!), but it is far from completely programmed... Matthias invested to much time in it and my knowledge of mappings and the hole system is way to limited to make it really show it's capabilities. If I only had someone near me that knows how to set it up, I would really love to feel the difference...
 
A little testimony to the difference the My16 can make.  The bike is a Guzzi V10 Centauro.

"I recently took delivery of one of Cliff's My16M ? I loaded up the latest map, dialled in the TPS idle setting , then took the bike for a spin around the block.

I was immediately struck by how much smoother the bike was at small throttle openings and in the lower rev range. Whereas before it was all a bit notchy below 4K and the throttle was doing the 'light switch' thing, now it was like riding a totally different bike!

Then I took it for a trial blast up a 7 mile stretch of dual carriage way.  At first I found the response of the bike a bit deceptive as it was all so smooth, everywhere in the rev range.  It was only by noting where I was changing up and actually looking at the speedo - plus the rapidity with which I was coming up on other traffic - that I realised how quickly the plot was shifting and how near I was to needing a change of underpants.

As you can probably gather, the initial impression was very, very favourable and now that I've put a few more miles on it, I can't fault it. So the verdict is, money well spent."

 
From my memory of posts years ago Cliff is in Sydney and one of the Sydney club blokes owns one of the last bluse and orange zanes. But that doesnt mean horses and water can meet. When I see Sasha or Dave next I will ask.

I was in contact with him a few years ago and he had done no further Laverda development.
