It could reach a top speed of 225.5 km/h / 139.5 mp/h.  

==Engine==
The engine was a Liquid cooled cooled Four stroke, parallel twin. DOHC, 4 valve per cylinder.. The engine featured a 11.5:1 [[compression ratio]].  

==Chassis==
It came with a 120/60 ZR17 front [[tire]] and a 160/60 ZR17 rear tire. Stopping was achieved via 2x 320mm discs 4 piston calipers in the front and a Single 245mm disc 2 piston [[caliper]] in the rear. The front suspension was a  Paioli Racing Inverted adjustable preload, rebound & compression damping while the rear was equipped with a Paioli Monoshock adjustable spring preload, rebound & compression damping. The 750S Sport Formula was fitted with a 16 Litres / 4.2 US gal fuel tank. The bike weighed just 185.0 kg / 407.9 lbs.

== Overview ==


Laverda's Formula 750S is
essentially a factory-built special edition of the basic Formula, with
extensive engine tuning and even more special chassis componentry.
The original Formula was a 650,
built in 1996, with the 750 Formula following a year later in 1997.
The engine work was more
extensive than most factory specials, and took the Formula almost to a race
tune straight from the showroom. Uprated cams, revised fuel-injection
settings and carbon-fibre Termignoni silencers all boost top-end power to an
impressive claimed figure of 69kW (92bhp) - almost as much as the more
successful Ducati 748, another 750-class twin.
The chassis also compares well
with the 748, being considerably lighter, and with suspension and braking
components every bit as impressive as the Ducati.

Fully adjustable Paioli
upside-down forks and monoshock, fully-floating Brembo racing brakes and
lightweight Marchesini wheels all play their part in giving the Formula
impeccable track manners and sharp handling.
The polished aluminium beam frame
looks much more impressive than the Ducati's thin steel-tube affair,
although the Ducati frame is stiffer than it looks. A single-seat
race-style fairing incorporates
stylish cooling louvres and twin endurance-style headlights, and is finished
in Laverda orange, the firm's distinctive racing colour. Despite the
impressive spec, and some success in endurance racing, the Formula still
suffered from the weakness and rewy nature of the old parallel twin-engine
design, and it was never as successful as Ducati's 748.
Indeed, at the time of writing,
Laverda's future as a whole is very unclear - the troubled firm was bought
by Aprilia in 2001, and there is, sadly, little sign of any new Laverda
motorcycles being produced in the immediate future.



750 Technical Information

The following modifications were needed on the early 750S models (those with
the half fairing). Regarding machines imported in the UK, those with the
following frame numbers already had the changes when built at the factory: 1479,
1520, 1526, 1541 and 1542. The modifications were done under normal warranty
conditions. However, for owners of grey import or other such machines, the list
of modified parts and their part numbers is at the end of this listing.
1 New PMS rotor. The thickness of this rotor has now been increased, from
1.5mm to 4mm. This has been done only for the purposes of reliability.
2 Oil pressure valve - diameter increased to improve oil flow.
3 It was brought to Laverda's attention that the water temperature gauges
were not all calibrated correctly. There is now a diode available that plugs
into the back of the gauge itself.
4 Water pump assembly. The new water pump now has a bigger impeller shaft,
and also bigger seals and bearings. This part, from now on, will only be
supplied completely assembled within the clutch cover. This new part should be
fitted in the event of a water pump failure. It is not necessary to change the
current pump fitted to the bike if there have been no problems with it.
5 Balance shaft. A new balance shaft is fitted to the latest 750s. The
difference between the old and the new one is that the new one is thicker and
stronger, to reduce the flex in the shaft. This part should be changed in the
event of a water-pump failure, as described above.
6 Headlight bulbs. The bulbs available for the 750s are now 55/60w halogen
bulbs instead of the 30/35w bulbs fitted as standard.
7 Fuel pump. The pressure of the fuel pump has been increased, and it now
also has a lower drain on the battery, and an improved filter system. This part
can be changed with the fuel filter under normal servicing conditions.
