This Moto Guzzi Le Mans has the Lanfranconi Competition Exhausts, which were an option when new, also fitted with 3 linked Brembo Disc Brakes and FPS Alloy Wheels, Koni Rear Shock Absorbers and Air Assisted Front Forks.
The Moto Guzzi Le Mans is a sports motorcycle first manufactured in 1976 by Italian company Moto Guzzi. It was named after the 24-hour motorcycle endurance race at Le Mans in France.
Basic design of the Le Mans remained essentially the same throughout the production run.
The engine, developed from the earlier Moto Guzzi 750s, is an aircooled 90 degree OHV V-Twin which was at the time an already proven Moto Guzzi design that had been in production in various forms since the late 1960's. Like previous models the engine is mounted longitudinally in the chassis (Crankshaft inline with the wheels) presenting the air cooled cylinders to direct uninterrupted airflow and allowing a direct powertrain to the rear wheel. The V-twin configuration gives improved ground clearance over an opposed 'Boxer' layout, allowing the engine to mounted low in the chassis. The single camshaft mounted in the crux of the V operates the 2 valves (per cylinders) via pushrods and is driven by a short double row cam chain. The cam chain mounted on the front of the engine also drives the oil pump for wet sump lubrication.
The power output measured at the back wheel was 71 bhp, giving a top speed of 130 mph. Compared to its roadster sibling, the T3, the Le Mans had higher-compression domed pistons, larger engine valves, and Dell'Orto 36 mm pumper carbs with filterless velocity stacks.
The Le Mans 850 or Le Mans Mark I (never officially labelled Mark I), was first shown at the Milan motorcycle show in November 1975 and sales began in 1976.
The Le Mans had three production runs with very slight modifications:
The first run, Series A, had a round CEV taillight, low 'racer' seat that was unusually a made of a single molded foam item, silver fork legs and various minor detail changes and continued in production until at least September 1976. Although it is often stated that fewer than 2,000 of these were made, Ian Falloon claims 219 were made in 1975 and a further 2,532 in 1976 although it is possible some of these were Series B bikes built at the end of the year.
The Series B run was 4,000 (2,548 in 1977, 1,737 in 1978).
Falloon gives total 850 Le Mans production as 7,036. Series B bikes had these modifications: a De Tomaso-designed rectangular taillight with a modified rear mudguard, black fork sliders, small heel-plates, cast fuel taps and a more generous dual seat.
Series C bikes gained ridges on the heel-plates. Most bikes were red and black, but a few were metallic blue (Ice Blue), even fewer were white.
The original 850 Le Mans was a café racer with clip-on handlebars and a bikini nose fairing, but in the face of more and more powerful bikes from other manufacturers later models were developed more as sports tourers with a three-quarter fairing. A marketing success, the Le Mans competed against Italian superbikes from Ducati and Laverda. The original Le Mans was continually developed and spawned several later models, a final versions appearing in the early 1990s.
The Mark II was similar to the Mark I, but the small 'bikini" fairing became a larger full fairing, in three parts, incorporating indicators. The fairing had been tested in Moto Guzzi's wind tunnel (which had been used to test race bike fairings in the 1950s). The new fairing had a rectangular headlight, rather than the earlier round item. later bikes saw an oil sump spacer to increase internal volume and move the oil away from the crankshaft and cylinder bores were updated to alloy coated with Moto Guzzi's patented "Nigusil".
The front forks were slightly changed and now held slightly wider in the yokes (triple trees). The seat was the same as the Le Mans and could comfortably carry a pillion. Further changes included a revised instrument cluster derived from the 1000cc SP. Brakes were linked, with the handlebar lever operating the front right caliper and the footbrake operating both the front left and rear caliper via a simple splitter.
In 1981 a major redesign saw the tank, seat, fairings updated. The engine saw considerable updates with revised cylinder head and barrels, with a squared-off cooling-fin design. The sump spacer was now standard and the breather box was now replaced with condenser that used the upper frame rail. The pushrods and cylinder studs were moved further from the bore centre, allowing for the future increases in cylinder capacity. The engine had improved machining tolerances, revised intake, carburation and exhaust systems all of which gave an increase in power and torque despite the (official) slight drop in compression ratio.
A true proportioning valve was fitted to the linked brakes, improving the braking performance and later models had revised cast wheels although still with tube type tyres.
Absolutely stunning bike.
I just inherited my dad’s Le Mans 1000 IV SE rare Color scheme with white/black with gold decals from 1988.
It has la fraconi exhaust aswell. It’s stunning
That’s awesome. A rare colour scheme for sure. I would love to see a picture if you want to send one to dalesvids@aol.com 👍
Came for the exhausts left after the fekkn violins , nice bike tho
Hi, where did you get the handle bars from and did you have change the cable lengths ? Thanks
@@reubenfox9765 Hi they are renthal superbike bars, bought from an auto jumble. Cables are standard length 👍
Thanks. What about the headlight, is that a guzzi headlight ? I've just brought the same model and I think the look & riding position will suit me better that you have created with yours. Looks great by the way.
is that a renthal medium or high bar ?
Medium height bars
@@JohnHemsley-ft2ck thanks John, is it a guzzi headlight ?.
A close family friend who us kids called “uncle Percy” had one of those, but sold it when he won a Laverda at the Isle Of Man TT. I still have the picture of me (somewhere) sitting on it aged around 5.
Then a fortnight later it was stolen and stacked into a wall, leaving a very p****d off uncle Percy 👍✌️
Wow winning a Laverda at the TT that’s awesome 😎 👍
@@Dalesvid yeah as my ol grandad said “ever seen a dog with two d**ks” 😂 THAT was uncle Percy 👍✌️
Nothing else sounds like a le mans with Lafranconis, thats why I will never sell my le mans ;)
That’s for sure. It’s a keeper 👍
