Yellow pasta

Here is the story of the yellow strong Laverda by Gérard Livet
My motorcycle is a triple cylinders 1000cc  laverda in 1975 racing outfit. At first she was completely of original layout except a pair of clips-on bars and a single seat.

After years of road usage  and important mileage, I decide in 1998 of a complete refurbishment and especially on a transformation in a 70s racing style about which I dreamed for a long time. The engine was completely renew from new with racing parts, forged high compression pistons, 4c camshafts and three 36mm Dell' Orto carbs .

Thanks to Charles Dufetel and Richard Gallici for their skills and help to carry out this mission. polyester parts were made by Jean-Jacques Vilmot, thanks to him also for is collaboration and working quality.

The seat is a Honda CR replica which I extended slightly with a bight in the middle for a more Italian style. The tank is a SFC, the front fender comes from of an Aermacchi and the front fairing is a Seeley. Clips-on and rear sets are home made.

Wheel rims are Borrani’s with stainless spokes. Now for 4 years on circuits, I participate in some events organized by various clubs and associations, particulary Coyotes Days where organization and atmosphere are great.

The laverda is plenty of torque, powerful and pleasant motorcycle to ride on tracks, a little bit heavy but how much charming. I always liked the 60s and 70s motorcycles and especially cafe racers style which gives them an unmistakable charm and then the Continental Circus movie that I saw in the time was a reference for me.

The Norton 1927 CS1

last week we saw the Energette.Now lets talk about another fabulous machine: the CS1
A great thanks to Ken McIntosh and enjoy ...


Designed by Walter Moore, the CamShaft One (CS1) engine appeared in 1927, based closely on the ES2 (pushrod) engine and using many of its parts. On his departure to NSU in 1930, an entirely new OHC engine was designed by Arthur Carroll, which was the basis for all later OHC and DOHC Norton singles. (Moore's move to NSU prompted staff to claim that NSU stood for "Norton Spares Used") That decade spawned the Norton racing legend. Of the nine Isle of Man Senior TTs (500 cc) between 1931 and 1939 Norton won seven.
CS1 1931


1929 Norton CS1
By Ken McIntosh

The CS1 (C = Camshaft, S = Senior, 1 = Model 1) was designed by Walter Moore to replace the push-rod OHV motor designed by 'Pa' Norton, and combined with the new cradle frame was a huge leap in technology and styling.


The CS1 won the Senior TT first time out, in 1927 and even more remarkably an unknown rider Tim Hunt won the 'Amateur TT' in 1928. Open only to private riders on private machines Hunt won at a speed higher than the TT record. He used the same bike in different trim to take a Gold Medal in the 'Scottish Six Day Trial'.

Strangely further development bought little success and the push-rod Sunbeam and 4-valve Rudge proved dominant until Irishman Joe Craig reappeared on the Norton scene and helped design a new motor with Arthur Carroll for 1930.


Despite its failings the CS1 must rate as the best looking 'Vintage' bike ever, and riding it back to back with my 'Flat Tank Model 18' it is a huge step forward in both handling and comfort. The engine is mechanically stronger, with steel flywheel (replacing cast iron), bigger main shafts and bearings, and through-bolted cylinder studs.







In full TT trim, with close-ratio kickstart-less gearbox, 8 inch brakes, Amac TT carburettor, Lucas Racing magneto, and the beautiful 3-gallon petrol tank and wrap-around oil tank it set the style for racing Norton's for the next 20 years.
