Uno Quattro Teste di Creazione

 Numero Uno in the early stages

"Uno Quattro Teste di Creazione" (the name of the racing stable) currently has two machines we will admit to. One has been partially completed and the other is at the concept stage.

"Bike uno" is of course based on a Triumph Tiger Cub, the "Cub 150". It is partially completed road racer built from parts of a standard Cub engine and frame. The engine is a point in the side model from approximately 1963, with a 9:1 piston, an "R" cam and features extensive drilling to lighten the weight burden. Much calculation has gone into the theory of it all to produce extra horsepower due to less power lost to driving the weight of the rotating and moving parts. Once a big enough Dell Orto is sourced along with suitable wind tunnel analysis, the thing will be the fastest Cub on the planet. The theory has been dreamt but not yet proven!

The frame is standard Cub with a more modern front end, possibly Honda 250 K2 forks and brake, and clip-ons from a Guzzi. The rear rim is a Borrani laced to a Cub hub with yet to be manufactured snail cam chain adjusters. Much of the steel bits have been replaced by drilled duralumin to give ultra lightness.

The seat is a true work of art. It has been individually moulded from ply to exactly fit the contours of the rear sub-frame. It has a streamlined rear cowling in light aluminium to finish it off. The tank is an aluminium Husquvarna tank hiding a bracing bar in rectangular section steel for support to the steering head.

A new Husky tank has been sourced from e-Bay to replace the borrowed tank above. Unfortunately it is not alloy, but it is lighter than the standard Cub tank and the fuel tap was still there. The alloy tank is now on the trials Cub which looks fab in monochrome.

Best news is that the seat has been covered in warm leatherette! It is a true "work of art" (c) Jack "The Hat" Armstrong. Finely stitched and contoured to perfection beyond our expectations by professionals. Although Numero Uno hasn't moved much for a while we have started to rob bits from the green snotter which will do a turn on this bike. The fork legs are lighter and the perfect length and will be fitted into the Cub yokes - with engineering if necessary.

Another stroke of luck was the discovery that the snotter had been fitted with after market Marzocchi rear shock, after one was removed and lightly buffed to reveal their true manufacture. They were checked and found to be an ideal length for this bike and another bit of the jigsaw fits nicely.

The fork legs from the green snotter have been found to be a better bet than the current ones. They fit very well into the yokes and look very nice. It is now suspended entirely with the forks and rear units from the Kawasaki! Rod has been reworking the top yoke to grind away most of it for a more streamlined profile; it might appear somewhat excessive to streamline the top yoke, but in the pusuit of excellence, every little helps - as a well known supermarket would have you believe! We also found that the twin Mikunis from the snotter fitted the Cub rather well and should improve the breathing. Not many Cubs will have a twin carb Mikuni conversion!

 Further bits have been added to numero uno, with a rev counter centrally fitted to the top yoke. Not so sure anyone will be looking at the rate of crankshaft rotation at 150 miles an hour with stopping provided by Cub brakes!!!

Numero Due 

 "bike due" is a racing outfit based on a Norton wideline frame with bits chopped off and others attached. Most of it is still a "creatione" in Rod's head although some parts have been made ready. The frame does exist although most of the weight is currently in the form of iron oxide lying outside the shed.

The preferred power unit is a BSA A65 engine but I can just see a Hyabusa engine becoming miraculously available for that extra few mph.

Rod is under the misapprehension that Pete is going to do the acrobatics in the sidecar. This is of course a delusion.
