Suzuki Falcorustyco

About the middle of last when the SuperBike project was announced, TM. in his preamble to the body competition, likened this to the concept cars, fielded by manufacturers at the world’s exibitions. The bemoaned the lack of similar exercises in the bike world. The Falcorustyco and the early 80’s BMW being the only two that readily to mind.

One irate even took TM. to task this and questioned his right to parallels between the large megabuck show vehicles and our efforts.

I tend to agree that reader, after all how can you the two. For a few thousand pounds we, the help of those readers who the competition, have created a significantly different from any on the but its not just a show machine, its up and Just look at the pics.

Its not a one off, more are in the pipe Compare this with concept vehicles, seldom are runners, often having engines and the like. Like as not will be crammed full of way out from the fertile imagination of industrial designers, with regard for technical or economic

Don’t get me wrong, I am the last to try and suppress this type of but as the man said, how do you compare it with our dream machine.

Previous progress reports been about the body and the photos show how little the shape has deviated from the styling sketches. This not have been the case some of the competition entries had been selected, and shows the wisdom of the judges’ choice! The tank is made of aluminium and is into the body.

The construction and use in this country require a petrol container. Otherwise I have just closed in of the fibreglass body and installed a bag tank, racing car style. It have been lighter, expensive and probably safer, but who about SAFETY, its the REGULATIONS count,—- damn it!

The tank was in, rather than being on the chassis for a number of reasons. ;— Ease of mounting, no mounting loads reducing the of cracks in use, stiffens the shell, and removes alignment between the filler cap and the body. just about covers the details so let’s look at the bits and the reasoning behind design.


this is a type of hub centre similar to that used on my QL. and on these pages in the past. In the front wheel is supported on a stub axle which in is located by two sealed ball fitted to what I call an This upright extends to above the tyre and curves to give clearance around the disc and tyre.

The location and permitted movement of this upright is controlled by two one in the shape of an ‘A’ frame the tyre, and the other is a single fabrication mounted just the wheel centre. This arm outward to give clearance for lock. Relative movement these arms and the upright, for and suspension articulation, is permitted the use of aero-space type sperical

The castor angle is ajustable via the rod ends that locate the of the top ‘A’ arm, and will be set at about 18°. and varied testing if found necessary. a side view the locating do NOT form a parallelagram as in many alterative front end designs, they are laid out to give constant anti-dive characteristics, the principles shown in the July issue of this journal.

The intention with this was to use a design of front end that used one locating arm, the one, and no upright, a la 2CV. I have tested a lash up of system and initial impressions favourable, but there is a problem in a neat and practical steering that avoids bump This is not an insurmountable problem, it requires a bit more thinking

However, to avoid further for the time being, I decided to go for the arm design which is now quite proven on several different The design of the main frame for subsequent conversion to the single arm in due

The only real difference the front on this machine and the QL. is in the of the suspension unit. On the QL. this is on the top arm just above the upright. was done because it generally loads and hence can lead to a lighter structure. Whereas on the Q2. the is mounted onto the bottom

Two reasons dicated this reversal of thought.

1. The original of the single arm meant that would be the only place to it, and so will ease any later

2. It gave greater flexibility to the design. Locating the unit in way, introduces vertical tendencies in the arm, which has beefed up accordingly.

The front is the Lockheed developed ISO. ( In Out ) rim disc. This is very and very efficient, and suits design very well.


This is by a single swing arm, and there are main reasons for this,

1. Structural efficiency, for a given it can be stiffer than most sided arms. Perhaps in a issue we can look at actual stiffnesses of various configuations.

2. wheel removal, just a car, undo three nuts and off it comes, without the to disturb the sprocket, chain or

3. Can use a similar wheel to the front.

4. It trick.

Both the front and the ends were designed the outset to use pneumatic suspension, and the Fournales shocks are first in to be tested. Air units give a progressive rate, the degree of depends on the piston diameter and the volume. Because of this is no need to use the currently fashionable, rising rate linkages.

then leads to the mounting as shown. It is simple, light, low in and it reduces loads allowing for lightening.

The wheel mounting hub has turned from a solid of aluminium, for strength reasons, and hub also carries the sprocket and The sprocket is mounted through bushes to give a cush Sealed ball races are use to support this hub on a non-rotating axle ( actually an E-type front axle ), which is in a large aluminium eccentric for adjustment.

Keen students of alternative features will note the swing arm and hub arrangement is considerably from those used on the Elf and those Hondas with a sided arm. On these the swing arm curves in past the and the end is sandwiched between the sprocket and disc. The wheel bearing are into the arm, and the hub is a two piece bolted together and connected by as with some cars.

is a fairly complicated and expensive way of the job but it has the advantage for racing that can be changed rapidly. We have a system more akin to the mono-lever, but with chain and not drive. This leaves the less prone to damage and those with wandering

It also allowed for the simple unit mounting, previously

This has been partially in the original article on the project, and basically of fabricated ‘C’ box sections under the engine. The and rear swing arms are to this at each end. was originally intended for Kawasaki and the steering mechanism and the top front arm were to be mounted off the cylinder

With the Suzuki engine, there are less suitable on the head and so we have a bolted on sub to carry these components.

Well, that’s about it —- except to own up and say that the shown is not the SuperBike project but is for a customer, Paul Griggs. has been staying over in but is from New Zealand, and unless he back there before they won’t let him in again. On to home he wants to ride the USA. and perhaps Australia.

of this Paul jumped the and got his first. But, as Paul’s was constructed several duplicate were made and so the REAL bike should see the light of day soon, but don’t expect any of an actual date.

I think we leave the last word this bike to the inscription on number plate :— VISITING FROM ANOTHER
