Hub centre – a brief history.

The – a brief history.

Hub center is not new, lets get that straight away.

The first put into production were in the and was ironically made for women to Normal motorcycles of the time really only bicycles engines and so had a cross bar etc… who wanted to ride motorcycles forced to dress like a man the done thing at all at that There was clearly a need for a motorcycle” that could be ridden in the skirts of the time.

In response to need Carl Neracher in up with his NER A CAR design.

This did with the cross bar and front He therefore needed a new system to the front wheel. Hub center was born.

Hub center steering and went over the next 50 with every so often a showing his version or drawing of the Forks by now had developed from bars (girder forks) to and although heavy and with moving parts they the normal fitment. Designers directed into improving

With the advent of the Japanese 1960s) motorcycle engines got and more reliable over a short period. Chassis struggled to keep up with and the result was that 1970′s and 80s are not renowned for their handling on the

Many firms started up chassis helping aids or chassis. Harris, Moto Spondon etc…

But we are jumping here though, lets go a bit to 1967…

One man in his workshops in Frome thought the hub center steered was worth another visit and to make his ideas fit standard of the time.

“Jack” Difazio his first front road with his hub center steered end in 1969.

Left – is the first chassis with a 350cc AJS motor. It wasn’t perfect but you to start somewhere and this is the of our modern tale.

Difazio around 50 bikes in the 1970′s for the and most survive. I first saw the in the late 1970′s and early as a budding new engineer and motorcyclist. articles told of no dive and suspension….I drew sketches and

Several other designers up on the idea that forks limited including Royce (who worked with for his own first project). Tony James Parker, Elf, Brittan and loads more, but all had one in common. They were engineers or small companies and were tight.

Only the ELF was truly pushed forward and was to a successful even at grand level but its single sided arm always be too heavy and wide corner clearance issues. In the when Elf pulled the plug on the team the idea looked once more.

This is the Elf race bike raced in the by Ron Haslam. This is the Parker NOT the Difazio design we use.

The Performance Vyrus project from the graduation work of two engineering students who, the 1980′s, designed and developed a utilising

a front swing arm as the suspension.

Bimota decided to major resources to the refinement of project and hired the 2 young The end result was the Bimota Tesi 1D. The 851 engine produced good for the time and the bike was raced by Cathcart in the Bears series and was successful BUT handling issues existed and unfortunately some issues. There were too many joints to the steering and so did not connected to the front wheel.

This lack of feel and a distribution problem made the “interesting” at high speed own words).

Bimota Tesi 1D

It was fast, powerful and handled enough to win races, but before the could be developed further, ran into financial troubles and the disappeared.

The next step…..

VDM a small but innovative motorbike based in Rimini and headed up by Rodorigo, a former Bimota redesigned the bike around an air Ducati engine and gave to the Bimota Tesi 2D bike in (the Bimota was a rebadged made in the small workshop on the of Rimini).

An incredibly light built using the best high-tech components.

This has now brought back inside the factory and together Alto and Vyrus agreed to go racing and the design even further modern technology.

In 2007 Alto performance back to their British a basic rolling chassis Brothers Ben and Aarron Shaughnessy 9 months solid building a race bike using a ST2 engine. “We used the St2 motor as it was out of a touring bike and we could be accused of doing well because of the engine. This was a test of the chassis design. We the British Thunderbike UK series it was a  series where power is to weight.

We had already come 3rd in the with our Laverda 750 race in 2007 so we figured if we could the bike to be the same weight, the same rider AND the same then the results would be to the chassis. A proper test to back. Is the chassis better OR 3rd in the British Thunderbike uk series and wins in our first year there was something to the design and we did produce the same power as the

So we thought well this really is worth trying with.

Time to move the to the next stage….

2009 was a fantastic year we missed winning the Championship by a 11 points. An engine bearing and puncture denying us the crown.

statistics :

27 races

19 podiums


2 outright lap records

We have the concept so where now?  We early in 2008 that the worked so brothers Aarron and Ben the plan would be in 3 stages.

1. 2007 – 2010

Original which we have raced and successful. – this is now completed.  We tons of data and experience with this bike and winning but its have been reached.  In original bike was put ”out to

   We decided it was not possible to update any with out compromise so this is now…..a door stop!

We to design a new bike in 2010 and the was to build the new bike in 2011 but our became ill with … and brothers decided to put the bike on ice this was beaten.    We are glad to our mother is one tough surprising really) and is making a recovery.

Stage 2. 2012 – 2013/14

New (test bed) with adjustment and with the chassis altered to all the data we had collected from 1. This bike also has a lot power and we expect this to the chassis further. There is a new package with a new style of control, and much more. :

New chassis

New bigger power engine.

New electronics package.

New dynamics package.

This is 90% complete at the time of writing 2012). We will run this in
