Four taglines were associated with Kirk bicycles:
'You ain't seen nothing yet' , 'Nothing else comes close',
'The way ahead' and 'The one and only'
Two quotes were used to advertise them:
'You can jail the revolutionary, but you can't jail the revolution'. (Huey Newton)
'I could be the catalyst that sparks the revolution. I could be an inmate in a long term institution. I could lean to wild extremes. I could do or die.' (Ian Dury)
The Kirk Precision gets its name from the fact that the frame is precisely aligned, thanks to the extensive use of CAD/CAM.
Every frame is die-cast in just 40 milliseconds at 650C under 650 tonnes of pressure, in the world's largest hot chamber facility.
The Kirk frame is the result of 10yrs research and development by aerospace engineer Frank Kirk.
Computer aided design helped match the unique qualities of magnesium alloy to the demands of the cyclist.
Precision die casting and computer controlled robotics ensured the perfect alignment of every frame.
X-raying, and subsequent computer analysis of every frame cast, provided the highest levels of quality control.
A worldwide patent guaranteed that Kirk frames will remain the 'one and only'.
Magnesium is the lighest structural metal known to man - one third lighter than aluminium.
Kirk frames only used High Purity Magnesium Alloy for superior mechanical strength, excellent damping capacity and remarkable stiffness.
The Magnesium Alloy qualities of a Kirk frame, whilst being immensely durable and highly resilient to impact damage, will not fatigue with age or rust.
Magnesium is an environmentally sound choice as only 0.01% of the Ocean's resources would be depleted if worldwide consumption quadrupled, and was used at this rate for a million years.
Only one and a half cubic metres of sea water is needed to provide enough magnesium for one Kirk frame.
Frank Kirk's pioneering developments with magnesium have received prestigious international design awards.
'First Edition' Racer and MTB frames were made by the same die-casting tool by changing the seat and chain stay tool inserts.
'First Edition' frames were manually machined and deburred.
When Norsk Hydro bought into the company, dedicated die-casting tools were used for the Racer and MTB frames.
Although robots were later used for machining the main profile and holes, they proved unsuccessful for surface finishing and manual operations returned.
Pre-threaded alloy inserts were used in the bottom brackets.
Panels and fixings were hot glued into frames, via a conveyor belt and oven system.
The die-cast tools were the largest of their type in Europe at the time and were manufactured in Portugal.
The die-cast press came from Germany - Frech.
High speed profile routers came from Italy.
The robots were Swedish.
Two separate boring machines were used, both designed and built in Birmingham, England.
The powder coating of the frames was done in-house at the Kirk factory.
