By combining the 4MC’s unique designs with leading and trailing suspension arms allows the 4MC to have the following key features and benefits.

Does not require a separate frame
  • Lowers the centre of gravity
  • Minimises weight, 160kg – 200kg depending on engine size
  • Improves manoeuvrability
  • Improves braking
  • Improves acceleration
  • Minimises fuel consumption
  • Minimises tyre wear
  • Minimises production costs

Upwardly looped leading arms
  • Allows a 45 degree steering lock in each direction

Generates a large slip angle to all four tyres in a destabilising event 
  • Resists falling over which increases stability

Generates a high oil flow in all four dampers in a destabilising event 
  • Resists falling over which increases stability

Has a pulsing anti tilt device that works in a rapid destabilising event
  • Prevents falling over

Can use its anti tilt device (without pulsing)  at low speed or when stationary
  • Can travel very slowly through traffic without wobbling from side to side
  • Does not require the rider to put their feet on the ground when stationary
Hand brake and anti tilt device combined
  • Can be parked on any reasonable hill or contour without needing a stand
Variable wheelbase
  • Helps cornering without compromising straight line stability
Side view
Consistent suspension spring/damper ratio with a high oil flow
  • Optimises the suspension damper design to enhance road holding 
Unique but simple steering joints
  • Provides the rider with a good amount of feel from the tyres
  • Contributes towards the light steering

Has a width of only 58 cm
  • Optimum width for negotiating traffic.  Large motorcycles get stuck in traffic, and narrow motorcycles have no road presence which invites abuse from other road users.   The 4MC’s 66cm wide handlebars can be manoeuvred past obstacles and therefore do not add to the 4MC’s 58cm limiting width 

Can be ridden with a car license or full motorcycle license
  • No need for car drivers to retake a test they have already passed.  Although half a day’s off-highway familiarisation coupled to some “what-to-look-out-for” pointers, from an experienced motorcyclist, would be recommended

Designed uncompromisingly to travel through traffic yet;
  • Has a great recreational appeal
  • Will adapt to a much more sports orientated design
  • Will permit further developments
