From the Greeves website :
The new Greeves Trials Bike has been designed to give maximum performance, reliability and ride ability without compromising on quality.
In excess of six thousand hours of design and development work have been expended into the new bike in order to provide the ultimate riding experience.
Maintaining the bike is very simple. We have chosen and fitted some of the best branded products in the World to the trials bike such as:
* Marzochi Aluminium forks
* Italian gears and internals
* Dellorto Carburettor
* Greeves Crank Shaft
* Surflex Clutch has a CNC'd aluminium basket with 16 splines
* Ohlins Shock
* Tallon Hubs
* Regina Chain
he Headstock is typical Greeves. This outstanding design, produced from high grade Aluminium is strong and proven over forty years. The air box is high up by the headstock to prevent the entry of water from the back wheel. The petrol tank is situated low down close to the rear wheel to lower the centre of gravity to improve traction.
The shock absorber is mounted centrally, directly on the swinging arm at a precise angle to give the back end of the bike more manoeuvrability proving less tiring for the rider. No linkage is required. The back wheel has improved grip alleviating shock rebound on large steps.
greeves new trials bike
Greeves have designed their own engine which is manufactured in the UK All design work has been undertaken in-house by Greeves Engineering & Design. The crank cases and outer covers are CNC'd in the UK.
Barrels and heads are also produced in the UK by a local foundry. The barrel has a 360 degree water jacket with no interference with head studs that tend to make the piston nip up when the engine gets hot - the barrel can expand with the piston equally 360 degrees.
The head is clamped down outside the water jacket using a specially designed head, aluminium insert and O-rings.
Wheel spindles incorporate spacers so there is nothing to lose if the wheel is removed to change tyres. Plastics can be clipped on or off without losing clips. The radiator is set back to prevent overheating if mud builds up on the grill. This can be quickly cleaned if required.
greeves fuel filling sytem filler and vent
The fuel filling system is unique with no large caps, just a 10mm diameter inlet. This will allow 3.5ltrs fill in thirty seconds.
The engine can be removed and replaced in around forty-five minutes. The swinging arm spindle has bronze bushing to prevent rusting.
The frame is produced from special Aerospace material extruded into a special shape for strength and appearance.
We are planning to produce four versions of the Greeves Trials Bike: 125cc, 250cc, 280cc and 310cc
