The front suspension has been completely redesigned. Many of the components have been replaced or specially modified, with the aim of improving front end stability and capacity to absorb bumps.

Rider comfort has been much improved through a reduction in pitching, giving greater confidence at high speeds.

From a technical point of view, the changes involve the following parts:

New pistons. A radical but very important decision, which has given the hydraulics a 50% increase in effectiveness compared with the previous version.

New damper rods with a hardening treatment designed to reduce stiction and increase stability of performance over the long term

New bushes to improve overall smoothness

Hydraulic cartridge filling modified to improve the oil bath and reduce any emulsification
 

Fork springs now have less rigidity to suit the new operating conditions

Forks reconfigured for wider spacing between centres (+ 10mm) for greater versatility in use.

Shock absorber adjustment. We have taken a fresh look at the rear suspension to allow new settings in order to optimise behaviour in partnership with the modified front end.

New wheels.  In the 2009 version the RR runs on lightened Excel wheels front and rear. This provides a sharp reduction in unsprung weight (over 900g), combined with remarkable rigidity, achieved by the use of:
o New lighter steel spokes
o New aluminium spoke nipples
o New lightened wheel hubs

More comfortable seat.  The seat has been redesigned and filled with more suitable foam for the type of use the bike receives. This modification has increased rider comfort, and will be specially appreciated by people who often use the bike for long periods.

New colours and graphics.  A brand new white colour-scheme has been introduced, made even more exclusive by aggressive new graphics in fluorescent red.

RR4T SPECIAL EDITION VERSION

These bikes will be produced in limited numbers.

Here-below the technical differences that this bike will present in comparison to the standard version:

1. 50mm Marzocchi forks
Fitted with sealed internal cartridge and totally revised components. We need to emphasise that this version too has totally redesigned pistons, with a 50% increase in hydraulic action capacity. The larger-diameter stanchions on this Magnum version give the bike greater stability.

2. Fork yokes machined from solid
In aluminium with variable offset and bright red anodising. In combination with the new stanchions, they give greater rigidity to the front end, bringing increased precision to the ride.

3. Rear shock absorber 5 mm longer
To give greater ground clearance.

4. Full titanium Leovince exhaust system
With straight-through silencer and decibel-killer at rear end. Use of this system means a very considerable saving in the bikes overall weight and results in a more linear and full-bodied delivery, while being fully compliant with the legislation.

5. Racing electrical system
This means lighter and simpler electrics, designed to improve practicality and maintenance

6. Stealth aluminium rear sprocket
A vitally important component which in this configuration, using titanium fixing pins, manages to combine the best qualities of aluminium (lightness and rigidity) and steel (long-term robustness). With its striking black and red colour scheme, the sprocket cannot fail to catch the eye.

7. New lightened Excel wheels
Fitted both front and rear. These Excels enable a weight-saving of over 900 grams compared with standard, while maintaining extremely high rigidity. They use new lighter steel spokes, new aluminium nipples and new lightened wheel hubs.

8. Other

Inner front disc carrier
In black
Racing number plate
With LED miniature headlamp. The shape is more functional for use in competition and improves the look of the bike.
Rear mudguard air intake
In robust and ultra-light carbon fibre. Here too the shape helps to give a more personal look to the bike.
Hand guards
Impact-resistant, giving good protection.
