General description

GASS RS-A aluminium rim – state-of-the-art technology from OZ Motorbike:

Two decades of experience and innovation from the racing of top MotoGP and World Superbike teams flow into the production of the GASS RS-A 6-spoke rims.

The GASS RS-A rim is a further development of the well-known PIEGA aluminium forged rim. The newer GASS RS-A rims are manufactured according to the “FE method” (finite element) – thereby achieving a minimisation of weight with simultaneous improvement in stability and rigidity.

The weight reduction reduces the moment of inertia, which in turn leads to improved acceleration and brake power. The gyroscopic effect when turning in is also reduced – handling is optimised, the bike becomes more agile and manageable.

The weight saving of the GASS RS-A is also immediately noticeable visually: typical for the new rim are the visible recesses on the outer edge of the rim bed – a visual enhancement of the rim.

Weight saving example:
The 2015 Yamaha R1 uses “light” OEM magnesium rims.
The OZ PIEGA saves approx. 1.3 kg per set compared to the R1 OEM magnesium rim.
The GASS RS-A further reduces the weight here. The set weighs around 2.05 kg less compared to the R1 OEM magnesium rim!

rims are delivered completely ready for installation: incl. balllager, anglevalves, spacers, rear sprocket carrierr for two-sided swingarms. For two-sided swingarms, the chainnblatt from the extensive range must be selected and ordered separately.
