The RS 660's 169 kg kerb weight is achieved through careful weight distribution and compact component packaging - the parallel-twin engine sits as low and central as possible, resulting in handling dynamics typically associated with 300-400cc bikes rather than 650cc+ machines. The 180/55-ZR17 rear tyre is standard supersport sizing, providing grip and feedback comparable to bikes costing twice as much.

## FAQs

**Is the Aprilia RS 660 engine derived from the RSV4?**
Yes. The RS 660's 659cc parallel-twin uses the same bore and stroke as one bank of the RSV4's V4 engine - it is literally half the RSV4's engine architecture. This means the RS 660 shares cylinder head technology, combustion chamber design, and valve timing philosophy directly with Aprilia's MotoGP-derived superbike.

**What suspension does the Aprilia RS 660 use?**
The standard RS 660 uses 41mm Kayaba USD front forks and a Sachs rear monoshock. The RS 660 Extrema upgrades to Öhlins NIX30 fully-adjustable USD front forks and Öhlins TTX36 fully-adjustable rear monoshock - factory-fitted Öhlins suspension normally found on race-derived homologation specials.

**Does the Aprilia RS 660 have launch control?**
Yes. Launch control is standard on the Aprilia RS 660. It limits rear wheel spin off the line by managing throttle and traction control intervention, allowing consistent, wheelspin-free launches. It is activated through the riding mode system and works in conjunction with the traction control and ride-by-wire throttle.
