A 662cc inline four-cylinder engine spinning to 11,500rpm. In a class where twins and triples are the norm, four cylinders means power that keeps climbing right to the top of the tacho, and the soundtrack that comes with it.

Suspension designed to give you the best of both worlds. Progressive Suspension 2.0 is our progressive-rate setup: instead of a single fixed spring rate, resistance builds the further the suspension compresses. The soft first part of the travel is designed to filter out uneven surfaces — coarse chip, expansion joints, mid-corner bumps — while the firmer end of the stroke resists dive under hard braking and holds the bike up when you're committed in a corner. Comfort on ordinary Australian roads, control when you push on, without asking you to choose between the two. A 51:49 front-to-rear axle load split keeps the handling balanced and predictable.

Dual power modes, an electronic quickshifter for clutchless gear changes, and switchable ABS and traction control mean the RR660S adapts from daily commuting to a full-attack track day without missing a beat.

Three seat heights, ten footpeg positions and a stepless handlebar mean the RR660S can be set up to fit riders of very different shapes and experience levels — genuine adjustability, not a one-size-fits-most compromise.
