This is the sportiest and lightest RS 660 in the range. Thanks to its refined and new standard equipment, RS 660 Extrema tips the scale with an amazing kerb weight of 166 kg, raising the bar to new heights in terms of weight to power ratio (which comes in at 100 HP, a record in its class. The standard equipment includes a new and lighter street-legal exhaust system by SC Project with carbon silencer positioned on the right side (and no longer beneath the engine). Also contributing to the overall reduction in weight are the front mudguard and the new under cover below an engine with a brand new design, both made of high quality carbon.
The sport derivation of RS 660 Extrema is also emphasised by the single-seat tail fairing (the passenger’s seat comes with the bike); In addition to the standard electronics on the RS 660 (which include traction control, cornering ABS, engine brake, engine map, and wheelie control – all adjustable) RS 660 Extrema also has software that allows you to set up quick shift in upside-down configuration. This means that the gearbox can be configured completely autonomously, without replacing any bike component, in street or race version – ideal for track days.
