A Different Sequence
Every function the street version carries, positioned for circuit use. The most-used control moves to where a thumb lands under braking rather than where it looks tidiest.
More Parameters on an S
Semi-active damping adds another layer of settings, and on a track day those move between every run. All of them are reached from this side of the handlebar.
Washed Hot, Uncovered
A naked bike offers the pressure washer a direct line to its switchgear. Twenty minutes after a session, on warm aluminium, that is exactly what happens.
In the Van Between Rounds
Cold, damp and vibrating for hours. It is where a clipped cover loses its grip, and it accounts for more failed switchgear than the actual riding ever does.
Two Finishes
Black or titanium, grown into the aluminium. Against gold suspension and dark bodywork the choice is between disappearing and acknowledging, and both are defensible.
Standard Comes Back
Nothing spliced anywhere in the loom. The road block returns in twenty minutes and leaves no evidence, which protects a heavily specified motorcycle's value.
Combined Braking for Circuits
Race eCBS applies a measured amount of rear brake from the front lever. On a short naked bike with a light rear end it does considerably more than it sounds like it should.
Semi-Active, Improved
A more capable platform and finer adjustment than the previous generation offered. On a chassis this short, the load genuinely moves faster than any fixed setting could follow.
Mass Taken Out Everywhere
Frame, swingarm and wheels all contributed to the 2025 weight reduction rather than one component carrying the whole saving.
