Kove's New 660X Midweight Adventure Bike Emerges, Lighter and Meaner Than the 625X

Kove has a new midweight adventure bike on the way: the 660X, a mechanical evolution of the existing Kove 625X that shows up leaner and slightly stronger in leaked Chinese type-approval documents. I’ve had three tabs of Kove’s configurator open for two years now like they’re going to change something. They haven’t. This might.

Despite the name jump from 625 to 660, the real displacement bump is smaller than it sounds: the parallel twin grows from 581cc to 626cc, the bore stretching from 76mm to 78mm. Kove’s naming has never been shy about rounding up — the 625X wasn’t 625cc either — so file the 660X badge under “vibes,” not spec sheet.

What’s actually changed

Power climbs to 49kW, up from the 625X’s roughly 46-47kW — a modest gain, not a leap. More interesting is the weight: fully loaded with the same aluminium side and top cases, the 660X comes in at 236kg, 3kg lighter than the outgoing bike carrying the same luggage. Getting more power and less weight out of the same basic platform in one refresh is the kind of unglamorous engineering win that never makes a press release headline but shows up every time you’re wrestling the thing off its centre stand.

The 660X also grows slightly in the dimensions that matter for a tall adventure bike: 2,290mm long and 1,395mm at its tallest point, both up marginally from the 625X, while width stays put at 935mm. Tyres are set at 110/80-R19 front and 150/70-R17 rear, the same road-biased 19/17-inch split the 625X uses rather than a full off-road 21-inch front.

Chassis and bodywork carry over from the 625X essentially unchanged, so this reads like a mid-cycle engine and weight refresh rather than a ground-up new model — the kind of update Chinese manufacturers increasingly ship on their own schedule instead of waiting for a formal model-year changeover, which is exactly the pattern Kove’s 350 Rally patent filings showed lower down the range too.

What we know / What’s still unclear

What we know: - The 660X’s specs come from leaked Chinese type-approval paperwork, not a Kove press release. - Displacement, bore, power and weight figures are locked in by that paperwork. - Styling and chassis are unchanged from the current 625X.

What’s still unclear: - No official launch date from Kove yet. - No pricing, for China or for export markets. - No confirmation yet that the 660X replaces the 625X outright versus sitting alongside it. - Whether — and when — it reaches Europe at all. Kove’s 625X and 800X already sell here, so a 660X follow-up landing in EU showrooms within a year of the Chinese launch would fit the pattern, but that’s an inference, not a confirmation.

Kove’s been the quiet one of the Chinese ADV brands lately — CFMoto gets the marketing budget, QJMotor gets the MotoGP paddock presence, and Kove just keeps quietly quietly filing type-approval paperwork for bikes that are actually good. I’ve said “next year, Morocco, on something with 19/17 wheels” for three summers running now. The 660X doesn’t change that timeline. It does mean I’ve now got a fourth bike to research instead of book flights for.

When will the Kove 660X launch?

Kove hasn’t announced an official date. The specs surfaced through leaked Chinese type-approval documents, which typically appear months ahead of a formal reveal.

How much will the Kove 660X cost?

No pricing has been announced for China or export markets.

Is the Kove 660X replacing the 625X?

Unconfirmed. The two share a chassis and bodywork, and the spec changes read as a mid-cycle refresh, but Kove hasn’t said whether the 660X replaces the 625X or sells alongside it.

Will the Kove 660X come to Europe?

Not confirmed yet, but likely eventually — Kove already sells the 625X and 800X in Europe, so a similar rollout for the 660X would fit the brand’s existing pattern.
