The Bonneville 400 — I've been waiting for this the whole time. Hearing it's spotted running near Pune practically at production-ready spec keeps me up imagining the spec sheet. Translating that traditional design into a small displacement isn't easy. What it inherits from and changes compared to the old big-displacement Bonneville — I'm dying to know.

At this displacement, the price should be kept pretty reasonable too, so it's tempting as a first-bike option.

Didn't know the Bonneville had a 400cc class too - always pictured it as 900cc and up.

It says around September, but the reveal and the launch usually don't line up, so when we'll actually ride it is anyone's guess.

There's always an extra lag between the local reveal and the Japan launch for India-made bikes.

Even calling it 'close to production' has always felt like it drags on and on before the actual announcement, so I'm taking that September date with a grain of salt.

It'll probably be a sibling to the Speed Twin 400, so the landscape for small-displacement India-made heritage bikes could shift again.

More Bonneville 400 sightings around Pune - feels about time for the official production reveal.
