I've had my 2019 CB1000 for a year and I was wondering if anyone else is getting excessive exhaust smoke on cold winter days. It only lasts until the engine is warm. Then all is good.

It's steam. Look around. Every vehicle does it when cold.

If yours is really excessive then you maybe have condensation issue. But I doubt it's anything abnormal.

Agreed, it's normal condensation, not smoke.

Smoke tends to hang around and normally indicates bore wear.--After a moment or two steam disappears.---For every gallon of fuel you use around a gallon of water vapour comes out of the end of the exhaust pipe.--Normally only seen in cold weather. Bit like your breath, can be seen in cold weather too.

It's water vapor. Every internal combustion engine does this during a cold start. In some weather conditions it's more prevalent than others like when breath from warm blooded animals can be seen.
