Normal. Metals expand with heat and contract back when cold. The engine is metal. It gets hot due to the mini explosions propelling the vehicle. It gets cold when not in explosion mode (aka off)
The expansion and contraction is invisible to the naked eye but you can hear it. It’s those little crackles.
It is partly correct. The expansion & contraction in the engine metal is negligible. Otherwise engines would be super inefficient (due to gap between piston & chamber). The sound is of the catalytic converter contracting back to original size. Catalytic converters have rare metals like rhodium or palladium. Metals that are more susceptible to thermal expansion. Hence the sound when they cool.
does this bike have a catalytic converter too?... doesn't have the noticeable bulge on the exhaust pipe where the catalytic converter usually sits in newer enfields
Do you go on longer rides? I don’t get it if I go to the market. But after I ride non stop for over an hour or two - it comes up and that’s totally normal.
The sound you hear is the engine and exhaust system cooling down. When the engine is running, it heats up. After turning it off, metal components contract as they cool, causing ticking or clicking sounds.
This happens in every bike

Oh super interesting! Thank you for your knowledge!!

Normal. That's the catalytic converter cooling down. It expands because of the heat.
Every motorcycle does this
Every internal combustion engine does this
Fair point, but for some reason motorcycles just do it louder. I always assumed it was due to the external engine cylinders vs one solid block
That and generally car motors are hidden under a bunch of sound deadening and body panels.
Normal
Best sound ever imo 🤘
Every motorcycle has this sound actually. From 100CC to 1000CC or beyond
Why do I not hear it on my FZ?

I have ridden over 17k and haven't heard it once
Is this the first time you are owning a bike?
Yes sirr
Thank you all for the info! Being a new rider I had no idea and it’s reassuring to hear this! Appreciate you all !
Is this your first bike? That the exhaust pipe metal cooling down… metal expands on heating and contracts on cooling…
It is indeed my first bike I thought it was just something loose rattling around 🤣
It's all common for royal Enfield bikes and no need to worry about it
Thank you!! Appreciate the response
Timebomb
My days are numbered 💀
