Dear members,
I own ybr 125 g 2021 with 1800km on odo meter. Rear rim and even rubber of tyre heats up to the level where it can't be touched even after 3 4 km ride. I intentionally rode the bike with out using rear brake for sometime but still rim heats up very much. I got my bike checked from two different authorized dealerships of yamaha and both of them opened up everything and nothing is faulty according to them. Tyre freely moves on double stand. All bearings are ok but still issue is there. I'm very worried as i fear bursting of tyre. Please need your help.

have you compared it with any other bike. how are you measuring the temperature?

What tyre pressures are u running?

I'm just measuring it by bare touching the rim. I dont consider it normal as at times I can't even touch it due to so high temperature

33psi.

What about the front ones ?

Front rim is normal. Air pressure is 25psi

I don't like the idea of having a guess by hands.
Between do you have any aftermarket exhaust near to wheel?

is the hub also heating beside tire and rim?

Did you change the rear drum brake with disk brake? It happened to my bike too when I installed disk brake, so I reverted back to drum

No brother. Everything is stock.

Bhai sahab brake leathers+drum both are new in ur bike they will be making their seats inside drum that,s why you are feeling it.. according to my experience its not an issue everything seems normal just you are feeling it

Reh gye baat front hub+Drum+rim kay heat na honay ki tow front brakes per tow load hota he nahin complete bike ka weight hameesha rear drum+hub per he hota hay

I also noticed the same when i bought the new byke. But after driving 25K it never got any issue. I didnt checked if it still gets heated or not.
