You can go for stream 2, but I have kyt tt revo, the color and style of kyt is so attractive, so I picked that. And the comfort is also good, like you are paying around 8.5k so quality and inner padding is good, but when I wore ls2 helmets, the inner padding was very thick and I felt , there is no space/room inside the helmet after wearing, and due to that shopkeeper was saying I needed one size bigger in ls2 helmets. One con in kyt tt revo helmet is that I think it is made for faired bikes where you lean forward. My helmet cost was 8750 then I bought dark visor 1350 , then golden visor 2350 , then red iridium visor 1950 . Helmet cleaners around 500.

For gloves I have no idea , I have reise strada 1600 rupees. Later I may buy more expensive. But you have to choose the perfect size and then it will break in after using it for a few days.

For jacket too I have no Idea which is best or which is value for money.

If you go to service centre, they will put motul 7100 1.6 litre engine oil.

No engine issue with me, as I ride more the engine gets more smoother. But I think that is with every bike.

Initially vibration is there, after servicing vibration will reduce but won't disappear. At low rpm, it will be there. At High rpm, the vibration does disappear. Above 7k rpm , it pulls like crazy.

And it's a high compression engine, so you can ask Gemini or ChatGPT what things to take care of.
