Does it have to be new?
If used many options for 4 cylinders japan naked bike
kawasaki z900 or suzuki gsx-s750 are both solid choice.
Both can be found under 40k

for sport bike.. only cbr650r fits your criteria but like the cb650, would be over your budget

other than 4 cylinders, you have ninja 650 and z650, they are also beginner friendly

If new I'd pick cfmoto over the qjmotor, cfmoto simply has better finish and feels more premium

srk600 isnt that bad maybe you'd actually like it when you get on it. I've seen some of them on the road

are you sure this is what you want as a first bike? all the bikes you listed arent beginner friendly.. buy new also guarantee to drop

i think imotorbike is a good place to buy.. one user just bought mt09 v3 from there

here is gsr 750, should fit your budget
reputable shop also, bought from them before
newer model gsx s750 also got in the shop

also found this used cb650r, cheapest in mudah so far.
but mileage already 40,000+ km, so might need to fork out some money for major service like vc, spark plug, etc
