I own bajaj Pulsar 200NS completed 23000+kms on odo.
first of all bajaj has done a great job created 1st indian motorcycle to have a liquid cooled engine.
Its engine is pretty much smooth and radiator keep heat in check and not allow engine to get overheated on high speed and in city riding.
I tried petronas 15w50 semi synth, castrol power1 10w50 full synth and bajaj stock oil.
castrol power1 is amazing in terms of performance.
it maintains its viscocity during high speeds.
pulsar 200ns have perimeter frame, which provide high stability during cornering at the same time it save a lot of weight compared to diamond tubular frame.
Handling is amazing on high speed and during the corners.
It set a benchmark.
Looks I will give 10/10
and always wear helmets and gear while riding the bike.
safety comes first and ride safely.
