from what I feel hor, 150 less noisy leh, 200 more noisy lor.
petrol wise, i use shell 98, can last about 280km (full tank). one
thing very bad about 200 is that it vibrates alot, not that
comfortable also for long distance. buttocks and hands will numb,
that is when I ride for 30mins straight lor. pick up for 200 also
not bad.
