Not sure about road tax and scrap value, but HDB parking fee
should be the same for all bikes, isn't it?
2.petrol wise,how far can u go with $10 on sp and on
rxz?
Based on my experience...
RXZ can travel 27-28 kms per litre of petrol.
SP varies between 20 to slightly more than 25 kms per litre of
petrol, depends on your riding style.
3.does rxz need 2T?any 2b bike no need 2T?
Of course, RXZ is a 2-stroke bike. All 2-strokers need 2T. All
4-strokers don't need 2T, and there's quite a lot of 2B 4-strokers
in the market, like Phantom 200.
5.For rear brake,disc or drum better?cos sp is disc and
rxz is drum...
Theoritically, disc is better than drum. All sport bikes
nowadays use disc rear brake. But my SP's rear brake is a bit lousy
Dunno if other SP riders also have the same problem...
6.Heard rxz is a very problem free bike with high resale
value..is that true?if no,what are the bad points of
rxz?
Problem free... true
High resale... quite true
Bad point... not as good looking as SP
