hmm i not very sure about CBR lah but if i'm not wrong there are
these 3 models, RL, RN and RR, in order of age and power.
but if you really wanna get a 4stroke, then i feel get GSXR better,
coz the CBR frame more for road use, some more it's very fat so
will be clumsier than the GSXR.
milage mah... my fren's hurricane full tank last about 240km. he
say roughly is 1l ~ 17km.
by right, the cbr should have better milage than that, but he said
its becoz his bike old liao that's why eat so much petrol
now.
as for PGM maintainence, aiya i hear this argument until sian liao
lah. to be honest i dun see any difference in maintainence.
i pump full tank S$17, travelled the highest is 220km, excluding
reserve which is another 40km.
if you wanna say 2t eat high, 1000km 1 bottle of 2t, 1 month
usually is around 2.5k km of travel, so is around 2~3 bottles of
2t.
engine oil 1 bottle, can last you 3000km.
spark plugs u wanna change or not up to u, anyway so cheap $14 for
2 gold plugs.
unless is your monthly instalments very high, then i nothing to say
loh.
