its all relative to where you live and what situation you are in
here in indo, the new ninja 600R costs 225.000.000 Rp = almost 26.000 USD.
while the ninja 250 now costs like 55.000.000 Rp = 6.250 USD.
we could buy 4 small ninjas for the price of one 600cc
so far my power mods that have gained me about 10Hp has cost me:
* $1000 for the AreaP exhaust (import tax literraly raped me there... got charged almost 50% on top) - install free
* $100 for K&N filter - install free
* $100 for a Jet kit - install free
* $100 - 200 for the porting - done by the mechanic (haven't paid yet, gonna get one fat bill when the bore up has been done too... lol)
-----------------
$1300 ~ 1400 total so far~
then im still doing the bore up:
* $335 for the JE pistons
* $100~200 for the bore up to 265cc.
--------------
$435 ~ 535 once thats done..
and im hoping to get another 3~5 Hp with this hopefully.
gran total is somewhere around 2k USD... never added this up till now actually, looks expensive now, haha, but i paid it all in small bits, so it did not feel as bad as it looks on the wallet.
ive spent about $860 on other various mods as well... and i dont even have a full ninja, running her naked since i crashed a couple months ago
that was was a pic while i was still installing the new headlamp. i have a 60/55W bulb in that reflector, and its even brighter than the original headlight! sort of tempted to put in a HID, but its actually bright enough as it is hehe~
so back to your comment Kostas, yes, if you can buy a bigger bike for not that much more, and you are confident that you wont kill yourself with 160~180% power increase... do it
drive safe and have a fun week end!
