RS250 uses a Suzuki engine while the exterior is Aprilia.
therfore parts can b replace by RGV250 (not the latest RGV 250 SP
model) the parts is much more cheaper than the orginal Aprilia
parts. and so not as problematic than 125.
servicing will b double since got 2 carb, 2pistons, 2 blocks, many
things bcum 2 lah! so when u service price will b doubled
lor!
anyway does plate really matter? 
example u buy a FQ plate with mileage of 60K, goes to track often,
while the othe FN plate, low mileage of 20K n doesnt go
track!
which will u choose? obvious!
there r only very few FQ plate, should b 3.
but there r very few RS250 ard liao!
i got my RS250 for only 4 days n it need a overhual! setting a few
Ks aside will really help.
price of the bike will depend on condition! anyway should cost ard
6K+, depends on the accessories, new parts, overhual...etc
anyway if u really interested, i m selling mine.
FN plate,with considerably low mileage, just top overhual with
recipt, new pistons, rings, block service, valve..etc
full arrow system with single seater, 2nd party insurance still
quite new, michelin pilot sport rear..etc
many new parts to b mentioned! but oso some wear parts!
