hey everyone i just picked up a 2001 Nija 250. is there any info you guys can give me about this bike? anything i should know? also i need new tires can anyone recomend any good tires? and what size should i get? can i get a bigger rear tire? stock is 130 can i go bigger? also i will prbably do some performance mods to it later on, so what are some of the main mods people do? ive heard Muzzy F/S exhaust are good so ill probably get that later on. i really need help on tires tho so if you could help e about that, that would be great.
