not sure about the full-costume, i always keep looking for 'em when in market. but you can get a nice set of elbow+knee pad covers+ gloves for around 500 RS.
Remember? the elbow covers/knee cap covers used for skating normally.
I seriously intended to buy a set of those when i scratched my kneecap pretty badly in a recent accident. normally the areas injured by a bike accident are elbows/knee caps and head.
so if anybody considering buying one. go for it. safety is a must.
i am still unclear if i'll get that set, caz it looks a bit 'cheapo' wearing the riding kit on a 125, ...i think one must have atleast a 400CC heavy bike to go for those accessories, but you cant ignore safety at alll anyway.
