never heard of a cosser, i did race (bmx, hence the name) until my FA was jacked, then i moved into mountain biking and dirt biking (1999 Suzuki RM250 motor is all boyseen, fmf fatty with a power core 2 silencer, forks tuned by shock therapy, no clue about the back end. it was a former race bike that had the piston skirt explode, and from a deal that my dad struck scored the bike, and the guy paid us. lol. new bike AND money to fix it ^_^ )
oh yeah, and nvidia, that mongoose almost looks identical to my friends Haro, except you got some nicer cranks, nicer chainwheel, and brakes.
